I gave blood on Friday and there wasn’t anything unusual (other than having my temperature taken before I could enter and having to wear a face mask). So if they tested me for Covid antibodies I wasn’t aware of it—perhaps they ran a test on the blood in one of the little tubes they fill up at the end.
Well, guess it doesn’t matter. I spoke with a super-smart science guy and he said the antibody tests are pretty worthless. Oh well...
