When should I retest for hep C?
This time is known as the window period. The hepatitis C (HCV) window period is usually 4–10 weeks from the time of exposure. After 6 months , most people will have developed enough antibodies for an HCV test to detect. In rare cases, however, antibodies can take up to 9 months to develop.
How long can hep C be active?
The Hepatitis C virus can survive outside the body at room temperature, on environmental surfaces, for up to 3 weeks However, a site quoting the CDC says “According to the U.S. Centers for Disease Control and Prevention, HCV can survive on environmental surfaces at room temperature for at least 16 hours but no longer …
What is a positive hep C result?
A positive result means that a person has the hepatitis C virus. A negative result means that the body has cleared the virus without treatment. The second test is the hep C RNA quantitative test. The result of this test is given as a number rather than a positive or negative.
How long does it take for hep C antibodies to show up?
If a person exposed to hepatitis C becomes infected, virus particles (called HCV RNA) can be detected within 1-2 weeks. Liver function tests also tend to rise during this timeframe. Hepatitis C antibodies appear after RNA is detectable and can take 3-12 weeks to appear.
How long is hep C active in dried blood?
Hepatitis B virus can live in dried blood for up to a week. Hepatitis C virus can survive for up to four days.
How long does it take to test positive for hepatitis C?

What is the difference between acute and chronic hepatitis C?
Hepatitis C can be a short-term illness, but for most people, acute infection leads to chronic infection. Chronic hepatitis C can be a lifelong infection with the hepatitis C virus if left untreated.
Which tests are used to diagnose hepatitis C virus (HCV) infection?
If recent exposure in person tested is suspected, test for HCV RNA.* A repeatedly reactive result is consistent with current HCV infection, or past HCV infection that has resolved, or biologic false positivity for HCV antibody. Test for HCV RNA to identify current infection.
What are the symptoms of hepatitis C virus infection?
Most people with chronic hepatitis C virus infection do not have any symptoms or have general, or common symptoms such as chronic fatigue and depression. Many people eventually develop chronic liver disease, which can range from mild to severe, including cirrhosis (scarring of the liver) and liver cancer.
