What Antibody Studies Can Tell You — and More Importantly, What They Can’t
ProPublica ^ | April 28, 2020 | Caroline chen

Posted on 04/29/2020 1:54:34 PM PDT by luv2ski

In the past two weeks, researchers across America have begun announcing results from studies showing that there have been many more coronavirus infections in their communities than were previously recorded.

Findings have come in from Santa Clara County, California, as well as Los Angeles, New York, Chelsea, Massachusetts, and Miami-Dade County, Florida. The debates began immediately. What did the study results actually mean? If more people were infected than previously known, did that mean the death rate is actually lower than previously thought? Is the coronavirus actually more like the flu, after all? And are we close to “herd immunity,” meaning enough people are infected that the virus won’t spread easily anymore?

These studies all were based on antibody tests, which are diagnostics that can look in a person’s blood and see if there is evidence of prior infection. In the past month, as these tests have reached the market, researchers have launched large-scale studies, known as sero-surveys (sero is short for serology, the study of blood serum). By running these surveys, scientists are finally able to start estimating how many people have been infected, which can give us information about how deadly the disease is and where the disease was most concentrated geographically.

Of course Fauci has already put the kabosh on the anti-bodies saying doesn’t really mean you’re protected.

Fauci has an agenda, and it isn’t a pro-USA one...

Fauxi has been more wrong than right. He and the Scarf sold the President a Doomsday scenario that hasn’t panned out. Is this a particularly nasty bug? Yes. But it’s not worse than the Asian Flu or Hong Kong flu, and far less deadly than the Spanish flu. None of them caused the country to shut down.

And you cannot physically stop the spread of the virus. It will reap its grim toll. The only question is whether we will accept the inevitable risks attendant with the path to herd immunity and save what’s left of our country, or continue the futile attempt to avoid those risks while destroying what’s left of the country.

Fauci is just front running what will be the next scam....anti body testing, anti body testing, anti body testing. Trump why are we not doing more, why have we lagged from the gallery....then comes the well, they don’t tell us anything, do they so we will then be back to ventilators.

The best thing they can do with Fauci and the whitehouse loonia is to send them down to hold targets for the white house executive service qualifications.

Agreed. A very good and informative read.

“The problem is there are people who will think, ‘Oh, yeah, I had this nasty flu, or cough, or whatever, and I think I had it.’ And if you said to them, ‘Would you like to get tested?’ They would say, ‘Abso-frickin-lutely!’” said Marm Kilpatrick, a professor at the University of California at Santa Cruz who studies infectious diseases. Conversely, people who felt totally healthy could be less inclined to participate.

And count me in group #1. Had my test done today. lol.

Everything in this article was great....until the last sentence:

“how to fight the disease at local and state levels, as a country and as a global community.”

“Global Community”. An insight into the authors mindset and training?

It seems to me all this analysis still hasn’t caught up with the Diamond Princess. (But at least this article doesn’t ignore it.)

How far back would this test be valid? I think I may have had the Chinese flu starting Dec. 11. Is it too late now for an antibody test?

So there’s no point in finding a vaccine

Mindset doesn't make this global. The virus makes it global.

Well, he’s right in at least two ways, though one is simply not proven yet.

1) we don’t yet know the immunological characteristics of the disease it’s just too soon.

2) a sizeable number of those positive tests could be folks that are currently infected including those not even sick yet, since the serum tests detect antibodies starting about 4 days from exposure in about 70% of cases.

If this virus has a “sleeper cell” quality, there could be the possibility it would not show antigens until activated.
