The STDs and STIs that can be easily tested for are chlamydia, gonorrhea, hepatitis, herpes, HIV and syphilis. There is no single, universal test that covers all possible STDs and STIs, as each STD and STI has its own testing requirements. A comprehensive series of tests may involve a urine test, a cheek swab, a blood test, a general physical checkup, fluid tests from sores and a swab test to check any discharges. You may also need to have different tests done depending on the types of sexual intercourse you have engaged in, the number of partners you have been sexually active with and how often you use protection. It is important to be honest with your doctor when asking for a test so you can receive the right tests and receive the right treatment.
