Hepatitis A (HAV), IgG+IgM

Description

HAV IgG & IgM Antibodies Test

This HAV IgG & IgM Antibodies Test is designed to detect the presence of Hepatitis A virus (HAV) antibodies in the blood. It helps determine past exposure, immunity status, or an active infection. This test is essential for individuals experiencing symptoms of hepatitis, those at risk due to travel or occupational exposure, and anyone needing to confirm immunity. Fast and reliable results make it easy to monitor your health from the comfort of your home or a nearby lab.

Test Purpose

The HAV IgG & IgM Antibodies Test is crucial for diagnosing Hepatitis A infections, assessing immunity, and preventing the spread of the virus. IgM antibodies indicate a recent or active infection, while IgG antibodies suggest past exposure or vaccination-induced immunity. Early detection helps in timely medical intervention, reducing complications and preventing transmission.

Symptoms That Indicate This Test

– Fatigue
– Jaundice (yellowing of the skin and eyes)
– Abdominal pain, especially in the upper right side
– Loss of appetite
– Nausea and vomiting
– Dark urine and pale stools
– Fever
– Unexplained liver enzyme abnormalities

Individuals at higher risk include those with recent travel to areas with poor sanitation, close contact with an infected person, or occupational exposure in healthcare or food service industries.

Natural Production and Regulation

The immune system produces IgM antibodies as an immediate response to HAV infection, typically appearing within two to four weeks of exposure. IgG antibodies develop later and provide long-term immunity, either from past infection or vaccination. The presence of IgG without IgM suggests immunity, while the presence of both may indicate an ongoing infection.

Risks of Untreated Conditions

Ignoring abnormal HAV antibody test results can lead to severe liver complications, including acute liver failure in rare cases. While Hepatitis A is usually self-limiting, untreated infections can cause prolonged symptoms, dehydration, and increased risk of spreading the virus to others. Individuals with pre-existing liver conditions are at higher risk of severe complications.
