Chlamydia Testing: Everything You Need to Know
Content last reviewed 2026-09-12 · Educational information — not medical advice
Quick answer
Chlamydia testing uses a urine NAAT — no swab required for most people. It's the most-reported infection in America, half of cases have zero symptoms, one lab visit plus 1–3 days gives answers, and a short antibiotic course cures it completely.
What is a chlamydia test?
A nucleic-acid amplification test (NAAT) detects chlamydia trachomatis DNA in a urine sample or swab. Urine NAAT is the standard for men and increasingly for women; vaginal swabs (self-collected or provider-collected) run equally well. Blood tests CANNOT detect chlamydia — it's a localized genital infection, not systemic.
What are chlamydia symptoms — and what if I have none?
That's the trap: roughly half of men and three-quarters of women feel nothing. When symptoms appear: burning urination, discharge, testicular pain in men; discharge, bleeding between periods, painful intercourse in women. Silent progression to PID remains the serious female risk — which is exactly why annual screening under 25 is CDC-standard regardless of symptoms.
How do I get tested?
Order a urine NAAT online (direct-access), give a first-catch urine sample at any patient service center — no fasting, no examination, no swab unless throat/rectal exposure needs site-specific testing. Results land in your portal within 1–3 business days. County health departments provide the same test free.
When after exposure should I test?
Window period runs 1–2 weeks post-exposure for reliable NAAT detection. Testing at day 3 can miss establishing infections. Symptomatic? Test immediately regardless of timing. Treated? Re-test 3 months later — reinfection rates are high enough that CDC makes follow-up standard.
What does treatment involve?
Single-dose azithromycin or a week of doxycycline cures it — partners must treat simultaneously (expedited partner therapy lets clinicians prescribe for them without visits in most states). Skip sex until both complete treatment. Untreated chlamydia never reliably self-resolves.

Frequently asked questions
Will chlamydia show up in a normal urine drug test or UTI test?
No — routine urinalysis and drug screens don't detect it. Only a specific NAAT ordered for chlamydia works.
Can chlamydia come back after treatment?
Reinfection from untreated partners is common — that's different from treatment failure and why 3-month retesting exists.
