Possibly, but it depends on the antibiotic and the infection being tested. Antibiotics won't affect testing for HIV, herpes, or hepatitis. The only STD tested by blood that might possiblyby affected by antibiotics is syphilis, and the effect would depend on the type of test. Contact your health care provider for advice specific to your situation.
