Have heard that a T-Cell test exists and can be taken if you are of a mind. It costs $150.00 (?) and is said to be accurate in that false negatives and false positives are generally not a problem with this test. A positive result definitively demonstrates immunity to SARS-CoV-2 even if an earlier antibody test came up negative.
