Testing Reality in Kathmandu
- Carrier infections dominate the positives — most of our positive results come from screening, not symptoms.
- Method substitution is common — antigen kits and antibody-only tests where PCR is needed.
- Site-matched sampling is rare — throat and rectal infections invisible to urine tests go undetected.
- Window honesty is uncommon — early negatives handed over as final answers.
Testing for Infections, Not Just Diseases
Testing for disease is reactive — something felt wrong. Testing for infection is proactive — the point is finding what is present before it produces anything. That is the defining feature of a proper STI testing service: the methods and schedules are built around asymptomatic detection, because most of the infections that matter spend most of their course silent.
Accuracy for carrier detection has specific requirements: nucleic acid testing (NAAT/PCR) that finds low-load bacterial infection, antibody-and-antigen serology that catches infection before symptoms, and honest window-period practice — a negative inside the window is scheduled for confirmation, not filed as an all-clear.
This page covers the infections worth testing for, the methods per infection, the window periods, and how the whole thing stays private.
What a Complete STI Test Covers
Bacterial — PCR
Chlamydia, gonorrhea, trichomonas, mycoplasma/ureaplasma — NAAT on urine or site swabs.
Syphilis — paired serology
RPR/VDRL titer + treponemal confirmation, always together.
HIV — 4th gen + RNA option
Ag/Ab conclusive at 45 days; RNA PCR for ~10–33-day detection.
Hepatitis B & C — serology
HBsAg and anti-HCV blood tests.
Clinical diagnoses
Warts, herpes, molluscum — examination-based, plus PCR where lesion confirmation helps.
Comprehensive panel
STI-29 PCR — maximal single-visit coverage.
Why Test Without Symptoms
- Chlamydia: ~70–80% of female, ~50% of male infections silent — and fertility-relevant.
- Gonorrhea: pharyngeal and rectal infections characteristically asymptomatic.
- Syphilis: latent phase — years silent, progressively damaging.
- HIV: asymptomatic for years while transmissible.
- Hepatitis B: occult carriage, liver damage without symptoms.
- The carrier state is the STI's natural state — testing is how it is found.
Window Periods Per Infection
- Gonorrhea/chlamydia PCR: ~1–2 weeks.
- Syphilis serology: ~3–6 weeks.
- HIV 4th gen: 18–45 days (conclusive at 45); RNA ~10–33 days.
- Hepatitis B/C serology: ~4–10 weeks.
- Inside-window negatives get scheduled confirmation — that is the honest practice.
How Testing Works
- Brief risk history → matched tests and sites.
- One sampling session — urine/self-swab/site swabs + one blood draw.
- Results 24–48 hours — delivered to you alone.
- Doctor interpretation — what each result means for you.
- Positive → same-visit treatment plan. Negative → your next date.
Testing Options & Indicative Costs
| Service | What It Includes | Cost (NPR) |
|---|---|---|
| Consultation + selection | Right tests for your exposure. | Rs. 450 |
| PCR infections | Per-pathogen or dual NAAT. | Rs. 6,000 – 12,000 |
| Serology set | Syphilis + HIV + hepatitis combined. | Rs. 4,000 – 8,000 |
| STI-29 panel | Comprehensive PCR coverage. | Package — call |
| Multi-site swabs | Rectal/pharyngeal where indicated. | Per-site rates |
Panels reduce per-infection cost — call for rates.
Why We're the Best for STI Testing
- Carrier-detection methods — PCR and proper serology, not weak rapid kits.
- All sites — the throat and rectal swabs most centers skip.
- Window honesty — early negatives scheduled for confirmation.
- Interpretation included — a doctor explains every result.
- Private end to end — neutral process, sealed results.
- Same-visit conversion — positives become treatment plans immediately.
Frequently Asked Questions
Which infections can be tested without symptoms?
All the major ones — chlamydia, gonorrhea, syphilis, HIV, hepatitis B/C, trichomonas and more. Asymptomatic detection is precisely what these tests are designed for.
How accurate is testing without symptoms?
PCR and 4th-gen serology are highly accurate regardless of symptoms — accuracy depends on method and window period, not on whether you feel anything.
What samples are needed?
Urine or self-collected swabs for most; blood draw for serology; site swabs (rectal/throat) where exposure indicates. No internal exam needed for asymptomatic testing.
How private is the process?
Completely — neutral visit appearance, results to you alone, optional minimal-identification arrangements.
What if I test too early after exposure?
We tell you honestly and schedule the conclusive date — an early negative is provisional information, not a verdict.
