The Chronomics saliva test detects the presence of the virus that causes Covid-19, known as SARS-CoV-2, using an RT-PCR method. This is the current gold standard for testing – our labs use the same scientific method as the equally accurate (but more invasive and uncomfortable) swab tests.
You’ll receive one of four possible results from your test:
Positive – this means that the sample you provided contains SARS-CoV-2 viral RNA. You can get this result even if you don’t have symptoms. You should isolate in line with current government guidelines and seek help and advice if you become unwell.
Negative – this means that the sample you provided doesn’t contain detectable levels of SARS-CoV-2 viral RNA. However, you could have been previously infected by the virus and you could also be infected in the future.
Inconclusive – fewer than 1% of tests come back ‘inconclusive’, so it’s very unlikely this will happen. If it does, it means your sample didn’t meet the requirements to be reported as a Positive result, but there was a partial signal that the SARS-CoV-2 virus could be present in your system. Normally we’ll re-test your sample if we can and we’ll email to let you know.
Failed – again, this result is produced by only a very small percentage of tests we run. It means we haven’t been able to accurately process your sample in our lab. Usually this will be because there’s not enough saliva in the tube, your spit hasn’t been mixed with the stabilizing fluid, or you’ve had something to eat or drink too close to providing your sample. Failed tests are very rare but, if you do get this result, we’ll tell you why this has happened if we can. If you’d like another test, or you’d like to speak to one of our team, please email us on firstname.lastname@example.org and we’ll be happy to help you out.
