What is the meaning of HEV test?

Definitive diagnosis of hepatitis E infection is usually based on the detection of specific anti-HEV immunoglobulin M (IgM) antibodies to the virus in a person’s blood; this is usually adequate in areas where the disease is common. Rapid tests are available for field use.

What is HEV positive?

Hepatitis E is a liver disease caused by the hepatitis E virus (HEV). Although rare in developed countries, hepatitis E is widespread in the developing world. In the vast majority of people, HEV infection results in a self-limited, acute illness.

What is HAV and HEV?

Background: Hepatitis A virus (HAV) and Hepatitis E virus (HEV) are both enterically transmitted, resulting in acute viral hepatitis (AVH) in developing countries. They pose major health problems in our country.

What is HEV in histology?

Introduction. Hepatitis E is caused by a water- or food-borne, enterically transmitted infection with the hepatitis E virus (HEV), a non-enveloped, positive-strand RNA virus [1, 2]. HEV infection is one of the most common causes of acute hepatitis worldwide and thus represents a major global health problem [3, 4].

Why hepatitis E is common in pregnancy?

Immunologic changes during pregnancy promote the maintenance of the fetus in the maternal environment by suppression of T cell–mediated immunity, rendering pregnant women more susceptible to viral infections like HEV infection.

How did I get hepatitis E?

It is spread when someone unknowingly ingests the virus – even in microscopic amounts. In developing countries, people most often get hepatitis E from drinking water contaminated by feces from people who are infected with the virus.

What is HBsAg test?

The “Hepatitis B Panel” of Blood Tests HBsAg (Hepatitis B surface antigen) – A “positive” or “reactive” HBsAg test result means that the person is infected with hepatitis B. This test can detect the actual presence of the hepatitis B virus (called the “surface antigen”) in your blood.

What is HCV blood test?

A blood test, called an HCV antibody test, is used to find out if someone has ever been infected with the hepatitis C virus. The HCV antibody test, sometimes called the anti-HCV test, looks for antibodies to the hepatitis C virus in blood.

What is high endothelial?

High endothelial venules (HEV) are specialized post-capillary venous swellings characterized by plump endothelial cells as opposed to the usual thinner endothelial cells found in regular venules. HEVs enable lymphocytes circulating in the blood to directly enter a lymph node (by crossing through the HEV).
