The government test coordinator has urged the public to wait for an approved home antibody test kit instead of buying one from the Internet.
Professor John Newton told the Commons Science and Technology Committee that the public must await an approved home test that is currently under evaluation.
The government announced on Thursday that more than 10 million antibody kits were being purchased for use in hospitals and nursing homes.
It comes after high street chains, including Superdrug, started offering a home antibody test package for £ 69.
When asked about the new home tests, Prof Newton said that better tests would soon be available to the public.
He said, “The public should be aware that those tests are not the same as those we have reviewed and approved for use.
“The laboratory tests have a much higher accuracy standard.
“We do not currently recommend that people rely on the tests that will become widely available.
“My advice would be to wait until we have better tests that will be available in a similar form very soon, although they are currently under evaluation.”
His comments echo those of NHS Medical Director Professor Stephen Powis, who said earlier this week that people should be careful about buying house kits.
