How do you get tested for std?

Depends on the STD: Syphilis is diagnosed with a blood test. Gonorrhea and chlamydia are diagnosed either with urine tests (for urethral or cervical infections) or from swabs taken from the vagina, rectum, or throat. The swabs can be sent for culture, dna probes, or nucleic acid amplification tests (naats). Those are the "big 3, " but there are other stds.

Different: Different tests. Some are blood tests, some are swabs, and cultures.

After unsafe sex: you are at risk after unprotected sex particularly if it is anonymous. The number of partners increases the risk. Symptom of discharge or burning urination or ulceration are strongly suggestive. Consider these. Go for an evaluation if you feel at risk. If you want to switch to a monogamous relationship go with your partner.
