Know more about this test

The Hepatitis E Virus IgG Antibody is a blood test that detects Immunoglobulin G (IgG) antibodies against past Hepatitis E virus (HEV) infection. It helps determine if an individual has been exposed to HEV in the past and whether they have developed immunity to the virus.

Understanding Hepatitis E Virus IgG Antibody

Hepatitis E is an inflammation of the liver caused by infection with the hepatitis E virus (HEV). It is transmitted mainly through contaminated drinking water. HEV causes acute liver disease, which can lead to severe outcomes, especially in high-risk populations such as pregnant women, young children and individuals with weakened immune systems.

The Hepatitis E Virus IgG Antibody test is used to detect Immunoglobulin G (IgG) antibodies, which are produced by the immune system in response to a past HEV infection. These antibodies can remain in the bloodstream for years after the infection has resolved, indicating previous exposure and immunity. This test is especially useful for understanding whether you have had HEV in the past or whether you are protected against future infection, particularly in cases where symptoms are not present but past exposure is suspected.

Hepatitis E virus (HEV) infection often presents without symptoms, but when they do occur, they can vary from mild to severe. Common signs include a mild fever, reduced appetite (anorexia), nausea, vomiting lasting several days, abdominal pain, itching, skin rash, joint pain, jaundice (yellowing of the skin), dark urine, pale stools, and a slightly enlarged, tender liver (hepatomegaly). Your doctor may recommend the Hepatitis E Virus IgG Antibody test if you experience these symptoms, or if you have a history of exposure to HEV or are at higher risk due to liver disease or pregnancy.

No special preparation is required for this test. Inform the doctor about all the medications or supplements that you are taking as these factors can influence the test results.

Lab test results may vary across laboratories. Abnormal test results require an expert interpretation, therefore, never try to self-medicate at home based solely on these results, and always consult a doctor for proper understanding of the test results and appropriate follow-up care, which may include additional testing to monitor liver function and ensure recovery.

What does Hepatitis E Virus IgG Antibody measure?

The Hepatitis E Virus IgG Antibody test measures the presence of Immunoglobulin G (IgG) antibodies specific to the Hepatitis E virus in the blood. These antibodies indicate a past infection and the development of immunity as IgG antibodies are produced as a longer-term response to a previous HEV infection. This test helps confirm previous exposure to HEV and assess immune status for those who may have been infected or are at risk of future exposure.

Frequently booked together

FAQs related to Hepatitis E Virus IgG Antibody

What is the Hepatitis E Virus IgG Antibody test?

The Hepatitis E Virus IgG Antibody test detects Immunoglobulin G (IgG) antibodies in the blood, which indicate past exposure to the Hepatitis E virus (HEV) and potential immunity against hepatitis E infection.

Why would I need the Hepatitis E Virus IgG Antibody test?

This test is used to determine if you have been previously infected with HEV and whether you have developed immunity to it. It is useful if you have symptoms that suggest past infection, have traveled to areas with HEV outbreaks, or need to assess long-term immunity.

Do I need any special preparation before the test?

No special preparation is required for this test. However, it is advisable to inform your doctor of any recent infections, or medications.

Are there any risks associated with the test?

There is usually no risk associated with this test. However, some people may feel a slight sting when a needle is pricked to collect a blood sample and may experience some bleeding that is normal and usually not bothersome.

What do the test results mean?

Positive results indicate that you have been exposed to HEV in the past and have developed IgG antibodies, suggesting past infection and potential immunity. Negative results mean that IgG antibodies are not detected, indicating no past exposure or that the infection was too recent for IgG to have developed.

How long do IgG antibodies stay in the blood?

IgG antibodies can remain detectable for years after the initial infection, providing evidence of long-term immunity.

Can this test diagnose a current Hepatitis E infection?

No, this test is not used to diagnose a current infection. For acute infections, the Hepatitis E Virus, IgM Antibody test is used to detect recent or ongoing infections.

How often should I get this test?

The frequency of testing depends on individual risk factors and exposure history. Your doctor will advise you on the need for testing based on your specific circumstances and health status.
