Testing for hepatitis a--hows it done?
A doctor has provided 1 answer
Assays.: These diseases are tested by assays that test for viral antigen or antibodies. Specific diagnosis is made by the detection of hav-specific IgM antibodies in the blood, which are only present in the blood after an acute hepatitis a infection. If igg antibody is in the blood, the acute stage of the illness is past and the person is immune to further infection. The igg is also seen in vaccination.
