You may have questions about when to get tested for sexually transmitted diseases (STDs) if you're sexually active, especially if you have multiple partners. You can have an STD without knowing it, which is why getting tested is important. It is common for symptoms to be absent in many cases. Due to the fact that you can have an infection without showing any symptoms, many experts prefer the term sexually transmitted infections (STIs). There is no pain associated with STD testing, and it is quick and easy. Each STD has its own test, so there is no single test for all STDs. You can discuss which tests you need with your doctor. A full screening may include a urine test, a cheek swab, a physical exam, and a blood test. Your sores may also be tested, as applicable, through the extraction of a sample fluid. A swab may be used to take cell samples from a potentially infected area, such as the genitals, as well. An STD panel may also be conducted.
