Why are patients advised to avoid alcohol 48 hours before a liver function blood test?

Could it cause results on the test to say liver inflammation if you had been drinking a lot of alcohol 48 hours before that type of test?

    Yes, it can cause incorrect results. But it doesn't measure inflammation. Liver function tests measure specific enzymes and products of the liver like AST, ALT and a host of other variables. And alcohol beforehand can affect the numbers.
