The rate of Covid-19 (coronavirus) infection in the UK continues to increase rapidly every day. Better2Know are now offering two different testing methods for Covid-19. While both tests are accurate and useful, it is important that you choose the test which is right for you. Here, we explain the differences between our Covid-19 tests.

If you have decided that you want to get tested for Covid-19 but are not sure which test to choose, then you’re in the right place.

Below is a summary of the differences between our two Covid-19 / coronavirus tests:

  PCR Swab Test Instant Blood Test
How does this test work? Extracts, amplifies and identifies the viral RNA sequence of the virus Looks for IgG / IgM antibodies produced in response to the virus
What sample is required? A combined throat/nose swab A finger prick blood sample
When can this test detect Covid-19? 5+ days post-exposure 7-14 days post-symptoms
When will I receive my results? Within two days of your sample’s arrival at the laboratory Within 10 minutes at your appointment
Can I do this test at home? Yes, with our Home Sample Collection Kit No, this must be performed in a clinic

Do you currently have Covid-19 symptoms?

Symptoms of Covid-19 include a fever and a new, continuous dry cough. If you are currently experiencing symptoms and you are worried that you may have Covid-19 now, we advise that you choose our PCR Swab Test.

Have you felt unwell within the last couple of months and want to know if this may have been due to Covid-19?

If you have recently recovered from a mild or moderate illness and you are curious to understand whether this was Covid-19, our Instant Blood Test is the right test for you. This test will tell you whether you have had Covid-19.
