Frequently Asked Questions
What does HEV IgM indicate?
HEV IgM antibodies appear early during acute Hepatitis E infection, typically within days of symptom onset, and indicate recent or active infection.
Is fasting required for this test?
No, fasting is not required for HEV IgM testing. Sample can be collected at any time of day.
How long does IgM stay positive?
HEV IgM usually remains detectable for 3 to 6 months after infection, then declines as the body clears the virus.
Can this test distinguish between past and current infection?
Yes, IgM indicates recent or active infection while IgG indicates past exposure or immunity. Both are often tested together for accurate interpretation.
What are the symptoms of Hepatitis E?
Common symptoms include fever, jaundice, dark urine, nausea, abdominal pain, and fatigue. Many infections are mild and self-limiting.
How is Hepatitis E transmitted?
Hepatitis E is primarily spread through contaminated water and food, especially in areas with poor sanitation. It can also rarely transmit through blood or from mother to fetus.
