Q2: Can this test distinguish between current and past infections?
A: No, IgG antibodies indicate past exposure or immunity but don’t differentiate between recent or previous infections.
Q3: Does vaccination for Hepatitis A produce IgG antibodies?
A: Yes, vaccination stimulates the production of IgG antibodies, providing immunity similar to natural infection.
Q4: Can false-positive results occur with this test?
A: Rarely, cross-reactivity with other viral infections or issues with the testing process might lead to false-positive results.
