Can a person have normal liver enzyme (e.g., ALT) results and still have Hepatitis C?
Yes. It is common for persons with chronic Hepatitis C to have a liver enzyme level that goes up and down, with periodic returns to normal or near normal. Some infected persons have liver enzyme levels that are normal for over a year even though they have chronic liver disease. If the liver enzyme level is normal, persons should have their enzyme level re-checked several times over a 6–12 month period. If the liver enzyme level remains normal, the doctor may check it less frequently, such as once a year.
Who should get tested for Hepatitis C?
Talk to your doctor about being tested for Hepatitis C if any of the following are true:
- You were born from 1945 through 1965
- You are a current or former injection drug user, even if you injected only one time or many years ago.
- You were treated for a blood clotting problem before 1987.
- You received a blood transfusion or organ transplant before July 1992.
- You are on long-term hemodialysis treatment.
- You have abnormal liver tests or liver disease.
- You work in health care or public safety and were exposed to blood through a needlestick or other sharp object injury.
- You are infected with HIV.
If you are pregnant, should you be tested for Hepatitis C?
No, getting tested for Hepatitis C is not part of routine prenatal care. However, if a pregnant woman has risk factors for Hepatitis C virus infection, she should speak with her doctor about getting tested.
What blood tests are used to test for Hepatitis C?
Several different blood tests are used to test for Hepatitis C. A doctor may order just one or a combination of these tests. Typically, a person will first get a screening test that will show whether he or she has developed antibodies to the Hepatitis C virus. (An antibody is a substance found in the blood that the body produces in response to a virus.) Having a positive antibody test means that a person was exposed to the virus at some time in his or her life. If the antibody test is positive, a doctor will most likely order a second test to confirm whether the virus is still present in the person’s bloodstream.
