Molecular Testing on the Evidence Investigator

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.

Pathogen Detection

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.

Mutation Detection

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).

SNP Genotyping

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.
