Seeing a positive hepatitis C result on a blood test can understandably be frightening. You may immediately worry about liver damage, long-term health problems, or whether hepatitis C can be treated. The important thing to know is that a positive screening result does not always mean that you currently have an active hepatitis C infection.
Further testing can clarify what the result means, whether the virus is currently present, and whether your liver needs additional assessment. With modern treatment, hepatitis C can often be cured.
The first test commonly used to screen for hepatitis C is the hepatitis C antibody (anti-HCV) test. A positive result means that your immune system has been exposed to the hepatitis C virus at some point.
However, antibodies can remain in the blood even after the body has cleared the virus. Therefore, an antibody-positive result alone cannot confirm an active infection.
The next important test is usually an HCV RNA test, also called a hepatitis C viral load test.
This blood test looks directly for the genetic material of the hepatitis C virus:
This distinction is important because a positive hepatitis C antibody test does not automatically mean that you have chronic hepatitis C.
If active hepatitis C is confirmed, your doctor may recommend additional blood tests to understand your overall health and liver function.
Tests such as ALT, AST, GGT, ALP and bilirubin can provide information about liver inflammation or changes in liver function.
It is important to remember that normal liver enzymes do not completely rule out chronic hepatitis C or liver damage.
A complete blood count can provide information about your blood cells and may offer additional clues about your general health and liver condition.
Kidney function may also be checked, particularly when treatment decisions are being considered.
Hepatitis C has different genetic types, known as genotypes. Depending on the treatment approach available and your clinical situation, your doctor may recommend genotype testing.
Modern hepatitis C treatments are highly effective across many types of the virus, so genotype testing is not necessarily required in every situation.
Finding out whether hepatitis C has affected the liver is an important part of the assessment. Your doctor may use blood tests and non-invasive methods to estimate the amount of liver fibrosis, or scarring.
Depending on your individual circumstances, this may include:
A liver biopsy is not routinely required for every person with hepatitis C. Your specialist will determine whether it is necessary based on the available information.
Long-term hepatitis C infection can cause inflammation and progressive scarring of the liver. Advanced fibrosis can eventually lead to cirrhosis.
Knowing whether fibrosis is present helps your healthcare team understand your current liver health and determine the appropriate follow-up after treatment.
Your doctor may recommend testing for other viral infections, particularly hepatitis B and HIV, depending on your medical history and risk factors.
These tests can be important because co-existing infections may affect your overall care and treatment plan.
Yes. This is one of the most reassuring developments in hepatitis C care. Modern antiviral medicines can eliminate the virus in most people when taken as prescribed.
Treatment choice and duration depend on factors such as the type of hepatitis C infection, previous treatment, liver condition, and other health considerations.
After treatment, an HCV RNA test is generally used to confirm whether the virus has been successfully cleared.
If your hepatitis C screening test is positive, try not to panic. A sensible next step is to:
