Will being on a antibiotic give you false positive pregnancy test?

The use of antibiotics does not typically interfere with the accuracy of pregnancy tests. Pregnancy tests, including home pregnancy tests and laboratory-based tests, detect the presence of a hormone called human chorionic gonadotropin (hCG) in the urine or blood. Antibiotics specifically target and kill or inhibit the growth of bacteria and do not cross-react with hCG or influence its levels in the body.

It's worth noting that certain medications, such as fertility drugs containing hCG, can cause a false positive result on a pregnancy test. However, antibiotics generally do not contain hCG and therefore should not lead to false-positive results.

If you are taking antibiotics while pregnant or suspect you may be pregnant, it's always recommended to discuss any concerns or questions with a healthcare provider. They can guide you and provide further clarification based on your specific situation and medical history.
