| Hepatitis Testing : What is hepatitis testing? Hepatitis testing uses a sample of your blood to see if you have a current viral hepatitis infection or had one in the past. Hepatitis is a type of liver disease that causes liver inflammation (swelling) and damage. There are several types of hepatitis. Each affects the body and is spread in different ways. - Hepatitis A (HAV) is usually spread by eating or drinking food or beverages that an infected person has handled without washing their hands. This can result in swallowing tiny amounts of the virus that can be found in an infected person's stool (poop). You can also get HAV from close physical contact with an infected person. Though no specific medicine can cure HAV, most people recover from it on their own. The best way to prevent it is to get vaccinated. - Hepatitis B (HBV) is mainly spread through blood, semen, or other body fluids. For example, you can get an HBV infection if you have sex or share needles with an infected person. It can also be passed to your fetus during pregnancy or birth. As with HAV, no medicine can cure HBV, though most adults recover from it on their own. In some cases, it can develop into a chronic (long-term) infection. The best way to prevent HBV is also to get vaccinated. - Hepatitis C (HCV) is spread through blood. Most people get infected with HCV from sharing needles or other items used for injecting drugs, or through sexual contact. The virus can be passed to the fetus during pregnancy, but this is less common. There is no vaccine for this type of hepatitis, however, unlike with hepatitis A and B, medicine can cure it. HCV is more likely than the other types to develop into a chronic infection. - Hepatitis D (HDV) is spread the same way HBV is spread, through blood, semen, or other body fluids. However, HDV is unusual among hepatitis variants because you can only develop an HDV infection if you already have HBV. This means that those with HDV have a coinfection (getting HBV and HDV at the same time) or superinfection (having HBV and then getting HDV), which can lead to health complications. The best way to prevent HDV is to get vaccinated for HBV. - Hepatitis E (HEV) is spread by drinking contaminated water or eating undercooked foods. In most people, HEV causes an acute (sudden) infection that goes away. However, some people, especially those with weakened immune systems, may develop chronic infections. These can be treated with medicines. No vaccine is available for HEV. Most cases of hepatitis are caused by types A, B, or C. Because of this, the most common type of hepatitis test is a hepatitis panel, which checks for signs of HAV, HBV, and HCV using one blood sample. Other names: acute viral hepatitis panel, viral hepatitis screening panel, hepatitis D virus (HDV) antibody test, hepatitis B triple panel, HBsAg, anti-HBs, anti-HBc, HBV, HAV, HCV, HDV, HEV | |
