Testing Standards in Kathmandu
- Method varies by lab — "chlamydia test" can mean PCR or a weak antigen kit; always ask.
- Panel pricing varies wildly — hospital MRP vs. molecular-lab rates differ by multiples; we quote honestly before drawing.
- Window periods are routinely ignored — early negatives sold as final.
- Site sampling is rare — rectal and pharyngeal testing is offered here as routine, not exception.
Testing Everything, Properly
STD testing fails in predictable ways: the wrong method (rapid antigen instead of PCR), the wrong site (urine only after multi-site exposure), the wrong time (inside the window period, read as conclusive), or the wrong scope (one test when the risk called for a panel). A good testing center prevents all four errors — that is the entire job.
At Thamel Clinic, testing is physician-directed: a brief confidential history selects the tests, samples and timing that actually answer your question. PCR/NAAT for bacterial and parasitic STIs, serology with proper pairs for syphilis, 4th-generation Ag/Ab and RNA PCR for HIV, and hepatitis B/C serology — combined into single-visit panels where it saves you money.
This page covers what to test for, which methods we use, window periods per infection, and how results are delivered.
What Should You Actually Test For?
The right scope depends on your situation — but the usual frameworks are:
Core panel (routine screen)
Chlamydia + Gonorrhea PCR, Syphilis RPR/TPHA, HIV 4th gen Ag/Ab — covers the four major treatable STIs.
Extended panel
Core + Hepatitis B & C — adds the blood-borne viruses; standard for thorough screening.
STI-29 PCR panel
Comprehensive molecular panel — trichomonas, mycoplasma, ureaplasma, gardnerella and more from combined samples.
Symptom-directed
Ulcer → syphilis + herpes; discharge → gonorrhea/chlamydia/trichomonas; warts → examination. Symptom-matched, not blanket.
Site-complete
Rectal + pharyngeal PCR swabs added when exposure includes anal/oral sex.
Post-exposure timed
RNA PCR for early HIV detection; staged serology schedules where the window has not closed.
Methods We Use — and Why
- NAAT/PCR for chlamydia, gonorrhea, trichomonas, mycoplasma — ~95–99% accuracy; the diagnostic standard.
- HIV 4th-gen Ag/Ab — conclusive at 45 days; RNA PCR for the earliest detection (~10–33 days).
- Paired syphilis serology — RPR/VDRL titer + treponemal confirmation, always together.
- Hepatitis B/C serology — HBsAg and anti-HCV with reflex confirmatory testing.
- Culture when it counts — antibiotic sensitivity testing for suspected gonorrhea resistance.
- Clinical examination — warts, herpes lesions and molluscum diagnosed visually by the doctor.
Window Periods, Per Infection
- Gonorrhea: ~1 week (PCR).
- Chlamydia: ~1–2 weeks (PCR).
- Syphilis serology: ~3–6 weeks; earlier with lesion testing.
- HIV 4th gen: 18–45 days; conclusive at 45.
- HIV RNA: ~10–33 days — earliest option.
- Hepatitis B/C: ~4–10 weeks / ~6–9 weeks for reliable serology.
- Testing inside a window is fine — but the negative gets scheduled for confirmation, not filed as final.
A Testing Visit
- Brief confidential history → test selection matched to your exposure.
- One sampling session — urine, swabs (self-collect option), single blood draw.
- Results in 24–48 hours (serology same-day to 48h; PCR 24–48h).
- Doctor interpretation included — what the result means, not just what it says.
- Positive results convert to same-visit treatment plans.
Testing Options & Indicative Costs
| Service | What It Includes | Cost (NPR) |
|---|---|---|
| Consultation & test selection | Right tests, right sites, right timing. | Rs. 450 |
| Single PCR (GC or CT) | Per-pathogen NAAT, any site. | Rs. 6,000 – 10,000 |
| Core 4-infection panel | GC/CT PCR + syphilis paired serology + HIV Ag/Ab. | Package — call |
| STI-29 PCR panel | Comprehensive molecular screen. | Package — call |
| HIV RNA PCR | Earliest detection option. | Rs. 7,000 – 12,000 |
| Hepatitis B/C screen | HBsAg + anti-HCV serology. | Rs. 1,500 – 3,500 |
Combined panels cost less per infection — call for package rates.
Why This Is the Best Testing Center
- Physician-selected testing — no wasted panels, no missing sites.
- PCR-accurate methods — gold-standard diagnostics as default.
- All anatomical sites — rectal and pharyngeal offered routinely.
- Honest window guidance — negatives dated and scheduled for confirmation.
- Single-visit efficiency — one draw, one urine set, done.
- Results with interpretation — a doctor explains; you decide next steps.
Frequently Asked Questions
Can one visit cover all STD testing?
Yes — a single session covers urine/swab PCR plus the blood draw for syphilis, HIV and hepatitis. The doctor selects the panel your history actually needs.
How accurate are the tests?
PCR/NAAT runs ~95–99%; HIV 4th-gen is conclusive at 45 days; syphilis uses paired serology because single tests mislead. Method selection is why accuracy here is high.
I tested last week after an exposure — was it too early?
Depends on the infection — gonorrhea/chlamydia PCR may be valid, syphilis/HIV serology likely needs a scheduled repeat. We give a per-infection timeline, not a generic answer.
Do I need to fast before testing?
No — STI testing needs no fasting. For urine PCR, avoid urinating 1–2 hours before your visit.
Can I test without anyone knowing?
Yes — neutral paperwork, results to you only via your chosen channel. Anonymous-style arrangements are available on request.
What happens if something is positive?
Same-visit treatment planning — prescription or in-clinic injection, partner discussion, and a follow-up date before you leave.
