More information

Is this an at-home test or is the analysis done in the lab?

With the Chronomics saliva test, the collection of the sample can be done anywhere - at home, work or in the clinic. Other tests (such as nasopharyngeal swabs) normally require a trained medical professional to administer correctly and are more invasive and painful.

What does this test show?

@2xFill 1Created with Sketch.

This test detects the presence of the virus that causes COVID-19, known as SARS-CoV-2, using an RT-PCR method. There are three possible outcomes from the testing:

  • Positive - testing positive for the virus means that the sample provided contains SARS-CoV-2 viral RNA. This result could be returned even in the absence of symptoms.
  • Negative - this result means that the sample provided does not contain detectable levels of SARS-CoV-2 viral RNA. However, you could have been previously infected by the virus and you could be infected at a future date.
  • Inconclusive - this result means that the test results did not meet the requirements to be reported as a positive detection of SARS-CoV-2 viral RNA in the sample, and should be treated clinically as Not Detected. However, this also means that there was partial detection of a signal from SARS-CoV-2 that warrants notification under duty of care for further investigation. Re-testing in these cases is recommended.

If the test is so great, why isn’t the NHS using it already?

Our test is currently pending approval for use in the NHS. Meanwhile we want to offer our spare lab capacity to help others. Read more in our blog post "Chronomics’ solution to scale mass testing for COVID-19".

Why is Chronomics now doing COVID-19 testing? Aren’t you an epigenetic testing company?

@2xFill 1Created with Sketch.

Our day job is analysing epigenetic data from saliva samples to give actionable health insights. However, we’re currently diverting part of our saliva testing resources to help in the fight against the COVID-19 pandemic.

Are you FDA approved?

We are currently in the process of receiving FDA Emergency Use Authorization (EUA). Read more in our blog post, "PCR vs antibody, FDA approved, CE marked? The landscape of COVID-19 testing explained".

Where can I find the instructions for use and performance data about the test?
