How Accurate is a Rapid STD Test?

Rapid STD tests are generally accurate, with sensitivity rates ranging from 85-99% depending on the specific test and infection. HIV rapid tests achieve 99% accuracy, while chlamydia and gonorrhea rapid tests typically show 85-95% sensitivity. However, accuracy varies significantly based on timing, with tests potentially missing infections during the window period when antibodies or antigens haven't developed sufficiently. False negatives are more common than false positives, particularly if testing occurs too soon after exposure. Most rapid tests require confirmation with laboratory-based testing for positive results. The convenience of same-day results makes rapid testing valuable for initial screening, but healthcare providers often recommend follow-up testing for comprehensive STD screening.
