Where around BR to get antibody test?

They only do the blood draw one

This, I donate platelets every other week. I've been tested for antibodies 5 times this summer.

you are wasting your time. these tests were rushed past the normal regulatory hurdles. they have not been evaluated against the many many factors that can affect the performance of the test. Some of these factors are age, sex, underlying conditions, diet, herbal/vitamin intake, medications, etc, etc, etc. These antibody tests are just too unreliable to yield any useful info.

Oh, misread your OP. Onsite Medical on Hwy 30 in Gonzales does them for $60. I don’t think they’re that accurate tho

Relief TeleMed is doing them for $49 and only took 30 minutes for my results. Got mine done by them last week.
