How Do You Find Out if You Have Hepatitis C?

People learn if they have hepatitis C by taking a blood test. But it’s important to remember that routine blood tests taken during a regular physical exam don't usually test for hepatitis C.

Why do some people learn they have hepatitis C when they donate blood or have a blood test?

If the antibody test is positive, it means that you have been exposed to the virus. But your body may have already removed the virus on its own; some people (25%) can get rid of the virus on their own. Another test is needed to confirm that the actual virus is still in your body

  • Some people can get rid of the virus on their own without treatment. But the antibodies used to fight the virus will still show up in the antibody test. If you test positive for hepatitis C antibodies, other tests may be used to determine that the virus itself is in your blood. One of these tests is called a polymerase chain reaction test, or PCR. A PCR test tells the doctor if there is any virus in the blood and how much
