Hepatitis A: HAV IgM (HAV IgM)

Hepatitis A is a viral infection that affects the liver, and is typically spread through contaminated food or water. The body's immune system produces antibodies to fight off the virus, and these antibodies can be detected in the blood through a test for HAV Ab. If HAV antibodies are detected in an individual's blood, it indicates that they have been exposed to the virus at some point in the past. If IgM antibodies are present, it may indicate a current or recent infection, while the presence of IgG antibodies indicates past infection or vaccination.
