Viral hepatitis, such as hepatitis C (HCV), hepatitis B (HBV) and hepatitis A (HAV), is diagnosed by your symptoms, a physical exam, blood tests, and other studies, such as FibroSure. Sometimes imaging studies such as a sonogram or CAT scan and a liver biopsy are also used.
Hepatitis: Who's at Risk?
For hepatitis C, the CDC recommends that you have a blood test if any of the following is true:
You have received an organ transplant or transfusion in the past.
You have been notified...
Hepatitis B. Most people recover from this type in 6 months. Sometimes, though, it causes a long-term infection that could lead to liver damage. Once you've got the disease, you can spread the virus even if you don't feel sick. You won't catch it if you get a vaccine.
Hepatitis C. Many people with this type don't have any symptoms. About 80% of those with the disease get a long-term infection. It can sometimes lead to cirrhosis, a scarring of the liver. There's no vaccine to prevent it.
How Do You Get Hepatitis A?
You get it from eating or drinking something that's got the virus in it.
