SARS-CoV-2 (COVID-19) Testing Service

UKAS accredited service laboratory for processing COVID-19 tests

Viral RNA extraction, qRT-PCR and rapid whole genome sequencing workflows for detection of all known variants of SARS-CoV-2

A complete SARS-CoV-2  testing workflow from RNA extraction through to qRT-PCR and rapid viral whole genome sequencing (WGS) to support testing laboratories. 

Our high throughput service facility can perform up to 10,000 qRT-PCR COVID-19 tests per day ensuring test results are delivered quickly and efficiently.

If you are looking for a high throughput UK laboratory to process your SARS-CoV-2 (COVID-19) tests, we can help.

Service Capabilities:

Viral RNA extraction service

Our viral RNA extraction service isolates viral RNA from nasopharyngeal swabs or other biofluids. We use a magnetic bead-based technology which is ideally suited to high through-put processing and enables us to carry out extractions at scale. The purification of high-quality RNA free from protein and other impurities is required for downstream qRT-PCR or rapid viral whole genome sequencing (WGS).

SARS-CoV-2 multiplex qRT-PCR service.

Our SARS-CoV-2 qRT-PCR service uses the Nonacus VirPath SARS-CoV-2 Multiplex qRT-PCR Kit. This kit is CE-IVD marked and is one of the few COVID-19 qRT-PCR tests to pass the stringent accuracy and sensitivity requirements set for Fit to Fly, Test to Release and general COVID-19 testing.

  • Detects all known variants
  • CE-IVD marked
  • Approved for Test to Release

SARS-CoV-2 whole genome sequencing

From 15 February 2021, all international arrivals in quarantine are required to take a test on or before day 2 of their quarantine period for variant surveillance. This will require whole genome sequencing of the SARS-CoV-2 genome in addition to the current qRT-PCR test.

We have over 6 years of experience in developing and manufacturing sequencing products and delivering sequencing services for diagnostic testing. In May 2020 we were funded by the UK Government (Innovate UK) to develop a novel rapid method for whole genome sequencing for viral surveillance which means we are well placed to offer customers this as a service.




SARS-CoV-2 WGS service

Our WGS service uses a robust and rapid method for whole genome sequencing of the SARS-CoV-2 virus that is ideally suited for the Test to Release programme and will deliver data that meet the required standards:

  • All samples with cycle threshold (CT) values of <30 (defined as equivalent to ~10,000-1,000 viral genome copies/ml) will be sequenced.
  • Coverage guarantees:
    • All SARS-CoV-2 genomes will have a minimum sequencing coverage of 50% at >= 30x coverage.
    • For samples with a CT <20, (defined as viral genome copy number equivalent of <1,000,000 viral genome copies per ml,) 95% of samples should have a reference genome coverage breadth of >97% at >=30x coverage.
    • For CT above 20, defined as viral genome copy number equivalent of >1,000 per ml, 95% of samples should have a reference genome coverage breadth of >75% at >=30x coverage.
