Accurate Testing in Kathmandu
- ~95% on correct specimen — the NAAT standard.
- ~85–90% extragenital off urine — coverage constraint.
- Site-matched = accurate — specimens matched to exposure.
- ~1–2 week window — earlier is inconclusive at any accuracy.
Accuracy = Coverage for Gonorrhea
The most accurate gonorrhea test is NAAT on correct specimen — ~95%+ sensitive and specific — but accuracy is determined by specimen coverage, not just method: a urine NAAT covers urethral infection; a throat or rectal swab covers those sites — the ~85–90% of extragenital infection that urine cannot see.
The "accurate" that matters is complete coverage: a urine test alone is accurate for urethra but misses throat and rectum — accurate test for a multi-site exposure is site-matched combination, not single-specimen version.
The window constraint applies too: ~1–2 weeks post-exposure — an accurate method at a wrong timing is an accurate inconclusive.
The Method — NAAT ~95%
NAAT is diagnostic standard — ~95%+ sensitive and specific on correct specimen — detecting organism's genetic material directly. Usually combined with chlamydia ( organisms travel together — tested together).
The method is accurate where specimen is correct — the NAAT's ~95% is on right site; on wrong site (a urine test for a rectal infection) accuracy for that site is zero.
NAAT ~95%
Sensitive and specific — on correct specimen.
Combined CT/GC
Usually tested together — each reported separately.
Molecular
Detects organism's genetic material directly.
Specimen Decides
The accuracy applies to sampled site.
The Coverage — Site-Matched
The specimen determines coverage: first-catch urine for urethral; throat swab for pharyngeal; rectal swab for rectal — each covering its site. ~85–90% of extragenital infection is at throat or rectum — sites urine test cannot see.
The accurate test is site-matched combination where exposure warrants — specimens that cover sites exposure involved.
First-Catch Urine
Urethral — urethral specimen only.
Throat Swab
For oral-sex exposure — missed site.
Rectal Swab
For anal-sex exposure — missed site.
Site-Matched = Accurate
The coverage exposure requires.
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 regardless of method's accuracy.
The honest timing guidance: for a specific recent exposure, the ~1–2 week interval is correct timing — an accurate test at a wrong timing is an accurate inconclusive.
~1–2 Week Window
Reliable detection — earlier is inconclusive.
Accuracy Unaffected
An accurate method at wrong timing is still inconclusive.
Correctly Timed
The accurate test at right day.
Retest Where Early
The definitive test at interval.
The Interpretation
A NAAT positive on correct specimen at right timing is definitive for that site — a urine positive is a urethral positive; it does not claim throat is negative. A negative is read against coverage and timing.
The interpretation is accuracy's final link: result read against exposure — which sites were involved, which test covered, what timing allows — and answered with what it means.
Positive = Definitive for Site
A urine positive is a urethral positive.
Negative Read Against Coverage
What test did not sample is not excluded.
Window-Aware
The timing determines what a negative means.
Interpreted in Context
The result with exposure in view.
