Why This Test Matters

Hepatitis C is caused by the hepatitis C virus (HCV), which can cause liver damage over time. Different HCV genotypes (types) respond differently to treatments. This test identifies the exact genotype and subtype in your blood to guide treatment decisions.

What to Expect Before the Test

No special preparation is needed for this test. You’ll provide a blood sample, typically drawn from your arm. The sample is sent to a lab for analysis, including sequencing of viral RNA from your serum or plasma.

How the Test Works

The test uses advanced sequencing technology to analyze the genetic material of the HCV in your blood. It identifies the specific genotype (e.g., genotype 1, 2, 3) and sometimes the subtype, which helps determine the most effective treatment options.

What the Results Mean

Results show the HCV genotype and subtype detected in your sample. For example, you might see ‘Genotype 3’ or ‘Genotype 1a.’ These results help your healthcare provider choose the best antiviral medications or therapies for you.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What does my HCV genotype tell my doctor?
Your genotype helps your doctor select the most effective antiviral treatment. Some genotypes respond better to certain medications, and knowing yours ensures you get the best possible care to clear the virus and protect your liver.
How long will it take to get results?
Results are typically available within 1 to 2 weeks, depending on lab processing times. Your healthcare provider will discuss the results with you during your follow-up visit.
Can I get treated without knowing my genotype?
While some treatments can be started without knowing the exact genotype, knowing your genotype allows your doctor to choose the most targeted and effective treatment plan, improving your chances of a successful cure.
