Antibody tests used to determine if people have been infected in the past with Covid-19 might be wrong up to half the time, the US Centers for Disease Control and Prevention says in new guidance

Antibody tests, often called serologic tests, look for evidence of an immune response to infection."Antibodies in some persons can be detected within the first week of illness onset," the CDC says.They are not accurate enough to use to make important policy decisions, the CDC said.

Therefore, its best to use tests with high specificity -- which are unlikely to throw up a lot of false positives -- and in populations where doctors suspect there are many cases," the CDC said.The Food and Drug Administration has also cautioned about the accuracy of antibody tests.

That’s an expensive mistake

'Might' be wrong half the time? What a broad open-ended statement CDCgov

First they screw up the initial test which caused a major delay in testing. Now they screw up the antibody tests. At this point, a coinflip is more reliable than the CDC.

webbdiagnostic has a Antibody test kit, Revealcovid-19, that is 99% accurate. Developed in North America, made in the USA. FDA reviewing for approval. European CE mark approval came last week. drsanjaygupta CP24 CBCToronto cnnhealth TIMEHealth CuomoPrimeTime POTUS

Well that sucks. Do people who pay for test get money back?

We should refer to the orange dummy to find out what else is he going to pull out of his ass now.

Seriously ? Aren’t there like a million or more scientist in this world. And billions $ available. And we can’t get a simple test right. Ma come on. Wth. A simple blood test. It’s been months. China had this crap since sept or oct. No one can figure this out ? Where Gates Lol

The dead don't have a choice only the living If you're serious about your well-being, there's a remedy for the sick ones God Healing Oil, A Healing balm for coronavirus and other deadly diseases Truth is rare, believe it when you see it Kindly Dm if you are ready for the cure

This title is extremely misleading

Do people actually still trust the CDC or CNN? After all the lies they spewed about COVID before thousands of people started dying?

Statisticians, mathematicians and bioinformaticians have been saying this since the beginning of the outbreak. The most reliable metric is unfortunately how many people are in hospital beds.

Antibody tests wrong half the time, a vaccine likely at least a year away, the possibility that Bad Orange Man win again in November, etc. I likely will never leave my house again. Simply too risky.

Well cnn is reporting this so there may in fact be no story at all to begin with 😂

trussia is working this pandemic to the max.

poll Keep your test?

But, have you seen my hair? It needs to be cut!

The weather forecast is wrong HALF THE TIME, but nobody makes a big deal out of it.

The United States can't do anything right with this administration in control. Tests that are wrong half the time are no tests at all.

Yep

America virus has been to killing thousands of people

Like CNN ... wrong half the time.

“Might be..” “Up to..” Gotta love that vague language.

All you have left. Tests are the way, until they startvmaking you look bad.

Problematic virus test kits and antibody test kits.

They are doing 'spit tests' in prisons. WRONG ALL THE TIME.

Save time and money. Just flip a coin.

The FDA loosened its approval standards in order to get more antibody tests out on the market quickly. The agency started to allow companies to sell tests 👉 without first providing evidence that they worked.

Wrong up to half the time describes CNN perfectly.

iPowerPlace It's about time you caught up with the rest of the world.

How inept is the medical community. No one knows anything. No one can agree on anything. Drs day this then drs say that. Apparently even testing for it is a 50/50 gamble at nothing. We’re screwed no matter what. Doomed.

Don’t tell PattyMurray she is convinced testing would have saved everyone’s lives.

CDC also says that covid doesn’t survive on surfaces for long. Can we please stop stock piling wipes so I can just to a basic cleaning of my house?

Might be wrong, indeed.

Sounds like CNN ... wrong half the time.

💜❤💜❤

So take the test 4 times to be sure?

I bet the covid test might be wrong more then half the time.

Just like the numbers being reported in FakeNewsCNN

The Dems: Let’s blame Trump!

Minnesota rioters should be in quarantine 14 days.

Oh but you march to the drum of the big Dems screaming “testing testing testing” all over Twitter still. How about you educate your puppeteers?

Still, that's a better percentage than CNN being right about anything.

Fitting the left narrative once again.

Coronavirus: “Half the time it works every time.”

Stay true.

Always creating panic as an opportunity. Guess who?

Race Is On to Create Rapid Covid-19 Tests for the FallAs businesses and consumers come out of lockdowns, many think a key part of the solution is quick diagnostic testing that doesn’t require specialized labs. Yet experts estimate access to quality rapid tests is months away. 10 bucks or I yell. Great from a medtech perspective but this will be a workplace privacy and inclusion polemic in the US.
