Hepatitis A: HAV Antibodies Total (HAV Ab)

What Is HAV Ab (Hepatitis A Virus Antibodies)?

HAV Ab refers to antibodies produced by the immune system in response to the hepatitis A virus (HAV), a contagious liver infection typically spread through contaminated food or water. These antibodies are key indicators of current or past infection and can be identified through a simple blood test.

How Hepatitis A Spreads

Hepatitis A is commonly contracted via the consumption of food or water contaminated with the virus. Poor hygiene and inadequate sanitation increase the risk of transmission, especially in areas with limited access to clean water sources.

Types of Hepatitis A Antibodies

Two types of hepatitis A antibodies can be detected in the blood:

IgM Antibodies: These are the first antibodies to appear in response to an acute HAV infection. They are usually detectable during the early stages of illness and tend to disappear within a few months.

IgG Antibodies: These antibodies develop later and remain in the body for life, providing long-term immunity. Their presence indicates a previous infection or successful vaccination.

Purpose of HAV Ab Testing

HAV Ab testing is commonly used to:

Confirm a current or recent hepatitis A infection

Determine if a person has previously been exposed to HAV

Check immunity following vaccination

Screen individuals at high risk of infection, such as healthcare professionals or travellers to high-risk regions
