Hepatitis Testing in Kathmandu
- HBsAg for HBV — current-infection marker.
- Anti-HCV → RNA — two-step — active-vs-cleared.
- ~25–30% self-clear — antibody-positive but virus-gone.
- Weeks-to-months window — seroconversion timing.
Hepatitis Testing — the Serology That Matters
Hepatitis testing is serology for the B and the C ( chronic hepatitis viruses — liver-damage risk): the HBsAg for the HBV ( surface antigen — current-infection marker) and anti-HCV for the HCV ( exposure antibody — positive → the RNA for active-vs-cleared, ~25–30% self-clear).
The correct testing is two-step where it applies — anti-HCV alone does not distinguish active from cleared; the RNA is test that answers — fuller HBV panel (the HBsAg plus anti-HBs plus core) distinguishing resolved vs vaccinated vs active carrier where picture needs it.
The window honesty applies — serology detects established infection; a very recent exposure produces inconclusive until seroconversion — weeks-to-months timing is biological.
The HBV — HBsAg & the Fuller Panel
The HBsAg is current-infection marker — positive means current HBV ( active or chronic carrier state). The fuller panel (the HBsAg plus anti-HBs — immunity marker — plus core antibody) distinguishes resolved ( anti-HBs positive from resolved infection), vaccinated ( anti-HBs positive from vaccine), and active carrier (the HBsAg positive with specific pattern).
The HBsAg positive is staged for chronic-carriage picture — active vs inactive carrier distinguished by the HBeAg and viral load — management by stage ( monitoring or suppression).
HBsAg
The current-infection marker — screen.
Fuller Panel
Resolved vs vaccinated vs active carrier — where needed.
Carrier Staged
The active vs inactive — by HBeAg + viral load.
Managed by Stage
The monitoring or suppression.
The HCV — the Anti-HCV → RNA Two-Step
The anti-HCV is exposure antibody — positive means exposure at some point — the RNA then distinguishing active ( virus present — curable disease) from cleared (~25–30% self-clear — antibody positive but virus gone).
The two-step is correct sequence: anti-HCV alone does not distinguish — the RNA is test that answers whether infection is active ( curable) or resolved ( cleared).
Anti-HCV
The exposure antibody — positive means exposure.
RNA → Active/Cleared
The virus present or gone — distinction.
~25–30% Self-Clear
The resolved — antibody positive but virus-gone.
Active → Curable
The ~8–12wk DAA — ~95%+ cure.
The Window — the Seroconversion Timing
The hepatitis windows are weeks to months — serology detects established infection — a very recent exposure produces inconclusive until seroconversion ( antibodies and antigens developing).
The honest timing is assessed at consultation — for a very recent exposure retest at interval is definitive; today test establishes baseline.
Weeks-to-Months Window
The seroconversion timing — biological.
Early = Inconclusive
A too-early negative is not a clean answer.
Retest at Interval
The definitive test at correct day.
Timing Stated
Before test, not after.
After the Hepatitis Result
An HBsAg positive is staged — chronic-carriage picture assessed (the HBeAg, viral load, liver function) — management by stage ( monitoring for inactive, suppression for active).
An anti-HCV positive → the RNA → active is curable pathway (~8–12wk DAA, ~95%+ SVR12) or cleared is resolved — detection linking to management at same service.
HBV → Staged
The chronic-carriage picture — managed by stage.
HCV → RNA → Cure
The active → the ~8–12wk DAA — ~95%+.
Complete Pathway
The detection → management at same service.
HBV-Negative → Vaccinate
The ~95% vaccine where status is negative.

Frequently Asked Questions
What is hepatitis test?
HBsAg for HBV (current infection); anti-HCV ± RNA for HCV ( two-step).
Is a positive anti-HCV active?
Not necessarily — ~25–30% self-clear; the RNA determines.
Is hepatitis C curable?
Yes — ~8–12 week DAA, ~95%+ cure.
What is the HBV fuller panel?
HBsAg + anti-HBs + core — distinguishing resolved vs vaccinated vs active carrier.
When can I test?
Weeks-to-months — seroconversion timing; periodic screen for at-risk.
Is it confidential?
Yes — private testing and results.
