Antibody test coming

[dansus]

I paid £300 for a proper ELISA test, worth every penny.

My advice, get it done at a clinic by a professional.

There are many instances where the test can provide invaluable information.
Both my wife an i have had something. I say something because weve no way of knowing what it was for sure but my wife would be pretty vulnerable having a reduced lung capacity.
I worry getting it and passing to the wife and worry for thw wife getting it but if we knew we had it or the wife has had it and the symptoms weren't as bad as they could be then it would be a great weight off and give us both a better sense of normality.

I get you might want to know you've had it. But as that fact has no bearing on your chances of getting it again, even if you require a higher bio load, what use it it? we have still seen on signs of any form of resistance, despite 100,000 of thousands having caught and recovered, from the virus.
Boris's " Game Changer" is an expensive, functionally useless, drain of finite public and private resources. That achieves nothing of use. But may offer false peace of mind to some who are fooled.

if someone could flag up, just, one case where someone has shown resistance, never mind immunity. I'd be playing a different tune.

May or may not be true but I'm not aware of a single case of repeat infections.

The salient point here is we have no evidence of either immunity or resistance. With the numbers infected, that should be well established. It is in all other outbreaks, of this size. As we have only just got an antibody test. We currently have no idea how many have been infected. Well, unless they've been hospitalised and tested. So as a diagnostic and statistical hospital test, this could well be welcome. But it still has no bearing on if you will be re-infected, or not. Which is the whole idea of an antibody test.

Reinfection is highly likely without intervention, question is when. Tracking with regular testing will give us an idea of how long we have useful antibodies. China is into month 4 of tracking, so its at least 90 days.

After you have been confirmed with an Abbott or ELISA test, you can use a lateral flow test at home, which cost about a £5 atmo, but will get cheaper.

Some evidence of growing immunity is emerging in UK, with infection rate declining for regions with more cases.

Your link is looking at various scenarios, depending on different levels of resistance and immunity.
Perhaps I missed the scenario where they assume zero resistance or immunity.

The scenarios they look at are
(A) A short duration (1/σ3 = 40 weeks) of SARS-CoV-2 immunity could yield annual SARS-CoV-2 outbreaks.
(B) Longer-term SARS-CoV-2 immunity (1/σ3 = 104 weeks) could yield biennial outbreaks, possibly with smaller outbreaks in the intervening years.
(C)Higher seasonal variation in transmission (f = 0.4) would reduce the peak size of the invasion wave, but could lead to more severe wintertime outbreaks thereafter [compare with (B)].
(D) Long-term immunity (1/σ3 = infinity) to SARS-CoV-2 could lead to elimination of the virus.
(E) However, a resurgence of SARS-CoV-2 could occur as late as 2024 after a period of apparent elimination if the duration of immunity is intermediate (1/σ3 = 104 weeks) and if HCoVs OC43/HKU1 impart intermediate cross immunity against SARS-CoV-2 (χ3X = 0.3). (A) χ3X = 0.3, χX3 = 0, 1/σ3 = 40 weeks, f = 0.

As far as I can see they assume at least 40 weeks protection against reinfection in the worst case scenario.

You might find this interesting

The so-called “re-positive” cases have raised fears that an infection with the new coronavirus, SARS-CoV-2, could “reactivate” in recovered patients or that recovering from the infection may fail to produce even short-lived immunity, allowing patients to immediately become re-infected if they are exposed.

The new data from Korea should ease those concerns.

Quite a good explanation of the latest Korean data here, if you’ve the time to watch it. It’s tentatively positive.

Antibody tests will be available on the NHS, government says https://a.msn.com/r/2/BB14pBcc?m=en-gb&referrerID=InAppShare

Antibody tests will be available on the NHS following an agreement between the government and pharmaceutical firm Roche, Downing Street has said.
Health Secretary Matt Hancock will set out further details later about a deal on the supply of the tests, which follows negotiations.
The prime minister's official spokesman told reporters: "The tests will be free for people who need them, as you would expect.
"NHS and care workers will be prioritised for the tests."
