The Evidence Investigator is a compact, semi-automated benchtop analyser which is renowned for its versatility, robustness and effective reporting methods. The Evidence Investigator has offered efficient and comprehensive testing in a wide range of laboratory settings for many years including, clinical diagnostics, molecular, research, toxicology and food diagnostics.
The Evidence Investigator is the perfect fit for medium throughput laboratories seeking maximum use of bench space and can process up to 44 results from a single sample, with a maximum throughput of up to 2376 tests per hour.
It is extremely well equipped to provide reliable and accurate results because results are generated using Charge Coupled Device (CCD) camera, which quantifies chemiluminescent light. The light then measures the degree of binding between the sample and specific biochip bound ligands. The Evidence Investigator image processing software translates light signal generated from chemiluminescent reactions into analyte concentrations which removes the need for any manual processing of data.
Our molecular product range offers diagnostic, prognostic and predictive solutions across a variety of disease areas including sexually transmitted infection (STI), respiratory tract infection, colorectal cancer, familial hypercholesterolemia (FH) and cardiovascular disease (CVD). Additionally, we can provide a wide range of assay formats including single nucleotide polymorphisms (SNP) genotyping, pathogen detection and mutation detection. The technology allows simultaneous detection of multiple analytes from a single sample for efficient and cost-effective testing.
STI and Respiratory Arrays
Sexually transmitted infections (STIs) affect more than 1 million people every day and each year 500 million new cases of STIs occur.1 Therefore, it is vital for early and accurate detection. Randox’s Sexually Transmitted Infections Multiplex Array simultaneously detects 10 bacterial, viral and protozoan including primary, secondary and asymptomatic co-infection for a complete infection profile. The assay is based on a combination of multiplex PCR and biochip array hybridisation. Innovative PCR priming technology permits high discrimination between multiple targets.
Respiratory tract infections are caused by many viral and bacterial pathogens and are the second most common cause of morbidity and mortality worldwide.2 The Respiratory Multiplex Array is the most comprehensive screening test for infections of both the upper and lower respiratory tracts, simultaneously detecting 22 bacterial and viral pathogens from a single sputum lavage or nasopharyngeal sample.
Both arrays detect the most common and frequently requested infections in sexual and respiratory health. These comprehensive, highly sensitive and specific tests enable identification of co-infections simultaneously, often in asymptomatic patients and enable antibiotic stewardship.
KRAS, BRAF, PIK3CA Array and Familial Hypercholesterolemia Arrays I & II
The colorectal cancer (CRC) is the third most common cancer worldwide. Overall, the lifetime risk of developing colorectal cancer is: about 1 in 22 (4.49%) for men and 1 in 24 (4.15%) for women.3 The KRAS, BRAF, PIK3CA Array simultaneously detects 20 point mutations within the KRAS, BRAF and PIK3CA genes. The assay is validated for use with the DNA extracted from fresh/frozen and formalin fixed paraffin embedded tissue. The array is CE marked for routine clinical use.
Familial Hypercholesterolemia (FH) is a genetic disorder of lipoprotein metabolism. 4It is the most common autosomal dominant, or inherited disease and affects the plasma clearance of LDL-cholesterol, resulting in premature onset of cardiovascular disease and higher mortality risk.5 Early diagnosis is crucial as by the time the FH sufferer enters early adulthood they will have accumulated >20 years of continuous exposure to build up of fatty or lipid masses in the arterial walls and are at the hundred-fold greater risk of a heart attack than other young people. The Familial Hypercholesterolemia (FH) Arrays I & II are rapid, simple and accurate detection of 40 FH-causing mutations within the LDLR ApoB and PCSK9 genes.
These unique biochip assays permit high discrimination between multiple targets in several genes with a rapid turnaround time (3 hours). The arrays enable detection of the most frequently occurring mutations known to cause disease (FH) and adversely affect patient treatment (KRAS, BRAF, PIK3CA). A unique primer set is designed for each target which will hybridise to a complimentary oligo-nucleotide probe spotted on a biochip discrete test region (DTR).
Cardiovascular Risk Prediction Array
Coronary Heart Disease is the leading cause of death in the developed world and its prevention is a core activity for public health systems worldwide.6 Randox have the Cardiac Risk Prediction Array which will allow for 19 SNPs to be genotyped simultaneously, which incorporate a test to identify patients predisposed to statin-induced myopathy.
This array identifies individuals with a genetic predisposition to coronary heart disease (CHD). The innovative multiplex primers are designed to discriminate DNA sequences which differ only at one base.

Randox Testing Services offers high quality drug testing with use of our revolutionary Biochip Array Technology specifically optimised for drugs of abuse testing. This technology allows multiplex back-to-lab testing of different drugs from one sample and offers test consolidation for comprehensive testing at an affordable price.
With a comprehensive drugs of abuse test menu we are able to test for a range of different drugs. Drug testing packages can be customised to include multiple different drugs to test per sample.
Our drug testing methods ensure fast and simple sample collection. We have a variety of non-invasive methods for patient comfort including use of a urine sample, hair strand or oral fluid sample to test for specified drugs. Utilisation of different testing methods also ensures flexibility of drug abuse profiling with the ability to offer short-term drug abuse profiling via oral fluid and urine testing, long-term drug abuse profiling via hair testing or a combination of both.
Oral Fluid Testing
An oral fluid test can detect drugs for up to 48 hours after consumption. Providing analysis of short-term drug abuse, an oral fluid drug test is used by employers conducting for-cause and post-incident testing, as well as medico-legal solicitors who may require testing for abstinence of drugs.
An oral fluid test consists of obtaining a saliva sample from between the cheek and gums to analyse traces of drugs. This sample method is reliable due to the high concentrations of drug components which remain in the oral cavity for a period of time after drug consumption. Sample collection is taken quickly, easily and is non-invasive. The sample collection is also observed which ensures samples are not tampered with.
A urine test offers short-term detection of substance abuse. Alcohol is detectable in urine for less than 12 hours, and a urine drug test can detect traces of drugs from between 4 hours and up to 8 days (this may be extended for regular cannabis users to around 30 days). It is often used in a combination with hair testing to provide an enhanced time-line for drug and alcohol detection; therefore allowing analysis of chronic substance abuse.
As a simple and practical method it is used as the most common sample type for workplace drug and alcohol testing. It is also utilised when conducting family law testing to ensure no alcohol intake by someone who has been forbidden to consume alcohol by a court of law or someone who is on a drugs or alcohol rehabilitation program.
A urine test consists of gaining a urine sample from the individual securely. Due to the nature of the urine sample being deposited privately by the sample donor, measures need to be taken to ensure the sample is not tampered with. At Randox Testing Services samples are collected under strict chain of custody protocols to guarantee sample integrity for legally defensible testing. We also increase accuracy of results by testing for creatinine which is a simple method of testing the authenticity of the sample given and reduces false-negative results giving you confidence in these testing methods.
Hair testing is a long-term substance abuse profiling with a detection window of 90+ days. It is commonly used by recruiters and employers conducting pre-employment screening and is the most common sample type used for substance abuse assessment in child protection and medico-legal cases.
Hair testing involves taking a hair stand sample from an individual to detect if and approximately when someone has consumed drugs or alcohol. A 3cm sample is generally used to obtain a longer analysis of substance abuse.
When a drug is taken it is absorbed into the blood stream and circulated around the body. As a result it is incorporated into the hair follicle meaning that as the hair grows, drugs are transferred into the hair strand. It can take up to 2 weeks for drug components to enter the hair and therefore analysis of a 3cm sample is recommended.
Analysis of the hair strand allows traces of drugs to be detected to provide an overall picture of drug abuse or a month by month analysis. Segmentation of the hair sample to provide a detailed month-on-month view is advantageous as it can highlight trends of drug use and identify periods of abstinence or high level use. Body hair can be used in special circumstances however segmentation into a month by month analysis is not possible.

What is Lyophilisation?
Lyophilisation or ‘freeze drying’ is the process by which water is removed from a product after it is frozen and placed under a vacuum, allowing the ice to change directly from solid to vapor without passing through a liquid phase. The process consists of three separate processes:
- Primary Drying (Sublimation)
- Secondary Drying (Desorption)
There are many benefits to using a lyophilised control including; improved product shelf-life and enhanced stability of volatile analytes. For example, many lyophilised controls have a shelf life of up to four years from the date of manufacture resulting in a reduction of costly new lot validation studies. Furthermore, lyophilised controls can be aliquoted and refrozen to extend the working stability of the product.
Reconstituting Lyophilised QC Material
The process of reconstitution involves adding a specified volume of distilled water to lyophilised QC material. The water should completely dissolve the lyophilised contents, giving a liquid solution, which is ready for analysis.
Reconstitution is a straightforward process, but requires a high level of precision. Small errors can have serious implications to the reconstituted material:
- If too much water is pipetted during reconstitution, the material will be heavily diluted and results will be lower than expected
- If too little water is pipetted during reconstitution, the material will not be sufficiently diluted, and results will be higher than expected
- If the correct volume of water is pipetted, but a small amount of water gets stuck in the pipette tip due to poor pipetting technique, results will be higher than expected
If a lyophilised control has been reconstituted incorrectly the contents of the vial will be wasted. It is therefore vitally important that controls are reconstituted with care.
Materials and Methods Required
The list of requirements for an accurate and consistent reconstitution technique is not extensive, but each requirement is vital. Labs should have:
- Calibrated volumetric pipettes
- Sterile, appropriately sized pipette tips
- Distilled water, or other reconstitution fluid as specified
- Technician with good pipetting technique
- Lyophilised QC stored according to manufacturer’s specifications
How to Reconstitute Lyophilised QC Material
Each different lyophilised control may require slightly different preparation, always refer to the instructions for use before reconstituting control material. The below guide provides a general overview of the reconstitution process, using the Randox Human Assayed Chemistry Premium Plus control (HN1530) as an example
- Place the vial of lyophilised QC on a flat surface, carefully remove the lid and the rubber stopper making sure not to spill any material
- Using a calibrated pipette and sterilised pipette tip, add exactly 5ml of distilled water directly into the QC vial, ensuring no water is left in the pipette tip, or on the rim/side of the vial
- Place the rubber stopper and lid firmly back onto the QC vial, and leave to stand for 30 minutes
- After 30 minutes, gently invert the QC vial 10-15 times to ensure the contents is completely dissolved, making sure to avoid the formation of foam. It is important that you DO NOT SHAKE the vial. Alternatively place the vial on a roller for 30 minutes to ensure the contents is thoroughly mixed
- Once satisfied all material has been completely dissolved, proceed to use the QC product in accordance with the ‘Control’ section of the individual analyser application
- Once finished, refrigerate any unused material. It is good practice to label the vial with the date of reconstitution to prevent the use of material outside of the recommended stability period
- Prior to reusing lyophilised material, mix the contents thoroughly by gentle inversion, as highlighted in Step 4
It is important to remember that there may be slightly different reconstitution requirements for different QC material. For this reason, it is vital that the instructions provided on the QC Kit Inserts are closely followed.
Reconstituting lyophilised QC can be time-consuming. Therefore, Randox Acusera offer convenient 5ml distilled water serum diluent to assist laboratories with reconstitution of lyophilised controls. These user-friendly pour over vials streamline the reconstitution process and eliminate the risk of pipetting errors.
If you have any further questions regarding lyophilised controls or would like to contact us, please do so by emailing us at firstname.lastname@example.org or use the contact us button provided.

Randox Quality Control wish you all Season’s Greetings & a Prosperous New Year!
Some laboratory professionals believe that using Internal Quality Control (IQC) and External Quality Assurance (EQA, also known as Proficiency Testing) material from the same provider can lead to increased levels of qc bias, or that their test system will not be appropriately challenged. It is important to address these concerns, because some labs may in fact be hindering their own performance by using IQC and EQA material from different sources.
It is important to first understand how IQC and EQA work together to help form a complete Laboratory Quality Management System.
IQC and EQA in Laboratory Quality Management
IQC is a means of monitoring test system precision on a daily basis. IQC effectively evaluates test system performance over time, so that any sudden or gradual shifts in performance can be detected. However, while IQC is an effective performance monitor, it cannot detect more intricate problems like calibration errors or wide acceptable limits provided by some QC manufacturers.
EQA is essential for challenging test system accuracy, and is carried out less frequently than IQC testing. EQA samples are tested ‘blind’ and the results are returned to the scheme organiser. As EQA testing compares an individual lab’s performance to other labs using the same method and instrument, it is a very effective tool for identification of potential issues.
Is there any disadvantage to using IQC and EQA material from the same provider?
The answer to this question depends primarily on the source material of the IQC and EQA. If an IQC provider manufactures their material using artificial additives or components of animal origin, then it will not be suitable to use EQA material from the same provider. Westgard (2011) maintains that using non-commutable IQC or EQA material can lead to results becoming compromised due to matrix effects – something which would not happen using commutable controls.
For example, with Immunoassay testing, non-human components of IQC material interact with antibodies in the reagent in a different way to fully human patient samples – ultimately giving unpredictable shifts, and not adhering to the ISO 15189 requirement to: “use quality control materials that react to the examining system in a manner as close as possible to patient samples”.
However, if the IQC and EQA material is manufactured using a source material which is similar in composition to patient samples (100% human), this commutable control will adequately mimic patient sample performance; meaning labs can use EQA and IQC material from the same provider with confidence that the integrity of their results is maintained.
ISO 15189 also states: “Use of independent third party control materials should be considered…”. In this instance, ‘Independent’ does not mean from a separate provider. It means that the QC material should not be optimized for use on one specific instrument (i.e. not dependent on a single instrument/method type).
No regulatory body states a requirement to use different providers for IQC and EQA material. Indeed, using IQC from one provider and EQA from another provider could increase the risk of labs using non-commutable material.
Labs should use commutable IQC and EQA material for a true assessment of their test system. Randox QC and RIQAS EQA are specifically designed with commutability in mind, giving labs a control which reflects patient sample performance and ensures excellent performance.

Got a question?
Randox Quality Control is a world leading manufacturer of third party quality controls. With an extensive product portfolio – including the largest range of liquid ready-to-use controls, Randox QC will meet your laboratory requirements and deliver trustworthy results repeatedly.
What control formats are available for your laboratory?
There are three distinct formats available for use in the laboratory with each format having benefits and drawbacks. When choosing a Quality Control material it is important you choose the most convenient solution for your laboratory requirements. The three formats are;
- Lyophilised (freeze dried)
- Liquid frozen
- Liquid stable (ready-to-use)
What format is best?
There are several possible answers to this question, simply because, every laboratory is different. What works for one laboratory may not work for another and for this reason there is no one format that works best for all laboratories.
What we can say however, is that there are varying levels of convenience across the different formats. The most convenient, and arguably, the most favoured of the three formats is liquid ready-to-use. It is not difficult to understand why this format is widely regarded as the preferred choice of control in laboratories – they are simple to use, require no preparation and can be conveniently stored and shipped at 2-8oC.
Why should you consider a liquid ready-to-use control?
There are many benefits to using a liquid ready-to-use control over both liquid frozen and lyophilised controls. One of the main benefits of a liquid stable control material is that it eliminates any potential reconstitution/pipetting errors often associated with lyophilised controls. They also eliminate the additional time taken to thaw liquid frozen controls and can significantly reduce shipping/delivery costs as they do not need to be shipped on dry ice.
Another major benefit of running a liquid ready-to-use control is the fact they are also suitable for use in Point-of-Care-Testing (POCT). With growing popularity amongst laboratory professionals and more people expecting rapid results, POCT is on the rise. Due to their easy to use nature, liquid ready-to-use controls are extremely beneficial to POCT providers.
One further benefit to using a liquid ready-to-use control is the longer open vial stability when compared to both lyophilised and liquid frozen controls. With many lyophilised and liquid frozen controls, the open vial stability can vary and generally is around 7 days when fully thawed or reconstituted in comparison to 28 days with a liquid ready-to-use control.
