Can a UTI cause ngu? Std test was negative.

Can a UTI cause ngu? Std test was negative.

NGU is STD, UTI isn't: Urinary tract infection (UTI) and nongonococcal urethritis (NGU) are separate problems. But some doctors don't know the difference and diagnose UTI in men with NGU.

A bit too early: The exact time for reliable chlamydia testing by NAAT isn't certain, but 3 days probably is a bit early. A negative result would be somewhat reassuring, but probably not conclusive. It would be safer to wait until 5 days or so, unless there is some urgency (e.g. if you have abdominal pain or other symptoms of a complication like PID). ...Read more
