How does Test to Release work?

@2xFill 1Created with Sketch.

Before the end of your trip: Check whether the country you are returning from is on the government travel corridor list. If your country is not on the list, order a Chronomics test to release kit. You will receive a unique reference number that can be entered into your passenger locator form.

Day one: Arrive in England from a quarantine country. Go straight to the place you plan to self-isolate. Start self-isolating according to the UK government’s instructions.

Day five: Your Chronomics kit will arrive in the post at your self-isolate address. Complete the kit and return it via a royal mail priority post box the same day.

Day seven to eight: Get your results. If negative, you are to end self-isolation.

I have already done a Chronomics COVID-19 test - can I use that?

No, only specific Test to Release tests purchased through this page may be used. You will receive a unique reference number that must be entered into your passenger locator form.

Can I use Test to Release in Scotland and Wales?

@2xFill 1Created with Sketch.

Test to Release only applies to England. Scotland, Ireland and Wales each have different rules.

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

@2xFill 1Created with Sketch.

With the Chronomics CE marked 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 four 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.
  • Failed - this result means it was not possible to accurately process your test in the laboratory. This is normally due to an incorrect saliva sample being provided (ie not providing enough spit, not mixing with the stabilizing fluid or eating/drinking before the test). We recommended taking another test as soon as possible.

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 CE marked?
