Hepatitis C Tests

You can be infected with the hepatitis C virus and have no symptoms. Your doctor could find it when he checks your blood and sees that your level of certain liver enzymes is high. If that happens, he'll follow up with other tests to confirm you have the disease.

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 that you received blood or an organ transplant from a donor who later tested positive for the disease
  • You have ever injected drugs, even once many years ago
  • You received a blood transfusion or an organ transplant before July 1992
  • You received a blood product used to treat clotting problems that was made before 1987
  • You were born between 1945 and 1965
  • You have had long-term kidney dialysis
  • You have signs or symptoms of liver disease
  • You have HIV
  • You have a known exposure to HCV
  • You have persistent elevations of a liver blood test called ALT (alanine aminotransferase levels)

Other people for whom hepatitis C virus testing is indicated include:

  • Children born to HCV-positive mothers
  • Hospital and other health care facility workers after a needle stick or exposure to the blood of a person with HCV
  • Public safety and emergency medical workers after a needle stick or exposure to the blood of a person with HCV

The following people who are at increased risk for contracting hepatitis B virus include:

  • People who received a blood or a blood-product transfusion prior to 1972
  • Hospital and health care workers
  • Household members of an infected person
  • Intravenous drugs users (both present and former users)
  • People who have had a tattoo or a body part pierced with an infected needle
  • Sex partners of infected people
  • Travelers to countries where HBV is endemic
  • People who were born to a mother infected with HBV
  • Transplant-organ recipients who received an infected organ

The following groups of people should be screened for hepatitis B virus:

  • People born in areas where HBV is endemic
  • Men who have sex with men
  • Intravenous drug users (both present and former users)
  • Dialysis patients
  • HIV-infected people
  • Pregnant women
  • Family members, household members, and sex partners of HBV-infected people (even if sex occurred on only one occasion)
  • People who have had more than one sex partner within 6 months

Otherwise, routine screening for hepatitis typically is not recommended unless you have symptoms or signs (such as abnormal liver-related blood tests) of the condition.
