Unbeknown to many people, STDs have a detection window in which they can be detected in STD tests. Most STDs cannot be detected for days, if not weeks, after initial exposure. For this reason, it’s important to understand what these time periods are. Also make sure to keep in mind the fact that your first “negative” test might not be completely accurate due to these detection windows.

STI/STD Testing Window
Chlamydia 1-4 Weeks
Gonorrhea 1-3 Weeks
Hepatitis C 4-12 Weeks
Herpes Simplex 1 & 2 2-16 Weeks
HIV Antibody Test 3-12 Weeks
HIV Early Detection Test 1-4 Weeks
Trichomoniasis 5-7 Days
