As the best it’s field, the Randox VeraSTAT device allows athletes to overcome the limitations of other generation tests, providing accurate, cost effective and reliable results that will help users receive the care necessary to get them back on their feet and back to their best.
Monitoring response to exercise is vitally important to an athlete and trainer. While a heavy training schedule can lead to chronic immunosuppression in athletes, it is essential that they receive the appropriate care in the case of a dip in health state. Eliminating the risk of inflammation and infection is essential to preventing disruptions to practice and performance.
VeraSTAT Test Menu
The VeraSTAT testing menu is designed to monitor an athletes immune response to exercise. C-Reactive Protein (CRP) levels are used to guide the treatment of bacterial infections or inflammation associated with tissue injury and other inflammatory disorders. On the other hand, Mxyovirus Resistance Protein 1 (MxA) is used as a key indicator of viral infections. These tests used in combination, can allow healthcare clinicians to determine the best course of treatment and get the athlete back to full health
C-Reactive Protein (CRP)
CRP is a Key indicator of inflammation and stress, often resulting from the breakdown in tissues. Overtraining can lead to elevated levels of CRP in the body.
Myxovirus Resistance Protein I (MxA)
MxA is a key indicator of a viral infection which may impact physical performance and activity levels. Unexplained failures are often attributed to recent or current infections.

Quality assurance is an essential aspect of any clinical/diagnostic testing service and is aimed at ensuring the accuracy and reliability of patients’ results. The right result allows the right clinical advice to be offered in a timely manner. Quality assurance operates at two levels:Internal Quality Control
Internal Quality Control includes operator training/ competency assessment, analyser/ test system maintenance, and adherence to policies/ processes. Whilst some point of care analysers include inbuilt quality checks, cross-check analysis against samples with known levels provides immediate assurance and evidence that a patient’s result is safe to report.External Quality Assessment
External Quality Assessment involves analysis of samples with unknown levels that have been distributed by an external organisation. Participants are informed how their results compare with other participants, hence providing independent evidence of performance. Increasingly, participation in an external quality assessment scheme is becoming a mandatory requirement where health and healthcare services are being provided.

Point of Care Testing (POCT) Explained
Point of Care Testing (POCT) is the delivery of a test at the point in time at which the result will be used to make a decision and taking appropriate action resulting in an improved health outcome. It is also known as near patient, bed-side, extra-laboratory, decentralised, and ancillary testing [1]. It has been shown to reduce hospital stay time, reduce complications, and improve adherence to treatment [2].
Point of care testing is not a recent practice; many early diagnostic tests were administered at the bedside. However, analytical technology has progressed and multiple tests can be performed within minutes in a laboratory. Recently, this technology has been put into the hands of the staff near the patients [2]. There are two types of technology, benchtop analysers and hand held devices. Bench top systems are just smaller versions of laboratory analysers but some steps are automated. Hand held devices are simple in appearance but complex internally, they can manage several tasks including, adding reagents, separating cells from plasma, and reading colour or other measures.
Results can be obtained faster, allowing for more immediate decisions meaning treatment can begin sooner. Patients can live a longer and higher quality life, helped by a reduction in the length of hospital stays.
Some benefits of POCT [2]:
Key objective
The main objective of Point of Care Testing is to generate results more quickly so that appropriate treatment can be provided, resulting in an improved patient outcome.
Management
Accurate and reliable results can only be obtained if the patient and sample are treated correctly. Point of care testing is likely to be performed by staff with a limited technical background, so training and quality control are vital.
Outcomes
Proper analysis technique alone is not enough to ensure an accurate decision; any test will only be beneficial if the appropriate action is taken based on the result. The effectiveness of POCT is assessed in terms of the overall outcome of the patient.
There are three phases in the POCT cycle: pre-analytical phase, analytical phase, and post-analytical phase. About 90% of quality issues are attributed to the pre-analytical and post-analytical phases [3]. These errors are mainly attributed to user error and can be caused by a number of issues including, selecting the wrong POCT device, not following manufacturer instructions, inadequate training, not adhering to appropriate QC practices, and many more.
The errors can usually be mitigated by implementing an action plan and ensuring it is executed exactly as designed, deviation from the action plan will lead to errors. Errors in POCT diagnostics can lead to misdiagnosis, improper treatment, costly follow-up procedures, and death.
Some strategies for improvement:
Internal Quality Control and External Quality Assessment is conducted to monitor the stability of the analytical measurement system and to alert the operator to a change that may lead to a medically significant error [6].
A study by Price, Smith and Bruel [8] was conducted on a number of labs over a period of time of up to 15 years. They discovered that test result performance improved with time and was associated with regular participation in External Quality Assessment (EQA) schemes and with the use of internal quality control (IQC) procedures.
Internal Quality Control
Internal Quality Control (IQC) is used to assess the day-to-day consistency of assay performance, providing quality assurance for patient results. IQC activities are among the ten most common POCT deficiencies. These may include performing and documenting quality control testing and taking the correct action for outliers [4]. This poor performance could be attributed to how IQC is viewed in POCT; users may lack appreciation of the potential for errors and may see the analyser as infallible, they likely see IQC as an additional workload as opposed to part of their testing routine.
CLSI regulations require risk assessment for each stage of patient testing alongside an implementation of a quality control plan. Below are some suggestions for how IQC should be conducted for POCT.
Conduct
IQC should be conducted when: a new lot of consumable is used; a patient result is queried; after maintenance; the device has been physically insulted. IQC should be conducted by the usual device operator so assurance can be provided for the whole testing process.
Training
ISO 22870 requires POCT users should be trained in the theory and practice of IQC [5]. Staff should be trained in every aspect of POCT including storage, preparation, frequency, documentation and basic troubleshooting.
Material
QC material for POCT should be obtained from a third party provider and not rely on material provided by the device manufacturer, the benefits of which are well documented. It should also contain analytes at clinically relevant concentrations, be provided ready-to-use, and be stable at ambient temperatures.
Results
All IQC results must be recorded with the date, time, user, decision to accept or reject, and any actions taken as appropriate. Locally assigned ranges alongside analyte-specific rules should be used to maximise error detection. An example of how IQC could be recorded and an action flowchart can be seen in Fig. A below.
Troubleshooting
There should be a protocol for required actions following a failed IQC. Any troubleshooting should be developed with knowledge of the most common errors and user capability.
Review
A monthly review should be conducted to identify persistent failures and trends.
The cost of IQC may also be a factor in resistance to IQC, however, while it is difficult to quantify, the cost of not conducting it may be greater in terms of human harm. A whitepaper is available detailing IQC in POCT (download).

External Quality Assessment
External Quality Assessment (EQA) or Proficiency Testing (PT) involves running blind patient-like samples and comparing your results to peer results, in order to retrospectively monitor the accuracy of reporting. EQA samples should be treated as if they were a patient sample and therefore must be run by personnel who would normally use the device. This provides confidence in the reliability of patient test results. (Learn more about EQA)
Benefits of participation in an EQA programme include assessment of result accuracy, assessment over time, comparisons with instruments, methods and peers, and providing confidence in test results.
EQA for POCT is, in theory, similar to EQA in a large laboratory. There is a significant difference however, the POCT participants are usually health care professionals with little knowledge of laboratory medicine. A lack of understanding of the importance of EQA had led to a smaller percentage of sites participating than large laboratories.
A Good EQA Scheme
A good EQA scheme should offer:
Conducting EQA in POCT
Below are some suggestions for how EQA should be conducted for POCT.
Conduct
EQA should be conducted by the operator who normally conducts patient testing to ensure the true workflow is assessed [6].
Material
EQA samples should be commutable, meaning they have the same numeric relationship between measurements procedures as is observed for a panel of patient samples (reacts the same as a real patient sample).
Report Frequency
Challenges / surveys should be frequent enough to identify systematic errors in a timely manner, affecting the fewest patient results [10].
Report Turnaround
A fast turnaround time allows test system errors to be identified sooner and necessary corrective actions to be taken immediately with minimum disruption to the lab.
Review
A regular review of past EQA results should be part of the cycle of quality.
Guidance
A POCT EQA provider should be able to provide assistance when the user is having difficulties.
Results
Individuals carrying out testing should have the correct knowledge to interpret results, choosing a scheme with easy to interpret results can help.

Importance of External Quality Assessment (EQA)
External Quality Assessment (EQA) / Proficiency Testing (PT) allows for a comparison of a laboratory’s testing procedures to other laboratories across the world. Comparisons can be made to a peer group of laboratories or to a reference laboratory.
EQA involves running blind patient-like samples, comparing your results to peer results, in order to retrospectively monitor the accuracy of reporting. EQA samples should be treated as if they were a patient sample and therefore must be run by personnel who would normally use the device. This provides confidence in the reliability of patient test results.
Participating in an EQA scheme allows a laboratory to gather valuable data, this data can be used in a variety of ways [1]:
EQA provides assurance to both staff and customers that testing taking place at your laboratory provides accurate and reliable results. Problems can be identified early on and corrective action can be untaken. The reliability of methods, materials, and equipment can be evaluated and training can be developed and its impact monitored.
Large laboratory groups can compare their performance with sites across their group, ensuring accuracy and consistency no matter where testing takes place.
EQA participation is often a requirement for accreditation, gaining accreditation alone has a host of benefits, not least an increased confidence in results from customers, current and potential.
Read more about accreditation: ‘The Importance of Meeting ISO 15189 Requirements’.
Point of care testing (POCT) refers to testing that is performed near or at the site of a patient with the result leading to a possible change in the care of the patient. The popularity and demand for POCT has recently seen rapid growth, this comes from the advantages including the added convenience of being able to obtain a rapid result at the patient’s bedside, thus allowing immediate action, saving time and improving the potential outcome for the patient.
Although there are many benefits of using POCT devices in terms of their convenience, these benefits are only true if the results produced are both accurate and reliable. Ensuring accuracy and reliability is the primary responsibility of Quality Control.
EQA is strongly recommended for all point of care devices and is recommended by ISO 22870, which providesspecific requirements applicable to point-of-care testing and is intended to be used in conjunction with ISO 15189.
There are many External Quality Control schemes that come in different varieties. EQA schemes can be mandatory, required either by accreditation or law. Others are voluntary and carried out by laboratories who want to ensure that they are carrying out accurate testing and improve the quality of the lab’s performance [1].
A good EQA scheme should offer:
EQA is a great tool for comparing against a peer group and maintaining an effective QC strategy, however, it has its limitations.
EQA / PT alone cannot provide a complete evaluation alone; it is important to also run third party controls regularly. You can find out about the importance of third party controls here.
EQA results can also be affected by variables not relating to patient samples, including preparation, clerical functions, matrix effects, and selection of method. The errors can appear to be a downside to EQA but it can be used as a way to evaluate staff performance as well as assay performance.
If possible, every laboratory should participate in an EQA scheme that covers all testing procedures. Laboratories need to develop a management process with the objective to assure that EQA samples are treated appropriately and in the same manner. This includes, sample handling, sample analysis, record keeping, investigating deficiencies, taking corrective actions, and communicating results with laboratory staff and management.
Problems at any stage of sample analysis can cause errors, when an error does happen, all elements of the process need to be checked. Some examples of errors:
Pre Analysis
• Incorrect sample handling during preparation, shipping or storage
• Improper storage
• The material has expired
• An error in manufacturing
Analysis
• Instrument, calibration or reagent defects
• Staff competency
• Matrix effects
• Incorrect analysis method
Post Analysis
• Report misinterpretation
• Clerical or transcription errors
• Failure to take corrective action
• Where possible, all laboratories should participate in an EQA scheme for all tests that they perform.
• EQA samples should be treated in the same way as a patient sample, using the same procedures, instruments, methods, and staff who normally perform the testing.
• EQA provides valuable resources and data to effectively maintain accurate and reliable results and should be seen as educational.

ISO 22870:2006 in the Point-of-Care Testing (POCT) Market
Point-of-Care Testing (POCT)
The Point-of-Care testing market, better known as POCT, is growing rapidly as the demand for faster patient testing increases. This point is fully backed up through the results of the recent BIVDA (British IN-Vitro Diagnostics Association) survey of 2016. This survey focuses primarily on Point-of-Care Testing and there were a few questions asked that sparked an interest amongst us. The questions can be seen below;
“What are the challenges you face regarding POCT?”
“What do you see in the future for POCT?” (BIVDA, 2016)
Although many answers were put forward there was one (answer) that appeared for both questions. Accreditation. We found this intriguing yet far from surprising. POCT and accreditation go hand-in-hand, with laboratories striving to achieve ISO accreditation with the ultimate aim of allowing patients to have peace of mind that they are being tested properly and effectively.
ISO 22870:2006
The ISO standard that relates to POCT is ISO 22870:2006 Point of Care Testing- Requirements for quality and competence. This standard gives specific requirements applicable to POCT testing and apply when POCT is carried out in a hospital, clinic or a healthcare organisation providing ambulatory care. However, it is important to note and remember that ISO 22870 is not to be seen as a separate, standalone document, in fact, it is to be used in conjunction with ISO 15189:2012 (medical laboratories – particular requirements for quality & competence).
With accreditation in POCT becoming a major factor to laboratories, it is no surprise to see accreditation as one of the top answers to the two questions asked in the survey.
For laboratories looking to participate in point-of-care testing there are other factors of ISO 22870 that they must be aware of, one of the major factors is as follows;
“ISO 22870:2006 advises that where available, Internal Quality Control and participation in an External Quality Assessment (EQA) scheme is required in the point-of-care setting.”
How can Randox help?
Fortunately for laboratories, Randox are able to help out here. With a vast range of true third party controls and 32 comprehensive RIQAS (EQA) programmes, Randox can aid laboratories as they aim for ISO accreditation.
We have multiple products particularly suited to the POCT market including, Liquid Cardiac, Blood Gas and Urinalysis. These products are available both as internal quality controls and as EQA programmes.
Our Acusera range of true third party controls are conveniently supplied liquid ready-to-use, therefore requiring no preparation. This is a particular advantage in the POC environment were test results are required quickly and also were testing is not always performed by laboratory personnel. Supplied with assayed target values and manufactured from 100% human material, ensuring they act in the same manner as a patient sample, our Acusera controls are ideal for use at the point of care and will therefore aid a laboratory in gaining ISO accreditation.
Similarly, participation in our RIQAS EQA programme will also assist laboratories to meet regulatory requirements and achieve ISO accreditation. With over 40,000 laboratory participants in 123 countries, RIQAS is the largest international EQA scheme worldwide! Our Liquid Cardiac, Blood Gas and Urinalysis programmes are all supplied liquid ready-to-use, complementing their Acusera counterparts perfectly!
By using our Acusera controls and RIQAS EQA programmes side by side, a laboratory can confidently aim for ISO accreditation in the knowledge that they are meeting criteria.
