I give blood regularly, the regional hospital that runs the blood lab has in the past run antibody tests on me at least 2 times. The test is an “unapproved” test and each time I checked negative for Covid antibodies.
My wife and I think we may have had it early in the original outbreak. If we did, it was a mild case. We have since been exposed when my father was diagnosed with it, we have not had any sign of infection.
The last time I gave blood, I asked the lady that asked me all the questions about my history, if she had thought about the future of giving blood after Covid, and had she thought that possibly next year they might be asking if I ever had the mRNA vaccination? She did not answer directly, but I think she had considered it.
Take the PCR test, it can find anything....even if it’s not there...
I had a bunch of blood tests by my doctor as part of my 5 year “annual” check-up in the beginning of August. I asked they include the covid anti-bodies test.
It came back i had almost twice the amount of anti-bodies necessary to produce a positive result. You need 1.4 for a positive test, mine was 2.6 (H), the H meaning High. The doctor could not believe i did not get vaccinated. I may have had covid in March, 2020, but when i got tested back then it came back negative.
