From what I am hearing from people who were positive recently, it never was positive on the rapid, to the extent that maybe the rapid doesn't pick up the delta variant, or which ever one it was (not that it was extensive research, but 4-5 people that I know of personally).
I know a couple who had it over succos, 1 rapid was positive and 1 negative, both were positive on pcr
Workflowy. You won't know what you're missing until you try it.

My wife tested positive on rapid and PCR last week.

Very anecdotal, the false negative rate could be as high as 25%. Though it's certainly possible that the published false negative rate was assessed before the Delta variant was pervasive and it should be reassessed.

I was vaccinated (Pfizer) in March 2021, just tested Friday came back 1002.0. In no rush for a booster.

Labcorp test 164090 is a Roche quantitative ECLIA spike antibody test that can check for COVID antibodies from infection or vaccination with 100% Specificity. My high deductible insurance covered it in full. Anything above 0.7 is considered positive.

I had COVID (undiagnosed, with symptoms but with no loss of smell/taste) in February 2020. In January 2021 I got this test and my numbers were 192.6. I got vaccinated in March, but didn't retest afterward.

My father had the test done before his vaccine and was 0. He got tested again 2 weeks after his 2nd Pfizer shot. At the time the top number of the test was 250 and he tested greater than 250.

My 10 year old Rafi had COVID (diagnosed, with symptoms but with no loss of smell/taste) in November 2020. In July 2021 he got tested and his numbers were 478.4. Apparently the upper range of the test has gone up.

Post your own DPs if you took this titer.
The upper range on this test has been increased to 2,500 and the cost for an Rx has gone down to $6 if you don't have one from a Dr.

I took a titer yesterday, 7 months after my 2nd Moderna shot and 21 months after having COVID and my numbers are now greater than 2,500:




DW took it 7 months after her 2nd Moderna shot and was 1,156. She tested negative for antibodies before she vaccinated.



Given that neither of us are immunocompromised and we're in our 30s, we're not planning on getting a booster in the near future.

Are you curious at all about your N-protein antibodies?

And again?



This is why I wouldnít rush to get a booster even if Iím eligible.

Where do you get this in CH?
I've been waiting over 5 years with bated breath for someone to say that!

Dr. Rosen's office. I was there for something else and asked to have it done, so the PA drew a tiny amount of blood into a vial for it. But I think for some insurances they sent to Quest which has a completely different semi-quantitative test.

You asked specifically for the Roche test?

I asked for the semi-quantitative Labcorp test and gave the test number in the OP, though it didnít seem necessary.
