Why This Test Is Done
Your healthcare provider may order this test if you have symptoms of Hepatitis C (such as fatigue, abdominal pain, or jaundice) or if you’ve been exposed to the virus. It’s also used to confirm infection after initial screening and to determine the best treatment plan.
How the Test Works
A small blood sample is taken and analyzed using a specialized probe that targets the genetic material of Hepatitis C. This method detects the virus’s presence and identifies which genotype you have, which can vary from 1 to 6.
What to Expect Before the Test
No special preparation is needed. You may have a slight pinch when the blood is drawn, but it usually takes only a few minutes. If you’re pregnant, have a bleeding disorder, or are on blood-thinning medication, let your provider know.
What the Results Mean
A positive result means you have Hepatitis C, and the genotype number indicates which strain you have. This information helps your doctor choose the most effective treatment, such as antiviral medications, tailored to your specific genotype.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Hepatitis C genotypes differ in how they respond to treatment and may require different durations or combinations of medications. Accurate genotyping ensures your treatment is as effective as possible and helps prevent long-term liver damage.
