Several types of blood or body fluid tests are available to test for hepatitis A, B, and C. A doctor might order one or a combination of tests. In general, the tests determine if antibodies (body's natural reaction against infection) are present in the blood. There are other tests that might find the actual hepatitis viruses.
If any type of hepatitis is diagnosed, a doctor should also test for liver disease. This is done to determine if the hepatitis virus has caused any or major damage on your liver.
Drinking alcohol should also be avoided if hepatitis is diagnosed. Alcohol increases the effect of liver damage, making it worse.
If you think you might have or have been exposed to any type of hepatitis talk to your doctor, nurse, clinic, or local health department.
