Tests for COVID-19 can be hard to come by, but there are dozens of tests on the market that test for antibodies. Most antibody tests on the market got emergency usage approval and are not FDA approved, pathologists say, so the frequently produce false positives. “Maybe 60, 70% of the tests that have hit the market are unreliable,” said Dr. John Heydt of KPC Health Global. Just this week, two more antibody tests have hit the market and are considered to be much more reliable, and both are FDA approved — the Roche Test and the Abbott Labs serum serological test. Heydt says OC Global Medical Center will begin using the Abbott Labs test, which can tell patients if they’ve been exposed and when they got the infection.
