A blood test is used to detect HIV, Hepatitis A, B, and C, Herpes, and Syphilis. If you’re taking an at-home test, you only need to provide a finger-prick blood sample.
Other common STDs, including Chlamydia, Gonorrhea, and Trichomoniasis require a urine sample. Vaginal or anal swabs may also be required for some STDs, alongside a blood or urine test.
