What is the coronavirus home test?
It is a finger-prick antibody test that will tell you whether you have been infected with the Sars-CoV2 virus which causes Covid-19. It detects the presence of antibodies in your blood that show your immune system has responded to the coronavirus. It cannot tell you if you currently have the virus; it is for people who have had symptoms and recovered, so that they will know they are no longer infectious and can return to work. People are usually immune to the virus once they have had it. There are case reports of some reinfections, but they are rare.
Is this the test in use at the moment?
No. That’s the standard PCR (polymerase chain reaction) test which is being used in hospitals to find out whether patients who are severely ill have Covid-19, so they can be treated appropriately. It tests for current infection and cannot tell you if you have had Covid-19 in the past. The government has said it wants to increase the numbers tested to 25,000 a day, but the last daily figure was just under 6,500. However, the pharmaceutical giant Roche has signed a deal to help, a testing centre has been opened in Milton Keynes, and the number of tests is supposed to rise to 10,000 within days and then 25,000. These will be mostly hospital patients as now, with further upscaling to 100,000 to reach key workers with symptoms.
