Connecticut notes

  • Minors can consent to their own STD testing and treatment in Connecticut without a parent’s permission.
  • Expedited partner therapy is permitted in Connecticut for chlamydia and gonorrhea.
  • Students: Yale, Southern Connecticut State, Quinnipiac, Fairfield, and Sacred Heart all have student health services; a private walk-in lab keeps results off university and family insurance records.

When to test

Chlamydia and gonorrhea at 2 weeks after exposure, HIV and syphilis at 6 weeks, herpes antibody at 12 weeks. With symptoms, test now and retest after the window.

Which tests to order

The 10-test panel ($139) covers the common infections in one visit. After one known exposure, chlamydia and gonorrhea together ($99) at two weeks and HIV plus syphilis ($49 each) at six weeks is a reasonable minimum.

Testing with a partner in New Haven

A lot of people get tested as a couple, at the start of a relationship or before stopping condoms. It works the same way as testing alone, just twice: each of you places your own order, so each of you gets your own private results, then you can walk into the same lab together and be done in about ten minutes.

  • Same tests, same day. Ordering the same panel for both of you keeps the results easy to compare. The 10-test panel is the usual choice; add trichomoniasis if you have vaginal sex.
  • Results are individual. Neither of you can see the other's results unless you share them, which is worth agreeing on before you test.
  • If one of you tests positive, treat both of you at the same time for chlamydia, gonorrhea, or trichomoniasis, even if the other person tested negative, or the infection passes back and forth. Retest in 3 months.
  • A positive result is not proof of recent cheating. Chlamydia, trichomoniasis, herpes, and HPV can go unnoticed for months or years.
