HAV-IgM Antibody-Serum
The HAV-IgM Antibody – Serum Test is a diagnostic blood test used to detect Immunoglobulin M (IgM) antibodies produced in response to the Hepatitis A virus (HAV). The presence of IgM antibodies indicates a recent or acute infection.
Hepatitis A is a viral infection that affects the liver and is commonly transmitted through contaminated food or water. Early detection is important to manage symptoms, prevent complications, and reduce the spread of infection.
The purpose of this test is to:
- Detect IgM antibodies against Hepatitis A virus
- Diagnose recent or acute Hepatitis A infection
- Help confirm the cause of liver-related symptoms
- Assist in timely medical management and prevention of spread
HAV-IGM ANTIBODY-SERUM Test
The HAV IgM Antibody – Serum test detects Immunoglobulin M (IgM) antibodies against the hepatitis A virus (HAV) in the blood. These antibodies typically appear early in the course of infection and are an important marker for recent or acute hepatitis A infection.
The test is commonly recommended when a person develops symptoms suggestive of hepatitis A, such as fever, tiredness, loss of appetite, nausea, vomiting, abdominal discomfort, dark urine, pale stools, or yellowing of the skin and eyes (jaundice).
A positive HAV IgM result generally supports a diagnosis of acute or recent hepatitis A infection. The result should be interpreted along with symptoms, liver function tests, and other clinical findings.
Test Recommended for Individuals:
- Individuals with symptoms suggestive of acute hepatitis A
- People with jaundice or unexplained elevation of liver enzymes
- Individuals with a known or suspected exposure to hepatitis A
- People who may have consumed contaminated food or water
- Individuals being evaluated during a suspected hepatitis A outbreak
- Patients with clinical findings suggestive of acute viral hepatitis
- Individuals advised by their healthcare provider to undergo HAV testing
