How soon can hepatitis be detected?
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.
Do you really have to fast for 12 hours before a blood test?
How long should you fast before a blood test? The amount of time you need to fast for will vary depending on the test. For most tests, you will be told not to consume anything but water for eight hours leading up to the test. For a few tests, a 12-hour fast may be needed.

In acute infection, HBsAg usually disappears within 1 to 2 months after onset of symptoms. HBsAg persists in patients with chronic hepatitis.
How do you confirm hepatitis?
Blood Tests Your doctor draws a small amount of blood from a vein in your arm and sends it to a laboratory for testing. The results of a blood test can confirm the type of viral hepatitis, the severity of the infection, whether an infection is active or dormant, and whether a person is currently contagious.

What is the best treatment for hepatitis B?
Antiviral medications. Several antiviral medications — including entecavir (Baraclude), tenofovir (Viread), lamivudine (Epivir), adefovir (Hepsera) and telbivudine (Tyzeka) — can help fight the virus and slow its ability to damage your liver.

How long can Hepatitis B patient live?
The estimated carrier life expectancy is 71.8 years, as compared to 76.2 years among noncarriers (Figure 5). These results are consistent with other estimates, which indicate that 15% to 40% of HBV carriers die of liver complications.
Which Hepatitis is not contagious?
Some infectious parasites (such as Plasmodium spp, Schistosoma spp) cause hepatitis in individuals, but are not contagious person to person. Most noninfectious causes of hepatitis are not contagious. Hepatitis caused by alcohol poisoning, medications, or toxins or poisons are not transmitted from person to person.
