Actual accurate antibody results

[Givenupno]

As far as I am aware these are the first meaningful antibody test results to be published.

I live here, and we have been COVID free for about 55 days I think. Over the last couple of weeks they have been antibody testing and the first preliminary results are in the attached link.

Interestingly on 74% of those who tested positive have antibodies

14% of those who had been in close contact with positive cases also have antibodies despite not having knowingly had it.

that is interesting. ONly 74% of pcr positive cases were antibody psitive. I have a strong suspicion that the T cell mediated response is what is important as has been sugessted rather than relying totally in antibodies.

I read it seems to fade in weeks.

Oh, also more under 40s were negative for antibodies that over 40s, despite having had the virus. Maybe a different response with age. And BAME more likely to have antibodies, too...

• And BAME more likely to have antibodies, too...”

Purely stating a fact, but the BAME population over here compared to most of the UK will likely be quiet low.

Given all the guessing and hysteria that’s normally on here I am a bit surprised That some actual real world data on who does and doesn’t have the antibody hasn’t generated more discussion.

The guess based on the figures available so far is that over 2000 of a population of 85,000 have had the virus. That’s with no positive cases for nearly two months so would imagine the figures in UK are far higher

I think that maybe it is because there seem so much uncertainty around this area, and still much is being found out. It seems it might only last for a few weeks, vary with age, race, and how severe the case was, along with the T cell response, and on top of this there are things like false negatives and accuracy of the tests and if immunity comes from having antibodies...so complex

Interesting. So about 2.35% as compared to the estimated general UK prevalence of 6.7 according to the ONS (higher in London)

But if under 40s tend to not test positive for antibodies after the virus surely it depends on who they test? and the real rates may be higher.
