Healthcare staff to get coronavirus antibody tests from next week

Healthcare staff to get coronavirus antibody tests from next week”

Home use of the test - which uses a spot of blood from a finger prick rather than a full blood sample - has only been confirmed as accurate by an independent lab, and not yet by PHE.

While Ashton is glad that COVID-19 isn't spreading in her hospitals, the low number raises some concerns. Now, if you have symptoms, you can get tested regardless of your age or occupation.

On Wednesday, Superdrug became the latest business - and first High Street retailer - to offer the antibody test.

Hancock also used this evening's press conference to say that the government had agreed a deal for COVID-19 anti-body tests on the NHS.

Antibody testing, also known as serological testing, detects antibodies present in the blood when the body is responding to a specific infection, like COVID-19. It is a combination of both of these tests which will give United Kingdom businesses all the information they need to manage their whole employee population, to ensure that they do not put their colleagues or others at risk while the virus is circulating.

That's one of the problems Tim Brown, an infectious disease expert at the East-West Center, sees with using antibody tests in Hawaii.

Health Secretary Matt Hancock ordered 3.5million tests but it turned out the best of them could spot only 70 per cent of those who had been infected.

Both are likely to be used in the "test, track and trace" programme being launched next week, in which anyone who has been in contact with a coronavirus patient will be tested. An antigen is a structure within a virus that triggers the immune system's response to fight off the infection.

But the science behind the level of protection provided by antibodies is still in its early stages - the virus has not been around long enough to know what level of protection any antibodies give. For a while, doctors did not know whether patients who recovered from COVID-19 would develop antibodies against the virus.

Superdrug said it was "confident" in the accuracy and reliability of the test.

For this test, doctors take a blood sample from a patient to a lab where they assess whether antibodies in the patient's blood cells bind to or attack coronavirus cells.

These tests will begin to be rolled out from next week, with NHS staff being the first to receive them.

"Public Health England (PHE) as I say is evaluating them for the NHS so I would caution people against being tempted to have those tests".

What other COVID-19 tests exist?

"However, these tests have not been evaluated in the format that they are being used (finger prick at home and posting to a laboratory for reading) so we can not yet be confident in their sensitivity and specificity".

However, Abbott's statement said the test "has been validated for use with a venous blood sample that is taken by a healthcare provider". The antigen test could be useful because it may be able to detect the virus faster than current molecular tests do; taking minutes instead of days to produce test results.

This month, the Food and Drug Administration (FDA) issued an emergency use authorization to Quidel Corporation for its COVID-19 antigen test. The approval is so recent, the tests may not yet readily available at all testing sites in Philadelphia.
