Do you know which hiv test take after one month exposure.. i had unprotected sex with prostitute?

Multiple tests: After exposure to HIV or after high risk behaviors (like unprotected sex) it is recommended that you have multiple tests performed. You should be screened for other stis, like chlaymydia, gonorrhea and syphilis as well. Hiv and syphilis are blood tests that should be tested multiple times over the next 6 months to ensure that you didn't contract either infection.
