Researching the Evidence Investigator
The Evidence Investigator analyser is based on the award-winning Biochip Array Technology (BAT). Biochip Array Technology is a multi-analyte testing platform allowing the simultaneous quantitative or qualitative detection of a wide range of analytes from a single sample.
The Evidence Investigator is a semi-automated benchtop analyser which is tailored for the areas of research, forensic, clinical, molecular and veterinary testing. The key feature is the fast turn-around time the Evidence Investigator can process up to 44 results from a single sample, with a maximum throughput of up to 2375 tests per hour. The Evidence Investigator saves time because it will carry out multiplex testing which will allow multiple tests to be carried out from a single patient sample which in return will save time and resources. The machine is more suitable for medium throughput laboratories.
The technology offers a wide-ranging and diverse test menu which will benefit the research areas immunology, metabolic, Sport & Exercise, oncology and cardiovascular. Randox Research provides the Evidence Investigator to the five research areas to help their research become more efficient, cost effective and accurate.
Randox works extremely hard with their research and development, over 16% of turnover is reinvested in R&D. The current collaboration Randox works along with are Royal Victoria Hospital, Queen’s University Belfast and Cambridge University.

The key features and benefits of Biochip Array Technology
Biochip Array Technology
In 1992, Randox invested £180 million to create and introduce Biochip Array Technology (BAT) which converted laboratory testing. Randox came up with the innovation by recognising the major problem with traditional diagnosis. Within traditional diagnosis several tests are typically required which involves multiple blood draws from the patient, many visits to the hospital, increased reagent volume and increased time to diagnosis. Biochip Array Technology allows for the simultaneous quantitative or qualitative detection of a wide range of analytes from one single sample. Therefore, it is faster, cost saving and more effective leading to better clinical decisions. Today the technology (BAT) is used in countless laboratories worldwide and a range of three biochip analysers are now offered.
The main basis of the Biochip Array Technology
- 9x9mm biochip which acts as a solid phase reaction vessel.
- Each of the biochips are pre-coated with an array of discrete test regions (DTRs)
- One biochip per sample used to generate multiple results.
- Randox Biochips hold up to 49 tests.
- Based on chemiluminescent signal emitting light, without heat which results a chemical reaction.
The key features and benefits of the Biochip Array Technology
Highly accurate testing
- The biochip array technology provides high standard of accurate test results with CV’s <10%
- Multiplex analysis minimises analytical variation between the tests.
Better diagnosis
- Increased patient information available through testing multiple markers
- Patients receive their results quicker compared to the traditional diagnosis.
Reduced sample volume
- Reduced sample required therefore patients feel more at ease.
Wide test menu
- Wide test menu provides a variety for clients and allows flexibility.
Multiple samples
- Multiple samples can be used on BAT which include the following; serum, plasma, whole blood, urine and many others which allows for flexibility in their testing
Cost consolidation
– The process reduces the amount of time spent on individual tests and associated laboratory costs

Assessing the risk of developing Alzheimer’s disease
World Alzheimer’s Month
World Alzheimer’s Month is a global campaign to raise awareness and highlight the challenge that surrounds the disease, hosted by the Alzheimer’s disease International (ADI) every September. During this month World Alzheimer’s Day also takes place, 21 September each year.
47 million people are living with Alzheimer’s worldwide, costing 604 billion USD per year. This number is expected to rise to 76 million people with the disease by 2030.1 The FDA have not approved a medication for the treatment of Alzheimer’s disease since 2003. More than 400 clinical trials are currently looking at new treatments for Alzheimer’s disease (AD) and many of them are actively recruiting. Many still regard the amyloid hypothesis as a key explanation for Alzheimers disease development and progression.2
Alzheimer’s risk
Alzheimer’s disease is not necessarily inherited as a single-gene mutation as the inheritance pattern is incredibly complex. Unlike familial Alzheimer’s disease, a multi-gene form usually affects those aged 65 and older. The gene with the greatest known effect on the risk of developing late-onset Alzheimer’s disease is called apolipoprotein E (APOE). It is found on chromosome 19 and the APOE protein plays a role in handling fats in the body, including cholesterol. 3
ApoE plays a key role in lipid metabolism and the scientific and medical community recognise it as one of the most powerful genetic risk factors for dementia and other neurodegenerative diseases. It has become one of the most widely studied gene variants in Alzheimer’s disease and constitutes a major consideration for preventive medicine.
ApoE exists in three common isoforms (ApoE2, ApoE3 and ApoE4) which are coded by three co-dominant alleles (e2, e3, e4). As such, six common ApoE phenotypes exist within the general population: E2/E2, E3/E3, E4/E4 (homozygous) and E2/E3, E2/E4, E3/E4 (heterozygous). Medical professionals recognise the presence of the ApoE4 isoform as a major genetic risk factor for development of Alzheimer’s disease. Therefore, the availability of analytical methods for rapid and reliable ApoE4 classification is advantageous.
Evidence Investigator
The Apolipoprotein E4 (ApoE4) Array is a research use only product developed for the Evidence Investigator. The ApoE4 Array measures both total ApoE protein levels and ApoE4 protein levels directly from plasma samples and using a ratio can classify patients as negative or positive for ApoE4. In turn we can then assess their risk for the development of Alzheimer’s disease.
2-plex Biochip Array
- Pan ApoE
- ApoE4
An individual’s ApoE status has been shown to affect pre-symptomatic risk, diagnosis, prognosis, and treatment response for a variety of diseases, in particular Alzheimer’s disease. The ApoE4 Array can rapidly and accurately detect an individual’s ApoE4 status directly from a plasma sample. In combination with medical and family history, medication and lifestyle, this can deliver valuable information for personalised medicine approaches.
The 2-plex diagnostic Alzheimer’s test has the utility to detect the likelihood of a person’s chance of developing the disease to assist in the research and development of a potential drug to combat or slow down the process of Alzheimer’s.

Randox Biochip Array (BAT) Technology free from Biotin-Streptavidin
Biotin, also known as vitamin B7, is involved with fatty acid metabolism, amino acid degradation, and gluconeogenesis. The recommended daily intake for biotin is roughly 30-70µg, which is extremely low, meaning that biotin deficiency is rare. Recently, there has been a surge in biotin supplementation mainly for beauty reasons, including: stronger nails and healthier skin and hair, resulting in the biotin craze on Instagram. Currently 162K posts are attributed to the biotin hashtag (#biotin) on Instagram. Whilst biotin supplementation is beneficial for numerous health conditions, including: multiple sclerosis (MS), diabetes, elevated cholesterol, and metabolic dysfunction, the increasing use of biotin by patients has created a problem with in vitro diagnostic testing.
With numerous manufacturers using biotin-streptavidin technology to develop in vitro diagnostic tests, combined with the rise in biotin supplementation use, the FDA (food and drug administration) issued an alert regarding the potential for erroneous results triggered by high levels of biotin in patient samples, at the end of 2017. Clinical decisions based on these false results from biotin technology can lead to inaccurate diagnosis and inappropriate treatment prescribed. The FDA confirmed that a patient, who was consuming high levels of biotin, died when a troponin tested was skewed and failed to show that the patient was having a heart attack. Other tests that can produce erroneous results include: cardiac, pregnancy, cancer and iron-deficiency tests.
(Halasey, 2018)
The image above highlights that in biotin-free patient samples, the analyte to be tested successfully binds to the biotinylated antibody and the labelled antibody ultimately ensuring accurate measurement. In the patient sample containing high levels of biotin, the biotin inhibits streptavidin’s ability to capture the analyte-antibody complex, generating falsely lowered results.
As 70% of all clinical decisions are based on results from in vitro diagnostic tests, it is vital that laboratories are selecting in vitro diagnostic tests that do not adopt the biotin-streptavidin technology to ensure accurate patient testing.
Randox do not utilise the biotin-streptavidin technology in the development of the Biochip Array Technology (BAT).
The Randox Biochip facilitates multiplex testing for faster, more comprehensive patient testing. This technology, free from biotin-streptavidin, uses capture antibodies bound to a solid substrate (biochip surface) as opposed to biotinylated antibodies used by other manufacturers. The Biochip also utilises enzyme labelled conjugate to enable chemiluminescent detection of the target in the patient sample.
Biochip test menu
The Biochip Array Technology (BAT) from Randox is capable of simultaneous multi-analyte diagnostic testing within the fields of clinical research and drugs of abuse testing. The technology works through combining a panel of related assays on a single biochip with a single set of reagents, controls and calibrators. An extensive range of Biochip panels are available, each optimised to provide the best performance.

Accurate and Robust
Like all the Evidence Series analysers, what sets it apart is technology. The Evidence Investigator is extremely well equipped to provide reliable results, while simultaneously robust enough to withstand frequent, heavy use.
Results are generated using a Charge Coupled Device (CCD) camera, which quantifies chemiluminescent light. This light measures the degree of binding between the patient sample and specific biochip bound ligands, generating highly accurate and reliable results.
Consolidation
The Evidence Investigator is the world’s first platform allowing consolidation of immunoassay and molecular diagnostics. This is achieved through utilising protein and DNA based biochips. By giving the user the ability to consolidate tests, the Evidence Investigator improves laboratory efficiency and reduces costs.
Advanced Reporting
The Evidence Investigator image processing software translates light signal generated from chemiluminescent reactions into analyte concentration. This removes the need for any manual processing of data.
Previously unreported tests can also be retrieved, so they can be tested retrospectively. This saves time, labour costs and reduces any reagents wastage. All data is then analysed on-board, removing issues related to human error and result manipulation.
