Elevated ALT levels
 

Ok, so a couple of time, not all the time, but a couple of times when I've donated blood, I've gotten a message back that I've got an elevated ALT level.

How serious is this?

I'm actually about to go on an alcohol fast for a month to do another blood test with my doctor, to do some tests on my triglycerides, and I'm going to have them check this out at the same time.

But should I be worried?

Maybe, but you won't know for sure until other liver function tests are completed. AST/ALT ratio is an important one, so ALT alone give partial info although it does insinuate that something could be wrong.

cut the etoh and then check. Alcohol has a way of screwing up your liver.

Good ideas get a before and after with the exclusion of ethanol
ALT = amino alanine transferase and is usually elevated with liver cell injury and/or infectious hepatitis. Ethanol can obviously cause liver cell damage but other LFT's like;
SGGT and AST and full blood's will make the results clearer
