Overview
STI urine testing uses first-catch urine for NAAT detection of chlamydia and gonorrhea. It is convenient and less invasive for many patients.
What it detects
Chlamydia and gonorrhea nucleic acid.
Sample type
First-catch urine.
When it may be appropriate
Routine screening, discharge or urinary symptoms.
Window period considerations
Can detect infection relatively early, but very recent exposure may need repeat testing.
Test limitations
Does not detect all STIs; extragenital infections may require swabs.
Interpretation basics
Positive results support infection; negative results depend on timing and site.
Follow-up recommendations
Treat positive results and consider broader testing if symptoms persist.
