Gonorrhea NAAT in Kathmandu
- NAAT ~95% — diagnostic standard on correct specimen.
- ~85–90% extragenital off urine — coverage constraint.
- ~1–2 week window — earlier is inconclusive.
- Curable — ceftriaxone-based where found.
NAAT — the Molecular Gonorrhea Test
NAAT (nucleic acid amplification — the PCR-based molecular method) is diagnostic standard for gonorrhea — ~95%+ sensitive and specific on correct specimen — detecting organism's genetic material directly.
The specimen determines what the NAAT can see: first-catch urine covers urethral infection; a throat swab covers pharyngeal; a rectal swab covers rectal — ~85–90% of extragenital gonorrhea is outside what urine can detect. The commonest NAAT error is a urine-only test for a multi-site exposure — correct method on wrong specimen.
The window is ~1–2 weeks — organism must reach detectable levels — and infection is curable with ceftriaxone-based therapy where test finds it.
The NAAT — What It Detects
The NAAT amplifies gonorrhea organism's genetic material — detecting it directly at ~95%+ sensitivity and specificity — on whatever specimen is provided. The test is reliable where specimen is correct.
Usually run as combined CT/GC NAAT ( organisms travel together — tested together), result reports each organism separately.
NAAT ~95%
Sensitive and specific — on correct specimen.
Combined CT/GC
Usually tested together — each reported separately.
Detects DNA
The organism's genetic material directly.
Specimen Decides
Reliable where specimen is correct.
The Specimens — Matched to the Exposure
The specimen determines coverage: first-catch urine detects urethral; throat swab detects pharyngeal; rectal swab detects rectal — site-matched coverage that determines what test can see.
~85–90% of extragenital gonorrhea is at throat or rectum — sites urine cannot see — commonest testing error is urine-only where exposure included oral or anal sex.
First-Catch Urine
Urethral — commonest but not complete test.
Throat Swab
For oral-sex exposure — missed site.
Rectal Swab
For anal-sex exposure — missed site.
~85–90% Missed by Urine
Most extragenital infection is off default.
The ~1–2 Week Window
The NAAT is reliable from ~1–2 weeks post-exposure — earlier, organism may not have reached detectable levels and negative is inconclusive. For a specific recent exposure timing is discussed rather than reflexively testing too early.
Symptoms where present appear ~1–2 weeks after — but most extragenital infections are asymptomatic — reason site-matched testing exists.
~1–2 Week Window
Reliable detection — earlier is inconclusive.
Symptoms ~1–2wk When Present
Discharge, burning — or nothing.
Extragenital Mostly Silent
Throat and rectal usually asymptomatic.
Retest Where Early
The definitive test at right interval.
The Treatment Pathway
A NAAT positive is treated at same visit — ceftriaxone-based ( correct drug for resistance landscape) — with partner management (partners tested site-matched and treated) and pharyngeal test-of-cure where indicated.
The interpretation is complete: positive specifies site (urethral, pharyngeal, rectal — each found on its specimen), treatment is same across sites, and follow-up is matched to site.
Ceftriaxone-Based
The correct drug — resistance-aware.
Same-Visit Treatment
Where positive — prescribed at consultation.
Partner Treated
Tested site-matched and treated.
Pharyngeal Test-of-Cure
~1–2 weeks — clearance less certain.

Frequently Asked Questions
What is a gonorrhea NAAT?
The molecular test — ~95% on correct specimen — detecting organism's genetic material.
Is a urine test enough?
Only for urethral — throat/rectal exposures need swabs; ~85–90% of extragenital infection is off urine.
When can I test after exposure?
~1–2 weeks — earlier is inconclusive.
Is gonorrhea curable?
Yes — ceftriaxone-based; drug choice matters for resistance.
Do partners need testing?
Yes — tested site-matched and treated.
Is it confidential?
Yes — private testing and results.
