Do they test for hepatitis a when donating blood?

Yes, hepatitis A is one of the infectious diseases that are routinely tested for when donating blood. Blood donation centers and transfusion services use various screening methods, including serological tests, to detect the presence of hepatitis A virus (HAV) or antibodies against HAV in donated blood. These tests help ensure the safety of the blood supply by identifying potential infections and preventing the transmission of HAV through blood transfusions.
