The agency also said that antibody tests shouldn't be used to make important decisions about re-opening.
The Food and Drug Administration has also said that antibody tests are not reliable.

The CDC has released new guidance on antibody tests, warning that they can be wrong half the time and shouldn't be used to inform important policy decisions.
The antibody test, also known as a serologic test, is a blood test that checks the body to see if it has antibodies that can fight COVID-19, and can help people figure out if they had COVID-19 and recovered.
The immune system creates antibodies to fight disease, and often these antibodies remain in the body after recovery, and can be donated to people currently fighting coronavirus.
But this medical test is often inaccurate. Sometimes the test can result in a false positive, wrongly suggesting a patient does have coronavirus-fighting antibodies, or a false negative.
"Serologic test results should not be used to make decisions about grouping persons residing in or being admitted to congregate settings, such as schools, dormitories, or correctional facilities," it says on the CDC website. "Serologic test results should not be used to make decisions about returning persons to the workplace."

CDC = Crappy Decisions Continuously.
[[So why bother reopening the country, getting our civil rights back, etc? Everybody around you is a walking lethal threat no matter what.]]
they are conditioning low info people to believe this- that is why you saw staten islanders screaming at a woman in a store not wearing a mask- the government has conditioned these low info peeps to believe that everyone not wearing a mask is a lethal walking biohazard leaving piles of bodies behind them as they walk through life without a mask
you see it everywhere now- people are scared to death that someone without a mask will cause them to become infected and die- you see people glancing at unmasked folks, shaking their heads in disgust- and we’re just a step away as a nation from people ratting on people not wearing masks- The ones doing the reporting believing they are doing humanity a ser4vice-
It’s not hard to see how the Nazis brainwashed everyone to rat on others- on friends, family even- We thought ‘oh that could never happen here in the US- we know better than the Germans did- we’d never allow that to happen here’- yet here we are- folks ratting on others for simply not weariness a mask in outdoor places even- You even have governors setting up hotlines for people to rat on others-
How quickly people become complaint to a dictatorship like the left when the opportunities present themselves to do- there are just so many people unfortunately that would- and are infact, trading away their rights just to be complaint with government rule-
“Ve haf ways of.... determining your infection level.... UND you vill beleef US!, or Else! pfft!”.
The real anti-social socialists of medicine. Their name says it all ......CD.... CONTROL. Oh yeah? how do you “control” a disease without viable testing. So... you control us rather, with your “scientific” greta thunberg retard “face” of “science”... by consensus. Which science, real science has never been a consensus-— it can not be, and be supportable.
Everybody stay fearful until Trump is out of office... and not even then.
And of course their Wuhan virus test is perfect
Of course these antibody tests shouldn’t be relied on, when these numbers are added to the mixture, it lowers the death rate percentage to that of the flu...LESS THAN 1%
Liberals — “TESTING, TESTING, TESTING....WE NEED MORE TESTING!!!! Trump failed because he didn’t test.”
CDS — “testing is useless.”
Testing is SO USELESS my God these people are just idiots you get the test and 20 minutes later you can become infected WTH are these idiots even talking about!!
yes, some antibody tests aren’t very accurate for a number of reasons and the buyer should certainly be aware.
but actually, we have blood antibody tests for many infectious diseases (covid19 appears to be one of these at, least for some tests on the market) that are very good and can be relied on as useful data for epidemic decision making purposes. especially if confirmatory tests exist for the same person.
it depends on the skill and experience of the reference lab handling the validation of the test, the training of the med tech getting the sample, the skills and experience of the lab people running the test, and the quality of the private vendor’s design and development of the kits and machine for the highest possible accuracy (sensitivity and specificity).
after that, of course, the quality and honesty of the statistical study using even an accurate test becomes the most important factor for application to health policy. unfortunately, that part of it is usually in the hands of so called “experts.”
I predicted this was going to be the new mantra as soon as I read about the antibody study in Santa Clara and LA counties over a month ago. It showed the number of infected to be very high and that didn’t fit the narrative of the left, so antibody testing has been SQUASHED!
Yawn.
Tomorrow, it will be recommended as “better than nothing”.
The problem with the SARS-CoV-2 antibody tests is they were developed and released with close to no oversight whatsoever. It was an overreaction to their failure on the initial COVID-19 tests, where they didn’t let anyone build working test kits and the CDC test kits were delayed and broken. So when it came time to develop antibody testing, the CDC basically told everyone to do whatever they wanted and so everyone and their brother threw together a “test”.
There’s something like 60 different antibody tests out there. The worst of those is wrong up to half the time. Most aren’t that bad, but without any oversight or independent testing, it’s a complete mess trying to figure out how good a particular test is.
This is a story about the CDC bungling two different kinds of tests in two different ways. It has nothing to do with any inherent problem with antibody testing.
Why is CDC seemingly generalizing that all manufactures are making junk antibody tests when at least one manufacture has distinguished itself for its accurate tests?
Demand Surges For Abbott Labs Rapid Coronavirus Test As New Data Support Accuracy
Send "Orange Man Bad" federal and state government Democrats and RINOs home in November!
Supporting PDJT with new patriot federal and state government leaders that will promise to fully support his already excellent work for MAGA and stopping SARS-CoV-2 will effectively give fast-working Trump a "third term" in office imo.
I don’t think that’s an antibody test.
You’ve got it wrong. The Santa Clara County, Los Angeles County, and Major League Baseball (front and back office, not athlete) testing shows the prevalence of the disease to be VERY low in the population. As I recall, it was under 1% in MLB and less than 3% for LA and Santa Clara.
“The CDC is often wrong!”
The test itself is more accurate than the CDC.
The CDC is useless and should be shut down! Their one job was to prepare for a pandemic and we all know how that turned out.
the only right answers are the ones that require more lockdowns
btw...why are we not hearing about how the summer heat will help? like seriously, no one is saying that.
is that yet another reason why this virus is different from all others we know of?
Is there any data to support this conclusion? What is the false negative and false positive rate?
