What is the lever function test?

Liver function tests are blood tests that measure different substances produced by your liver. These measurements can help your doctor evaluate the overall health of your liver and how well it's working. A liver panel will often measure several substances in one blood sample.

Does cirrhosis always appear on blood tests (ALT/AST)?

No not always. However, one can rely on the AST/ALT ratio. An AST/ALT ratio higher than one (where the AST is higher than ALT) means you may have cirrhosis. An AST/ALT ratio higher than 2:1 (where the AST is more than twice as high as the ALT) is a sign of alcoholic liver disease.

What happens when the PT is high in viral hepatitis?

When the PT is high, it takes longer for the blood to clot (17 seconds, for example). This usually happens because the liver is not making the right amount of blood clotting proteins, so the clotting process takes longer. A high PT usually means that there is serious liver damage or cirrhosis.
