Hepatitis A: HAV IgM (HAV IgM)

What Is Hepatitis A?

Hepatitis A is a contagious viral infection that primarily targets the liver. It is commonly transmitted through ingestion of contaminated food or water. This liver infection is especially prevalent in areas with poor sanitation and limited access to clean water, making awareness and prevention vital.

Immune Response and Antibody Production

Following exposure to the hepatitis A virus (HAV), the immune system responds by producing specific antibodies to fight the infection. These antibodies can be identified in the blood through a specialised HAV antibody (HAV Ab) test, which plays a crucial role in both diagnosis and immunity assessment.

Understanding HAV Antibody Test Results

The HAV antibody test detects two types of antibodies in the bloodstream—IgM and IgG:

IgM Antibodies: Their presence typically suggests a recent or ongoing infection. A positive IgM result may indicate that the individual is in the early stages of hepatitis A and may still be infectious.

IgG Antibodies: These antibodies signal that the individual has either recovered from a past hepatitis A infection or has been vaccinated. IgG antibodies offer long-term immunity against the virus.
