WHAT IS HEPATITIS A ANTIBODY (IGM AND IGG) (HAV-AB) TEST?

WHAT IS HEPATITIS A ANTIBODY (IGM AND IGG) (HAV-AB) TEST?

IgM is a marker for the hepatitis A virus that appears 2-4 weeks after exposure and is detectable for only 4-8 weeks. It does differentiate between an acute infection and past or preexisting infection. Hepatitis A is never chronic, but acute relapses occur with an overall fatality of 0.2%. IgG replaces IgM, and these antibodies persist for life, providing immunity from reinfection of hepatitis A. Hepatitis A is usually transmitted through the faecal-oral route although it can be transmitted via blood transfusion. Hepatitis A is emerging in the Middle East region, especially in ages 5-14 years.
