Did you test for antibodies? POLL

Where did she take this test? How can someone obtain a test with 99%+ specificity in Lakewood?

Take any test to a photoshop expert, and they'll make it whatever you want it to be.

CMIIW, but I believe the specificity for a positive result on many tests is at least in the upper 90s.

So are people who took the old mayo test getting themselves retested?

My wife was negative at bikur cholim, redid cause I and my 2 kids were positive.
Redid by CHemed and still negative.

Which practices are administering those? I’m not trying to argue I genuinely want to know

Is Labcorp using Roche?
Or only in some locations? How can you tell?

I tested negative for bikor Cholim/mayo and results said negative.
I had a cough for a few days after Purim and was exposed on Purim to many many people who got it.
Got retested at a local urgent care in Flatbush which used labcorp/Diasorin. I got a 10 and needed a 15 to be considered Positive.

I’m confused the bikur cholim/mayo tests isn’t accurate? False positives?

The previous test they have been using is not very accurate.

Just read it upthread it was testing for shells not the spikes ..not sure y that’s a negative tho

It failed to receive FDA EUA.

It failed to receive FDA EUA.

Failed to receive or didn't apply?

Freaking weird!! Me and wifey just got tested for Antibodies. My entire family including myself was sick with Corona a month ago. Her test came back positive for Antibodies mine Negative!! And I had much worse corona symptoms then her ...weird !

The submission is public. Probably failed because specificity was too low.

Very weird! Who would have thought different people react differently to Coronavirus?! It takes time for antibodies to show up on blood tests & the most of the tests show a lot of false negatives

If I want to get tested for antibodies, where in Brooklyn would you recommend going, and why?

Abbott and Roche seems like the gold standard.

[Traveler718]

Abbott and Roche seems like the gold standard.

Thanks, any advantages of one over the other, in terms of accuracy, and getting an actual antibody count as opposed to just positive/negative? And does anyone in Brooklyn know of a place that uses the Abbott or Roche tests?

They're both qualitative only tests, so just positive/negative.
Quest does Abbott.
Labcorp it seems you may be able to order specifically Roche by having orders for 164068 SARS-CoV-2.

[Dan]

The Abott test which is prevalent has 99% specificity which gives an 84% Predictive value according to the FDA.

The German made Euroimmune & Roche tests do indeed have 100% specificity, which give a 100% Positive predictive value (and the FDA notes that in the link you posted).

The Forbes article is complete bogus.


ETA I made a mistake. While Euroimmune does have 100% specificity (80/80), Roche only has 99.8% (5262/5272), so the FDA calculates their PPV at 5% prevalence as 96.5%.

I spoke to Euroimmune and their test is readily available in German labs. I doubt it's actually better than Roche though.

Roche is now available at Labcorp:
"If test code 164068 SARS-COV-2 is ordered it will be by Roche"

now the question is if i can write myself a script for it. wanna make sure it's exact
