Which liver function test indicates viral hepatitis?

Hepatitis Panels. Liver function tests are not really used to diagnose viral hepatitis, but elevated ast, alt, ggt, alkaline phos, bili can indicate "something" is wrong and needs evaluation::. Hepatitis panels for anti-bodies, core anti-bodies, and antigens for each of the different types of hepatitis (a, b, c, etc.) are used to indicate whether viral hepatitis is present and the severity/length of the infection.
No specific one. Liver function tests, which usually are composed of bilirubin, ast, alt and alkaline phosphatase, are non-specific indicators of liver health. These can be elevated in a variety of diseases, some of which are viral hepatitis, but can also be affected by other noxious processes. Only tests that measure the virus or response to the virus specifically can tell if you have or had viral hepatitis.

Thx dr. Fung, I have already done the hep a, b, c tests, all negative 1, 5 yrs after exposure, in this case of fatty liver can I rule out viral hepatitis?

Most likely. Assuming that you have no further risk exposure and tested negative, then that is not likely to be the reason for elevated liver function tests. Fatty liver is a possibility, but there are other causes for liver disease that you should be evaluated for, possibly requiring a liver biopsy for confirmation. Also depends on the pattern of liver function abnormality. Continue to abstain from alcohol. Read more...

I was diagnosed with hepatitis B, I went for liver function test that reveal high alkaline phosphate (44) what does it mean and do I do?

Discuss w/ provider. Although you give 44 - you don't name the units but if this is high, it's about your liver being damaged. What you need to do is talk to the provider who tested you about the results and a treatment plan. Then you have to decide to try your best to follow the plan. It is an STD and serious so ALWAYS use condoms to not spread it. It is like assaulting your partner if you don't. Please care! Read more...
Alkaline phosphatase. This enzyme, when produced by the liver (may be from other sources), emanates from biliary radicals that are inflamed or obstructed. Depending upon other factors you may need further imaging, perhaps a liver biopsy and treatment with antiviral drugs now effective against HepB virus. See an expert in this area and follow their recommendations. Best wishes. Read more...
