Hepatitis
Point-of-care rapid testing for hepatitis. OEM/ODM manufacturer.
Overview
Viral hepatitis (A/B/C/E) is a major global burden. HBsAg and anti-HCV are the core screening markers; HAV/HEV IgM indicate acute infection.
Diagnostic Markers & Methods
HBsAg (surface antigen) · anti-HCV (antibody) · HAV IgM · HEV IgG/IgM · combo cassettes.
Testing Window
HBsAg: earliest HBV marker. Anti-HCV: ~4–10 weeks after exposure.
Interpretation
HBsAg positive = HBV infection (acute or chronic). Anti-HCV positive = exposure, NOT active infection — confirm with HCV RNA.
Confirmatory Testing
Anti-HCV reactive → HCV RNA. HBsAg reactive → HBV DNA/panel.
The Author's Take
Position: When sourcing hepatitis tests, separate screening from confirmation — anti-HCV is a screen, not a diagnosis, and your buyers must understand that.
- HBsAg detects active or chronic HBV; anti-HCV only indicates exposure — reflex to HCV RNA is required.
- Blood-bank and antenatal programs run HBsAg/HCV/HIV/syphilis combos for throughput.
- Selling a clear 'screen vs confirm' story protects you and your buyers from misuse.

Frequently Asked Questions
Does a positive HCV antibody test mean active infection?
No — anti-HCV indicates exposure (current or past). Active infection requires confirmation with HCV RNA.
What is the earliest marker of hepatitis B?
HBsAg is the earliest serological marker of acute HBV and a marker of chronic infection.
Can rapid tests distinguish acute from chronic hepatitis B?
No — HBsAg positivity alone cannot distinguish acute from chronic; this requires additional markers (IgM anti-HBc) and clinical context.
