Sexual Health

An STD test window period is the gap between exposure and when a test can reliably find the infection. Test too early and a negative can be false. As a guide: chlamydia and gonorrhea from 1 to 2 weeks, 4th generation HIV tests from 18 to 45 days, syphilis from 3 to 6 weeks. A doctor can confirm your timing.

You can get a confidential STD test in Koh Samui at Doctor Samui, a 24/7 walk-in clinic on Chaweng Beach Road with its own lab. A full panel covers HIV, syphilis, chlamydia, gonorrhea, and hepatitis. PEP for HIV must start within 72 hours of exposure. Results stay private, and treatment is available on site.
