PCR/NAAT Testing in Kathmandu
- NAAT ~95% — molecular standard for CT/GC.
- Lesion PCR ~95% — acute herpes diagnostic ~2–12d.
- Specimen decides — coverage test can see.
- Window applies — ~1–2wk CT/GC; ~2–12d lesion.
PCR/NAAT Testing — the Molecular Methods
The PCR and the NAAT are molecular methods — pathogen's genetic material detected directly (the DNA/RNA amplified and detected — the ~95% sensitivity on correct specimen, current standard for bacterial infections and lesion diagnostics).
The NAAT is standard for bacterial (the CT/GC — ~95% on site-matched specimen); the PCR is acute diagnostic for herpes ( lesion PCR ~95% on a fresh sore ~2–12d). The molecular methods detect organism's genetic material rather than culture or antibody.
The honest framing: molecular methods are correct standard for what they detect — but specimen decides what test can see ( site-matched collection — the ~85–90% extragenital urine-only misses), and window determines timing (the ~1–2 week CT/GC, the ~2–12d lesion).
The Molecular Methods — NAAT & PCR
The NAAT is molecular standard for bacterial infections — the CT/GC detected by organism's genetic material (~95% on correct specimen) — more-sensitive than older culture methods.
The PCR is acute diagnostic for herpes — lesion PCR on a fresh sore (~95% within ~2–12 days) — direct detection on shedding virus where lesion is present.
NAAT ~95%
The molecular standard for CT/GC.
Lesion PCR ~95%
The acute herpes — ~2–12d on a fresh sore.
Genetic Material Detected
The DNA/RNA — direct detection.
More Sensitive Than Older
The molecular vs culture/antibody.
The Specimen Decides — the Coverage
The molecular method detects organism's genetic material on specimen collected — site-matched collection determines what test can see: urine for urogenital, throat swab for oral-sex exposure, rectal swab for anal — the ~85–90% extragenital urine-only misses.
The honest framing: the NAAT is ~95% on correct specimen — a NAAT on wrong specimen ( urine-only for a throat infection) is a NAAT miss, not a NAAT answer — site-matching is coverage that determines value.
Site-Matched
The specimens matched to exposure.
~85–90% Extragenital
The throat/rectal urine-only misses.
Coverage the Value
The site-matching determining what test sees.
Wrong Site = Miss
The molecular method on wrong specimen.
The Windows — the Timing
The NAAT window is ~1–2 weeks for CT/GC — organism needs that interval to reach detectable levels — earlier is inconclusive. The lesion PCR window is ~2–12 days — acute period where sore is shedding — fresh lesion is diagnostic opportunity.
The honest timing: molecular method at correct interval is reliable detection — too-early molecular test is molecular inconclusive — timing is biological.
~1–2wk CT/GC
The NAAT window — bacterial detection.
~2–12d Lesion
The PCR window — acute herpes.
Inside = Inconclusive
The timing is biological — not method.
Correct Timing Reliable
The interval determining accurate answer.
What the Molecular Methods Do Not Cover
The molecular methods detect specific organisms they test for — the NAAT for CT/GC, the PCR for herpes — not reflexively other infections: syphilis is serology ( antibodies, not molecular on routine), the HIV is the 4th-gen serology or the RNA ( different method).
The complete screen is combination — molecular for the CT/GC/lesion, serology for the HIV/syphilis/hepatitis — correct method for each infection, not a reflexive PCR for everything.
NAAT for CT/GC
The molecular for bacterial.
PCR for Lesion
The acute herpes direct detection.
Serology for the Viral
HIV, syphilis, hepatitis — antibodies/antigens.
Complete = the Combination
The correct method for each infection.
