Taking biotin supplements matters in relation to AccessBio’s rapid antigen tests because high levels of biotin can skew results for antigen tests. False negatives for the AccessBio CareStart rapid antigen test may occur for test takers that currently take a daily dose of Biotin >10 mg. Biotin levels of 2.5 µg/mL have been demonstrated to result in false negative test results.
The health questionnaire question about Biotin only affects our AccessBio rapid antigen test offering. If you only participate in individual or pooled PCR testing, this question does not apply to you.
