Which of the following tests is NOT part of the standard sexual health checkup for asymptomatic patients?

The standard sexual health checkup for asymptomatic patients typically focuses on screening for sexually transmitted infections (STIs) that are most prevalent and pose a significant risk to public health. Tests for HIV, chlamydia, and gonorrhea are commonly included in these checkups because they are among the most frequently reported STIs and can have serious health implications if left untreated.

Hepatitis A, while it is a viral infection that can be transmitted sexually, is not routinely screened for in asymptomatic individuals during standard sexual health checkups. The primary mode of transmission for Hepatitis A is through fecal-oral contact rather than sexual activity, making it less significant in the context of routine sexual health screening compared to other STIs.

Therefore, Hepatitis A is not part of the standard set of tests performed on asymptomatic patients during sexual health checkups, which is why it is the correct answer in this context.
