I got covid last January, but was never tested for it. I just assumed that's what it was since my wife was tested and did have it. She had the whole deal, fever, etc. Mine was like a cold. So last July, 6 months later, since I wasn't tested and didn't know for sure, I got antibody tested. I had them and it was 248.9.
So I went back yesterday after a year to see if they were still there after the pharmaceutical companies saying they diminish over time, you need boosters etc. So I got tested Tuesday and got my results yesterday:
361. So they either increased, or it's just a % error in testing, or I got covid again and didn't know it. Just thought I would pass along this valuable information to you.
