Hi...

HCV RNA appears in blood and can be detected as early as 2–3 weeks after infection.

There are many different blood tests available to diagnose Hepatitis B. They can be ordered as an individual test or as a series of tests. Ask your health professional to explain what he or she hopes to learn from the tests and when you will get the results. Below are some of the common tests and their meanings.
