It is possible to get tested for sexually transmitted infections (STIs) after unprotected sex, but the timing may vary depending on the specific STI. Some STIs, like Chlamydia, can be detected after at least 14 days, while others, like Gonorrhea, can be detected after 7 days. It is recommended to wait at least 14 days before getting tested for both Chlamydia and Gonorrhea. It is also important for both partners to get tested, as one partner may be a carrier of an STI without showing symptoms. Other STIs, like Hepatitis B and C, Syphilis, and HIV, may require a longer waiting period of up to 3 months before they can be detected. Testing methods may include a vaginal or cervical swab for Chlamydia and Gonorrhea, and a blood test for other STIs.
