Hepatitis A Virus - IgG Test

Hepatitis A is a virus that affects the functioning of the liver. This virus enters the body due to the intake of contaminated food and water or contact with an infected person. The after-effects of the hepatitis A virus range from mild fever to severe consequences such as nausea, indigestion, dizziness, and extreme fatigue. There are two kinds of antibodies that lead to the hepatitis infection: IgM and IgG. The Hepatitis A Virus IgG test detects the presence of the IgG antibodies in the blood and informs of the possible health problems.

There are no special preparations required for doing this test. You can consult your doctor regarding the medications you take daily. He/she will suggest you avoid any medicines which can cause interference with the results. This is a routine blood test and you need to dress suitably for that. Wear a half-sleeved shirt or something which doesn’t interfere with the test.

This test has a number of uses. The most important use of the HAV IgG test is that it locates the extent of the Hepatitis A virus in the blood and informs of the type of antibodies. It determines the major cause of Hepatitis A virus. It is also used to analyse whether an individual who has already suffered from the disease has the right immunity to it for the future or not. It helps in deciding the need for HAV vaccination. It is performed with a few other tests such as ALT and AST to make further analysis.

The blood test is carried out through the following steps: Wrap an elastic band to your upper arm for stopping the blood flow. Clean the site for needle insertion with an alcohol pad. Put the needle into the vein and draw out the blood sample. Clean the site and bandage it. The sample is tested in the laboratory for determining the Hepatitis A virus in the blood.
