unfortunately there doesn't seem to be Antigen Testing in my area. All google searches pop this antibody testing. I am concerned about my wife. I had this test 3 weeks ago to see if 4th shot would help. My pharmacist said since my antibodies were >2500 I was as good as it gets. SARS-CoV-2 Semi-Quant Total Ab >2500.0 (current result) U/mL (Units) Negative<0.8 (reference interval)
