Acusera 24•7 Live Online – Version 2.0
Randox Quality Control are pleased to announce the launch of our brand new version 2.0 of our interlaboratory data management program – Acusera 24•7 Live Online Version 2.0.
The launch of this new version has seen major updates and improvements to the software and gives Acusera 24•7 Live Online the edge over many other competitors.
Updates to the software include real-time updates of peer data, more comprehensive charts and reports, bi-directional connectivity, speed improvements and a complete make over to the dashboard. Below, some of these updates are broken down and outlined as to why they are important for a laboratory.
Peer Group Statistics
The biggest update to Version 2.0 is definitely the ability to review peer data in real time. Previously, peer group statistics would have been updated every 24 hours, however, with this new update, data will be available to review instantly! The ability to generate peer data live in real-time will enhance the laboratory’s troubleshooting capabilities and allow labs to compare their data with others around the world. On top of this, there is no deadline for submission like some of our competitors, meaning labs can get a true reflection of performance at any time. Ultimately, labs will have the ability to identify if an issue is unique to them or if there is a widespread issue amongst their peers. Information such as this will allow laboratories to establish a root cause much quicker and therefore spend less time troubleshooting poor performance.
Reports & Charts
With version 2.0 reports and charts are more flexible than ever before. All reports can be generated for a user defined data range and will provide the lab with a whole wealth of information. Reports available on Acusera 24.7 Live Online can include; Statistical Analysis, Statistical Metrics, Audit Trail Reports and the new Exception Report. These reports, coupled with user-friendly and easy to interpret charts, such as Levey-Jennings, Histograms and Performance Summary Charts, enable rapid and stress-free performance monitoring. The ability to add multiple instruments, QC lots, analytes and events such as calibration and reagent lot changes to a single chart allows for comparative performance assessment and immediate identification of any trends.
Communication & Flexibility
The new software is now also capable of bi-directional communication with LIMS. This is a benefit to any laboratory, in the event of a QC failure or rule violation the 24.7 software send a message or alert back to the LIMS. Acusera 24.7 is designed primarily for use with our Acusera range of true third party controls, however, our software is flexible and can therefore be used with any QC material. Performance limits, QC multi-rules and peer groups can now be customised to suit each individual laboratory depending on user preferences for each different analyte, instrument or lot of control. Alternatively, users can also create custom configurations that are able to be shared across other instruments in their labs and within their groups.
Sigma Metrics & Uncertainty of Measurement (UM)
Version 2.0 of Acusera 24•7 Live Online comes with the automatic calculation of Sigma Metrics and Uncertainty of Measurement (UM). The benefit of automatic UM calculation is that it will help laboratories meet ISO 15189 requirements. Automatic Sigma Metrics calculation is included and is designed to help improve QC strategy design.

T’was the week before Christmas and all through the lab not a thing could be heard not even a sound. The analyser lay silent asleep in the corner, the lab staff at home dreaming of a few days’ rest, only a few more days to go before the big day!
The big man in red, what will he bring those who already have everything? Peace, happiness and health for their loved ones throughout the festive break, that would be the wish for everyone to make. And what better way to ensure they stay healthy, well it all begins in the laboratory…
An important consideration to remember when choosing your lab Quality Control (QC) is that approximately 70% of clinical decisions are based on laboratory test results. It is therefore essential that the results gained from laboratory testing are accurate and reliable in order to provide the appropriate treatment and avoid or prevent potential misdiagnosis.
Patient results are of the utmost importance for a laboratory and therefore running the best Quality Control material should be at the top of their agenda. QC material should have a number of features that allow a lab to judge the overall quality of their output. These features include the controls ability to be commutable (which means how well it reacts as a replicate of a patient sample), is it a true third party control that has been manufactured to provide an independent and unbiased assessment of performance, does your control come with clinically relevant levels and does it have a long shelf life as well as a good open vial or reconstituted stability? These are the questions lab staff will be asking themselves when deciding on what QC is the right QC.
So stay off Santa’s naughty list by providing accurate and reliable patient test results, do this by employing Randox QC in your laboratory. Our controls have been designed to deliver significant cost savings without sacrificing on quality. With consolidated controls (combining up to 100 analytes in a single vial) your lab can reduce QC costs and preparation time, the inclusion of analytes present at clinical decision levels will eradicate the need for additional controls and because of our long shelf life (2 years for liquid controls, 4 years for lyophilised) and excellent stability claims your laboratory can be sure that expensive lot changes will be a thing of the past! Our controls can be described as true third party and this, combined with the commutable nature of the controls, leads to us being able to claim that we have the best Quality Control material around.
So this Christmas when deciding what QC to choose – make sure you look no further than Randox Quality Control. Our QC family is known as Acusera and our product offering includes QC and calibrator material, Interlaboratory Data Management Program (Acusera 24.7), the world’s largest international EQA/PT scheme better known as RIQAS and the newest addition to the family, Linearity or Calibration Verification material.
We have packages for every lab regardless of size and budget and we guarantee you will become ho-ho-hooked on Randox QC.
Wishing you all season’s greetings and a prosperous New Year from everyone at Randox QC.
An important consideration when choosing your Quality Control material that is often overlooked is the shelf life of the control. With every new lot of control extensive validation studies must be performed. Regulatory bodies such as CLIA require new lot numbers to be evaluated before routine use in the laboratory. For example, CLIA has instructed that any new control lot to be run alongside patient samples will need to be verified alongside the old lot of control. The process is designed to give laboratory professionals confidence in the new material and ensure it is fit for purpose before implementing it in the lab.
As part of the validation process laboratories are required to assay both the old and new lots side by side. The current lot is then used to help verify if the new lot will be acceptable to run within the lab. Such validation studies can be very costly for a lab as well as being extremely time consuming – with some studies taking up to a month to complete! By choosing a control with a longer shelf life laboratories can aim to use the same lot of control for a longer time period. Ultimately this means fewer lot changes and minimal inconvenience for the lab. With a shelf life of 2 years for liquid controls and up to 4 years for lyophilised, coupled with unrivalled stability claims, employing Randox Quality Control in your laboratory will ensure that expensive lot changes will be a thing of the past. Our comprehensive control offering is guaranteed to increase efficiency and reduce costs in any laboratory without compromising on quality.

Quality control has recently become crucial in the Point-of-Care (POC) field due to the introduction of ISO 22870 regulations and increased focus in patient safety. Quality control is critical in reducing turnaround time and saving money.
There is now an international standard specifically for POC testing, ISO 22870. This standard is intended to be used in conjunction with the standard for medical laboratories, ISO 15189. This means that aspects relating to Point-of-Care such as training, competence and documentation should be carefully planned, implemented and governed by a quality management system and there is a requirement for QC and EQA to be performed, where available.
POCT is typically carried out by non-laboratory staff, therefore when selecting the appropriate IQC material for POCT there are a number of key characteristics you must consider;
- Format of the material – QC material employed should be liquid stable, requiring no preparation, reducing the likelihood of human error and increasing convenience.
- Value assignment – all values must be accurately assigned. Look out for suppliers who use a large number of independent labs to determine the target value.
- Third party controls – manufactured independently from any specific instrument or method third party controls are designed to deliver unbiased performance assessment.
- Storage – for convenience controls should be liquid stable, as these can be easily stored in a fridge at 2oC – 8oC and won’t need to be shipped on dry ice.
- Stability – a control with a good open vial stability will mean that it can be used for longer with less waste produced, meaning it is more convenient for the medical professional to use.
- Transportation– the liquid stable controls can be conveniently stored at 2oC – 8oC reducing the need to ship on dry ice
- Minimal training– easy to use with little training required, therefore suitable for use by non-laboratory personnel
In addition to IQC, External Quality Assessment (EQA) must also be employed to ensure a comprehensive review of test system performance. It is best to select a programme that offers frequent reporting with a large database of users. This will enable rapid error identification and ultimately accurate and reliable patient testing.
Our Acusera liquid ready-to-use controls include:
- Blood Gas Control– A liquid stable control provided in easy to open ampoules for added convenience and ease-of-use. Assayed, method specific target values are provided for the most common blood gas instruments.
- Liquid Cardiac Control– This is a highly convenient liquid stable cardiac control offering excellent consistency. Assayed, instrument specific target values are provided for 8 cardiac markers, enabling flexibility and consolidation.
- Liquid Urinalysis Control– Liquid control that is compatible for use with both manual and automated methods of dipstick analysis. Available in convenient 12ml vials or 25ml dropper bottles with assayed ranges provided for 13 parameters covering the chemical examination of urine specimens.
- Liquid HbA1c Control– This is another highly convenient liquid ready-to-use control. With an open vial stability of 30 days, keeping waste and costs to a minimum.
Complementary EQA programmes are also available to meet the needs of ISO 22870.
IQCP stands for Individualized Quality Control Plan, and it is an all-inclusive approach to creating a customized quality control plan for a laboratory.
IQCP focuses on assuring quality in the lab using more in-depth means than simply carrying out a certain number of QC tests at a specific frequency. Many different aspects of laboratory operations will be evaluated, such as the test system, reagents, environment, testing personnel etc.
As of January 2016, many labs in and outside the USA have implemented their IQCP’s, but what impact has this had on day-to-day operations?
In order to gauge the overall effectiveness and user-experience of implementing IQCP, Westgard QC1 conducted a survey for all IQCP participants both in the USA and globally.
Opinions were mixed regarding the effectiveness of IQCP:
- Some users found that IQCP decreased the number of QC materials required
- There is a greater emphasis on the pre and post-analytic phases of testing, thus improving process error identification
- Over half of global survey participants revealed that their IQCP identified unacceptable risk(s) in their test system, thereby creating a more robust process
- Of the labs whose IQCP’s were inspected in the USA, 96.3% were deemed adequate by the relevant regulatory bodyies
- Identification of errors can lead to additional personnel training, thereby increasing the knowledge and expertise of laboratory staff
- Due to the length of time taken to create a single IQCP, coupled with the additional expense, several survey participants found that the benefits of IQCP did not justify using so many resources in its implementation
- Many labs raised concerns regarding the availability of guidance in developing an IQCP. Participants complained that useful guidelines were not provided quickly enough, and labs had to rush their IQCP implementation.
- Several survey participants felt as though there was widespread confusion over IQCP. Participants highlighted that the volume of questions from laboratory professionals proves that IQCP was not introduced by regulatory bodies in an organized or effective manner
- Some labs surveyed voiced the opinion that IQCP evaluation needs to be more standardized, and that inspections can either be too lenient or too stringent.
As with any new system, feedback is important for further refinement. IQCP appears to be a step in the right direction for the advancement of laboratory QC. According to Westgard’s survey1, only around 30% of US respondents were satisfied, showing that labs still feel improvements need to be made. Inspectoral standardization, or more concise, straightforward guidelines on IQCP implementation could be potential improvements for regulatory bodies to consider.

Don’t Get Tricked This Halloween – Treat Your Lab to Randox True Third Party Controls Today!
Halloween – a celebration observed by many countries around the world on a yearly basis. Falling on October 31st this holiday is a chance for people to dress up, carve pumpkins, bob for apples, attend costume parties, trick-or-treat and tell scary stories.
It just so happens that we have a scary story for you – and what makes this story even scarier is that it’s a true story!
Our story starts off in a medical laboratory. This laboratory was running QC on their machine as they would do every day. Getting accurate results with no faults or problems arising from their machine, this laboratory was happy with how things were going – until one day when it all went wrong!
Having run their EQA/PT samples, the laboratory found themselves reviewing their report with shock –they noticed a large negative bias. To their horror the perceived ‘accuracy’ they had once achieved was now no longer the case. Right away the laboratory professional’s thoughts turned to the fact that approx. 70% of all clinical decisions are based on laboratory test results, meaning it is essential that the results provided are accurate and reliable in order to prevent potential misdiagnosis or inappropriate treatment. Had they sent incorrect patient results to the clinicians? Had a patient been misdiagnosed? Many thoughts fluttered around in their heads.
The laboratory repeated their QC and found that the results obtained were almost identical to the previous run. The laboratory knew there must be a problem with their QC or their instrument, so they began the troubleshooting process. Nothing. Nada. Zilch. “What was going on?” was the question on the lips of the laboratory professionals.
One of the laboratory professionals then stumbled across a case study that took place in the University of Verona and Academic Hospital of Parma, Italy. The study was related to a field recall of Intact PTH, the reagent was recalled after falsely elevated patient results were discovered. The alarming thing was that the same elevated performance was not identified by the instrument manufacturer’s control. The study reported that due to this issue there was potential for 40,000 inaccurate patient results from just 18 labs in the Lombardy region of Italy. The study also concluded that the issue could have been prevented if a third-party control, independent from calibrator materials had been used.
This PTH case study got the laboratory thinking that maybe they should source a true third party manufacturer… Having sampled a third party QC, the lab found their results now mirrored that of their EQA and patient samples and as such proceeded to make the switch from first party to third party.
The moral of this story is that first party controls can sometimes “trick” the lab into thinking their performance is acceptable. Quite often target values provided with first party quality controls are in the middle of the analytical range thus masking the issues at the low and high ends of the assay range. Laboratory professionals should “treat” their labs to the best QC material. ISO 15189 highlights that the “use of independent third party control materials should be considered, either instead of, or in addition to, any control materials supplied by the reagent or instrument manufacturer”. So this Halloween don’t randomly choose your QC supplier, treat your laboratory to the best, Randox QC.
All Randox controls are manufactured independently of any instrument or reagent, and designed for use with multiple instruments and methods ensuring, unbiased performance assessment.
Following recommendations from recognized institutions such as ISO and CLIA, more laboratories are using third party controls than ever before. However, great care should be taken when choosing which third party control to use. A number of factors should be considered, and primarily among these is whether the control challenges the complete Clinical Range and the Medical Decision Levels. ISO 15189:2012 states that ‘The laboratory should choose concentrations of control materials wherever possible, especially at or near clinical decision values, which ensure the validity of decisions made’.
Measuring the Complete Clinical Range
It is important to assess the full clinical range of an assay i.e. the range between the lowest and highest results which can be reliably reported. In order to make sure a laboratory instrument is working across the full clinical range, a QC which covers low, normal and elevated concentrations must be used.
Question: “If the full clinical range isn’t covered by QC, how will we know whether patient results which fall outside the range of quality controls are accurately reported?”
What are Medical Decision Levels?
Medical Decision Levels (MDL) are the analyte values at which medical professionals can determine whether a patient may be suffering from a certain condition. The MDL is determined by a consensus of medical professionals and clinical research. Patients’ test results are compared to the MDL and appropriate diagnoses or medical interventions can be made.
For example, the MDL of Glucose can indicate a certain diabetic status:
|Analyte||Medical Decision Level||Diagnostic Status|
|Glucose (fasting)||<100 mg/dL||Non-Diabetic|
Many QC manufacturers ‘cut corners’ in an attempt to keep costs down, which often results in the sale of controls which do not cover the complete clinical range or vital medical decision levels. Below is an example of the Glucose concentrations present in a competitor control:
Competitor Chemistry Control Level 1 – 68 mg/dL
Competitor Chemistry Control Level 2 – 134 mg/dL
Competitor Chemistry Control Level 3 – 386 mg/dL
In the examples above, the competitor’s level 1 control covers the non-diabetic MDL, but the level 2 control is not within the ‘Pre-Diabetic’ decision range. The level 3 control is also much higher than can be expected for an elevated diabetic patient result (200 mg/dL or more).
Due to the superior manufacturing process used by Randox, QC target values are consistently within the MDL of tests. For example, the Glucose concentrations present in our Liquid Assayed Chemistry Premium Plus control are:
Level 1 – 57 mg/dL
Level 2 – 114 mg/dL
Level 3 – 236 mg/dL
The MDL for Glucose is covered by the Randox control, meaning laboratory professionals can be confident that patient results will be accurately interpreted.
Immunoassay Medical Decision Levels
Controls which cover the MDL can reduce the number of Quality Controls required by laboratories. For example, Randox Acusera Lyophilised Immunoassay Controls contain particularly low levels of TSH, Ferritin and Vitamin B12 in the Level 1 control, eliminating the need for an additional control at extra expense:
|Analyte||Medical Decision Level||Randox Level 1 IA Control||Competitor Level 1 IA Control|
|TSH||0.1 or 0.27 uU/mL||0.15uU/mL||0.37 uU/mL|
|Vitamin B12||190 pmol/L||174 pmol/L||327 pmol/L|
|Ferritin||12 ng/mL||11.1 ng/mL||49.6 ng/mL|
In this example the competitor offers an anaemia control with lower levels of TSH, Vitamin B12 and Ferritin at an additional cost. With Randox Acusera QC, only one control is required for anemia monitoring and detection.
Six Sigma is a method of process improvement which focuses on minimizing variability in process outputs. The Six Sigma model was developed by Motorola in 1986, and Motorola have reportedly saved over $17 Billion due to its successful implementation.
The model looks at the number of standard deviations (SD) or ‘sigmas’ that fit within the quality specifications of the process. In the laboratory, the quality specifications relate to the Total Allowable Error (TEa). The higher the number of standard deviations that fit between these limits, the higher the sigma score and the more robust the process or method is. As sources of error or variation are removed from a process, the SD becomes smaller and therefore the number of deviations that can fit between the allowable limits is greater; ultimately resulting in a higher sigma score.
A process with a sigma score of six is considered to be a high quality process, making six the target for many industries including the clinical laboratory.
In order to achieve Six Sigma, a process must not produce more than 3.4 defects per million opportunities. In a Laboratory context, this would equate to 3.4 failed QC results per million QC runs.
Sigma is calculated using the following equation:
Sigma = (TEa – %Bias) / %CV
TEa – Total Allowable Error
%Bias – Deviation from the target or peer group mean
%CV – Imprecision of the data
Why is Six Sigma useful in the laboratory?
Six Sigma can be used to help answer one of the most commonly asked questions in laboratory quality control. How often should I run QC?
The Six Sigma model allows laboratories to evaluate the effectiveness of their current QC processes. Its most common use is to help implement a risk-based approach to QC, where an optimum QC frequency and multi-rule procedure can be based on the sigma score of the test in question. The performance of tests or methods with a high sigma score of six or more may be evaluated with one QC run (of each level) and a single 1:3s warning rule. On the other hand, tests or methods with a lower sigma score should be evaluated more frequently with multiple levels of QC and a multi-rule strategy designed to increase identification of errors and reduce false rejections.
The below table shows how multi-rules and QC frequency can be applied according to Sigma Metrics:
|Sigma Score||QC Frequency||Number of QC Samples||QC Rules|
|6 or more||Once per day||Each level of QC||1:3s|
|5||Once per day||Each level of QC||Multi-rule strategy|
|4||At least twice per day||Each level of QC||Multi-rule strategy|
|< 4||At least four times per day||Each level of QC||Multi-rule strategy|
It is important to note that this is just an example and it may be necessary to run QC samples more often than three times per day. Some high throughput laboratories prefer to run QC samples before and after a set number of patient samples, while others opt to run QC samples after a set period of time. Whatever frequency you choose it is vital that the frequency is appropriate for the test in use. Download our guide ‘How often is right for QC’ to find out more.

Results of our Liquid vs Lyophilised Poll
Having conducted a recent poll on our Social Media platforms (Facebook, LinkedIn & Twitter) asking our customers what format they preferred their quality control material in – liquid or lyophilised – we saw a large preference for liquid controls.
What does this poll result really tell us?
That most people prefer Liquid controls? Yes.
Lyophilised controls are not as popular amongst our social following? Yes.
However, it also tells us that even though most people chose a liquid format there was still almost a quarter of people who prefer to use lyophilised controls. Liquid and lyophilised controls both have their advantages and disadvantages, this blog is designed to help you decide which is the best fit for your lab.
Firstly, it is important to note that there are two distinct types of liquid control available on the market;Liquid ready-to-use and Liquid for ease-of-use, better known as Liquid Frozen. Both types of liquid controls reduce the potential for reconstitution errors and prevent contamination from poor quality water.
Liquid frozen controls must be thawed in a refrigerator before use, making them a little less convenient than the liquid ready-to-use alternative. They require no reconstitution so associated errors are removed. Due to the frozen nature of these controls, they are often shipped on dry ice to prevent thawing in transit, as such transportation costs can be significant.
Liquid ready-to-use controls are arguably the most favoured of the three formats and it is easy to understand why. The controls are simple to use, they require no preparation and there is no need to thaw before use.– With zero preparation required, these controls can be removed from the packaging and used right away! What’s more, they can be conveniently stored at 2-8oC minimising expensive shipping costs.
Another major benefit of using a liquid ready-to-use control is the fact that they are ideal for POCT (Point of Care Testing). The ability to use these controls on the spot is extremely beneficial to POC providers.
Lastly, the choice of 22% of respondents – lyophilised. This is freeze dried material which requires the laboratory professional to reconstitute the sample using sterilised water and mixing before use. Although this format is not as easy to use as either liquid control it does come with benefits. The enhanced stability of this control sees a shelf life of almost double the two years that is normal with a liquid control, however, the potential for reconstitution errors and the fact it is not as simple to use lead to the majority of people opting for a more convenient liquid control.
Randox Quality Control Range
With Randox QC there are a vast array of controls available in liquid ready-to-use and liquid frozen formats. Areas we have liquid frozen formats available in, include; Clinical Chemistry and Immunoassay.
Liquid ready-to-use controls can be found in the following; Liquid Cardiac, Blood Gas, Liquid Urine, Urinalysis, Specific Protein, Ammonia Ethanol, Haematology, Liquid HbA1c and Liquid Tumour Markers.

“In Vitro Diagnostics (IVD) Quality Controls Market” recently published by Markets and Markets has highlighted an overall significant growth within the Quality Control Market. Further growth is anticipated in the coming years with the Markets and Markets report estimating that the IVD QC market will be worth $979 million.
One area that is currently experiencing growth within this sector is the EQA segment, which Markets and Markets estimates to command a 6.6% share of the overall IVD market. The report is crediting growth within this segment to you, the customer, stating “…various end users or customers of IVD quality control products mostly prefer external support to run their quality control activities. For this, market players are largely focusing on providing external quality assurance (EQA) support”. As such companies such as Randox are being approached to provide EQA for a range of small, independent laboratories and large laboratory chains alike.
What other factors have contributed to this growth?
The adoption of ISO15189 and other similar standards is becoming mandatory in many countries, as discussed in a previous blog post. Accreditation highlights the accuracy and reliability of the patient results being released. ISO15189 states that “The laboratory shall participate in interlaboratory comparisons such as those organised by external quality assessment or proficiency testing schemes”. Therefore laboratory managers are employing EQA programmes in their laboratory to meet such requirements. EQA also enables laboratories to meet other accreditation requirements such as peer comparison and clinically relevant testing.
Selecting the right EQA for you
When selecting the right EQA scheme for your laboratory there are a number of considerations to be made; sample frequency, peer group numbers, report format, report turnaround and so on. According to a survey conducted by Randox Quality Control 55% of respondents listed sample frequency as the most important feature to be considered when selecting an EQA scheme. Sample frequency is an ongoing debate regarding EQA. However, schemes with frequent reporting will allow you to easily pinpoint when an error occurred and implement corrective actions with minimal disruption. Also making the top three key factors in this survey were; quality samples and peer group numbers.
What can Randox Quality Control offer?
As the largest international EQA scheme available on the market RIQAS offers laboratories around the world assurance that the results they are releasing are accurate and reliable.
