I am currently taking a course of antibiotics and have received a Roche blood sample antibodies test. Should I wait until I’ve finished the antibiotics before doing/sending the small sample of blood they require?
Antibiotics should not affect your COVID-19 test. Antibiotics are effective against bacterial infections and don’t treat viruses. COVID-19 is a virus and so the viral antibody test targets antibodies against the spike protein, therefore you can still be tested for COVID-19 antibodies when on antibiotics and it should not interfere with the result.
