Rapid & Reliable Genetic Assessment
Genetic Assessment of Patients with Suspected Familial Hypercholesterolemia (FH)
- Early diagnosis of specific mutations reducing morbidity and mortality from premature CVD ensuring better outcomes & therapeutic intervention
- Saving time & costs by reducing the number of traditional clinical & genetic tests
- Combination of multiplex PCR and Biochip to distinguish between multiple wildtype and mutant DNA regions
- Cascade screening can be performed across both FH arrays to further improve diagnosis
- Provides information on the phenotype and prognosis which cannot be identified through traditional lipid level testing
- Suitable for use on the Evidence Investigator, a semi-automated analyser identifying FH in under 3 hours
The Familial Hypercholesterolemia (FH) Arrays I & II are rapid, simple and accurate diagnostic tests which enable simultaneous detection of 40 FH-causing mutations (20 mutations per array) within the low-density lipoprotein receptor (LDLR), apo‑lipoprotein B (ApoB) and proprotein convertase subtilisin/kexin type 9 (PCSK9) genes. Generally, mutations within the LDLR gene are the most common, with a prevalence of 1 in 500. The ApoB gene has a prevalence of 1 in 1000 and the PCSK9 gene less than 1 in 2500.
FH patients have elevated levels of total cholesterol (TC) and LDL-C from birth and, if untreated, develop coronary heart disease (CHD). FH is characterised by twice normal LDL-C levels in early childhood, and early myocardial infarction. A strong positive family history can imply as much as a 12-fold increased risk of early coronary disease.

Randox Alzheimer’s Array on the Evidence Investigator
Alzheimer’s disease
Alzheimer’s disease is the most common cause of dementia. It is defined as an irreversible, progressive brain disorder, in which parts of the brain are damaged over time. As this happens symptoms develop, but also get worse.
Dr. Alois Alzheimer discovered that in Alzheimer’s disease the connections between the cells and brain tissue are lost because proteins build up and form abnormal structures called “plaques” and “tangles”. 1 A healthy brain contains important chemicals which send signals between the cells, however, those who suffer with Alzheimer’s have less “chemical messengers.” Therefore, the signals don’t get passed on. 1
Risk factors
Age is the biggest risk factor. Alzheimer’s disease is more common amongst older adults. In the UK there are over 40,000 people under the age of 65 who suffer with some form of dementia. 2 Studies also state that women over the age of 65 are twice as likely to develop Alzheimer’s disease than men – although there is no clear evidence as to why.
There are two different types of Alzheimer’s. The early on-set variant of the condition is very uncommon but strikes people younger than 65. Often people with early-onset Alzheimer’s develop symptoms in their 40s or 50s. Whereas, late-onset Alzheimers is more common and affects people age 65 and older. 2
Symptoms
The disease slowly destroys memory and thinking skills. The earliest symptoms are memory lapses where they may struggle to remember recent events or learn new information, or even forget important items for day-to-day life for example, their keys, glasses or mobile phone. Memory loss due to the disease can increasingly interfere with their life as often the ability to carry out simple tasks can become a struggle. As a result, the person suffering can become anxious, irritable and can even be depressed.
In the later stages of Alzheimer’s, the symptoms become more severe. The individual will become less aware of what’s happening around them. They may have difficulties eating, walking and will require additional help and support with their daily activities from their loved ones or from a carer.
Unfortunately, there is no cure for Alzheimer’s Disease, although, there is treatment that can help manage the symptoms.
The Randox Apolipoprotein E4 Array
Randox offers The Apolipoprotein E4 (ApoE4) Array.
The Apolipoprotein E4 (ApoE4) Array is a research use-only product developed for the Evidence Investigator, which is a semi-automated benchtop immunoassay analyser which can process up to 2376 test per hour as well as up to 44 analytes screened per biochip.
The ApoE4 Array measures both total ApoE protein levels and ApoE4 protein levels directly from plasma samples and by using a ratio it can classify patients as negative or positive for ApoE4. In turn we can then assess their risk for the development of Alzheimer’s disease.

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.
Evidence
The evidence analyser is the world’s first protein Biochip Array Technology system and has truly transformed laboratory diagnostics worldwide. As the first of its kind, the Evidence has introduced higher standards of quality efficiency and reliability to numerous sectors including hospitals and clinical laboratories, forensic and clinical toxicology, pharmaceutical/CRO applications, as well as veterinary laboratories.
Evidence Evolution
The world’s first fully automated random access Biochip testing platform. The Evidence Evolution is set to revolutionise current diagnostic testing.

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.
