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

Question

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?

Answer 1

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.
