Can you get your antibody levels tested for vaccine

immunity purposes, and how?

A recent poster had this checked which is partly why I'm asking.

Does it require a doctor's recommendation, and is it done because a person has an autoimmune disorder or other medical condition, or you think you have Covid or were exposed to it?

I'm curious to know my levels if possible.

I had both Moderna shots and intend to get the booster later this month.

Thanks.

1. I could be wrong, but think that poster is part of a test group.

4. You're right, I recall that now. The poster was in a

test/study group. I searched but couldn't locate the article.

2. Yes. My stepdaughter is having one today as the first was inconclusive.

I believe a doctor has to order it as was the case for us.

3. Outside research facilities, the antibody tests are qualitative... is antibody detected-- without

the quantification necessary to provide much meaningful information as to whether the antibody is present at levels likely to be sufficiently neutralizing. Somewhere there may be a commercial test being marketed, but it would be quite expensive and still questionable. Validation of the precise level of antibodies necessary to be sufficiently protective is difficult outside large population-based research studies, may vary from individual to individual and doesn't begin to address the non-alpha and non-delta variants.

So yes, you can get a test that gives you basic information that you have some level of measurable antibodies. And, if you do, it is likely you have activated b- and t-cells ready to ramp up if necessary, should the antigen present in an exposure--at least against delta. Beyond that, though they can't tell you much more than that; however, those tests are useful for the immunocompromised, as even some degree of measurable antibody is meaningful.

about this subject and answered several questions. Merci.
