Next Generation Sequencing (NGS)






Next Generation Sequencing

Next-generation sequencing (NGS) is a sequencing technology that offers speed, scalability and ultra-high throughput. The technology can be used to determine the order of nucleotides in entire genomes or targeted regions of DNA or RNA. NGS has applications in environmental, agricultural and forensic science as well as genomic and clinical research.

NGS Capabilities

Whole Exome Sequencing (WES) is a wildly used NGS method that involves sequencing every protein coding region (approximately 21,000 genes) to identify any variants that may increase the risk of developing certain conditions or impact health/lifestyle. WES can be used across a broad range of applications including genetic disease, population genetics and cancer studies.


  • Attains widespread coverage of coding regions
  • Cost effective alternative to Whole-Genome Sequencing (WGS)
  • Smaller data set provides faster and easy data analysis compared to WGS approaches

Human Whole Genome Sequencing (hWGS) involves sequencing very single base in your DNA (approximately 3.2 billion) to identify any variants that may increase the risk of developing certain conditions or impact health/lifestyle. This sequencing method has many applications including identifying genetic disorders, mutations responsible for cancer progression, as well as monitoring disease outbreaks.



  • High-resolution view of the genome
  • Detection of all variant types
  • Low cost, fast library preparation

16s rRNA gene sequencing involves the analysis of the prokaryotic 16s ribosomal RNA gene which is found in all bacteria and archaea. This sequencing approach is extremely useful for microbiome research studies. 16s rRNA gene sequencing has a number of applications including, environmental, clinical and food



  • Identification and taxonomic classification of bacterial species
  • Fast speed and cost efficient
  • Discovery of novel pathogens


Shotgun sequencing reads all the genomic DNA in the sample, rather than just one specific region. This sequencing method provides a vast amount of genetic information as it can identify archaea, bacteria, fungi and viruses.


  • Less labour intensive than other sequencing methods.
  • Faster process than clone-clone sequencing
  • Requires less DNA



qPCR allows for the analysis of particular variants of specific locations. It is a good choice when interrogating  a small region of DNA on a limited number of samples. Real-time PCR can be used for both qualitative and quantitative analysis.

Advantages and Applications of qPCR 

  • Reactions are run, and data is evaluated in a unified, closed-tube qPCR system.
  • qPCR assays can be used to precisely monitor changes in gene expression.
  • Highly sensitive and reliable variant detection .
  • Quick and Simple Workflow
  • Primary equipment already available in most labs.

Genotyping Services



Genotyping Services

The Randox Genomics Services Department currently has target genotyping solutions in multiple areas. Genotyping is the process of analysing DNA to detect SNPs of interest. These SNPs are compared to reference SNPs, available from years of genetic research, to determine differences in genetic makeup.

Genotyping Advantages and Applications

Clinical Diagnostics

  • Can help determine whether specific resistance genes or genetic mutations in bacterial strains- make it insusceptible to one or more antibiotic drug.
  • Can be used to help monitor variants during pandemics, identifying when new variants become more predominant.

Clinical Research

  • Allows researchers to focus on genes, variants, and genomic regions of interest relevant to certain disease or traits of interest.
  • Enables the study of populations not supported by standard products and can be used to create personalised drugs.

Food & Agriculture

  • Identifies potential genes for improving breeding and management programs.
  • Can be used to increase yield and improve quality


Pharmacogenomics (PGx) is the study of how a person’s DNA effects their drug response. This is a relatively new field in science but it is expected to be the future of medicine as it focuses on personalised medicine and treating every patient individually.

Microarray Technology for PGx

At Randox we use Illumina’s Infinium Global Diversity Array with Enhanced PGx microarray to test for pharmacogenomic markers. This is the most comprehensive genotyping microarray on the market for pharmacogenomic research. The microarray features over 44,000 genome-wide PGx markers which span more than 20000 pharmacogenomic targets and gives 100% coverage of priority level A and B CPIC genes.

Genotyping Panels

  • null
    GSA + Custom content

    Over 710,000 SNPs across the human genome with additional DTC content.

  • null
    GDA + Enhanced PGx

    Over 1.8 million SNPs across the human genome enhanced with pharmacogenomic specific markers.

OLINK® | Comprehensive Biomarker Discovery


Let Experts at Randox Run Your Samples

As one of the UK’s first commercial partners of Olink® Proximity Extension Assay (PEA) technology, Randox offer scientists involved in drug development, clinical, or basic life science research, the service they need to run large-scale discovery proteomics.


Randox offer customers access to the entire Olink® protein library of ~3000 protein assays for exploratory proteomics and multiomics.

Olink® Technology- How it Works

Olink Proximity Extension Assay (PEA) technology offers a new method for measuring & detecting proteins of interest in a wide variety of sample types.

Using real-time PCR amplification, Olink platforms such as the Explore 3072 uses dual recognition with antibody- protein pairs in high multiplex to create 96 unique DNA reporter sequences. Using this approach, researchers can incorporate Olink’s kits into their workflow to measure and detect low abundance proteins whilst ensuring exceptional specificity and accuracy in serum or plasma samples.

The platform uses PEA technology combined with Next Generation Sequencing (NGS) readout methods to measure the relative concentration of proteins in liquid samples.


Olink®- Driving the Future of Healthcare

Driven by precision medicine, the future of healthcare relies on a new generation of therapies to deliver the right treatment to the right patients at the right time. Proteomics is set to be at the forefront of this movement.

Technological limitations previously restricted comprehensive investigations of proteomics. Inhibiting large scale studies examining broad ranges of proteins in large numbers of human samples.

Olink® PEA technology provides an example as to how technological developments have eradicated past issues involving:

Offering efficiency without compromising on accuracy, the Evidence Investigator is the perfect fit for medium throughput laboratories seeking maximum use of bench space.

Molecular Testing

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.

Pathogen Detection

STI and Respiratory Arrays

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

These unique biochip assays permit high discrimination between multiple targets in a number of 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

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.
