Anti Hepatitis A (IgM)

The Anti-Hepatitis A IgM (Anti-HAV IgM) Test is a blood test used to detect IgM antibodies against the Hepatitis A Virus (HAV).

This test helps healthcare professionals diagnose a recent or acute Hepatitis A infection. Hepatitis A is a viral infection that primarily affects the liver and is commonly transmitted through contaminated food, water, or close contact with an infected person.

What Does This Test Check?

• Detects IgM antibodies against the Hepatitis A Virus (HAV).

• Helps diagnose recent or acute Hepatitis A infection.

• Supports the investigation of symptoms such as jaundice, fatigue, nausea, abdominal discomfort, and dark urine.

• May assist in evaluating patients with abnormal liver function tests.

• Helps healthcare professionals investigate suspected Hepatitis A exposure when clinically appropriate.

Sample Requirements

• Sample Type: Clotted Blood or Serum

• Required Quantity: 2–3 ml

• Department: Serology / Immunology (subject to laboratory confirmation).

Patient Preparation

• Fasting is generally not required for the Anti-Hepatitis A IgM Test.

• Inform your healthcare provider if you have recently experienced symptoms of hepatitis or jaundice.

• Inform your doctor about any recent exposure to contaminated food or water or contact with someone diagnosed with Hepatitis A.

• Inform your healthcare provider if you have recently received a Hepatitis A vaccination.

• Follow any specific sample collection instructions provided by the laboratory.

Important Information

The Anti-Hepatitis A IgM Test detects antibodies associated with recent or acute Hepatitis A infection.

A positive or reactive Anti-HAV IgM result may indicate a recent or current Hepatitis A infection. However, false-positive results can occur, and IgM antibodies may sometimes be detectable after recent vaccination or persist following infection.

A negative or non-reactive result indicates that Hepatitis A IgM antibodies were not detected. However, testing very early in the infection may produce a negative result before sufficient antibodies have developed.

For assessing immunity due to previous Hepatitis A infection or vaccination, the Anti-HAV IgG Test or total anti-HAV antibody test may be used.

Results should be interpreted by a healthcare professional alongside symptoms, exposure history, liver function tests, and other relevant investigations.

Reporting Time: To be confirmed by the laboratory.
