Hepatitis A is a viral infection that primarily affects the liver. It is typically spread through the consumption of contaminated food or water or through close contact with an infected person. Hepatitis A does not result in chronic infection, and most individuals recover completely with proper medical care.
Screening for Hepatitis A is usually done through blood tests. Here are the common tests used for Hepatitis A screening:
Hepatitis A Antibody Tests:
IgM Antibody Test:
This test detects the presence of IgM antibodies specific to the Hepatitis A virus. IgM antibodies are produced in the early stages of infection and indicate an acute or recent infection. A positive IgM result suggests recent exposure to the virus.
IgG Antibody Test:
This test measures the levels of IgG antibodies against Hepatitis A. IgG antibodies are produced later in the infection and remain in the body for a longer time. A positive IgG result may indicate a past infection or vaccination.
Sample Requirement
Blood Sample Type:
Venous Blood: A venous blood sample is most commonly used for Hepatitis A Screening. It is drawn from a vein, usually in the arm, using a needle and a collection tube.
