HAV IgM(Hepatitis A Antibody) TEST

HAV IgM test for antibodies in your blood. The test can find out if you are infected with the hepatitis A virus (HAV). Hepatitis is an inflammation of your liver, often caused by an infection. Most hepatitis infections are caused by 1 of 5 viruses: hepatitis A, B, C, D, or E. Because the symptoms of all of these infections are similar, this blood test can tell your healthcare provider which type of virus you may have. Your immune system makes antibodies when you are first infected with HAV. It can take 14 to 50 days to develop symptoms of hepatitis A after you become infected. The average time to get symptoms after you are infected is 30 days. Antibodies often begin to appear in your blood 5 to 10 days before you start having symptoms. They can stay in your blood for about 6 months after the infection. Some antibodies called IgG can last in your blood for life.
