To get results back for an STD test that requires laboratory testing usually takes about a week, according to Rutgers Medical Services. Not all tests for STDs require laboratory testing, however, and with some tests, such as rapid-testing for HIV, results are available almost immediately.
Testing for STDs includes tests for HIV; gonorrhea; syphilis; hepatitis A, B, and C; and herpes, reports Rutgers Medical Services. The testing recommended depends on factors such as the patient's sexual history. Blood tests are required to test for the presence syphilis and hepatitis A, B and C. Other tests, such as those for gonorrhea and chlamydia, are performed using a urine sample.
