Frequently Asked Questions
What does HAV-IgM indicate?
HAV-IgM is the first antibody produced during acute Hepatitis A infection and typically appears within 5-10 days of symptom onset, confirming recent or active infection.
Is fasting required for this test?
No, fasting is not required for HAV-IgM testing. Sample can be collected at any time of day.
How long does IgM remain detectable?
HAV-IgM usually persists for 3 to 6 months after infection, after which IgG antibodies become the dominant marker indicating past exposure and immunity.
Can this test distinguish between acute and past infection?
Yes, IgM positivity indicates acute or recent infection, while IgG positivity alone indicates past infection or vaccination and long-term immunity.
What sample is collected?
A 1 mL serum sample is collected from a peripheral blood draw into a plain or gel separator tube.
How quickly are results available?
Verified reports are typically available within 24 hours via www.drpatholab.in or WhatsApp/Email.
