Elevated LFTs

LFTs

LFTs (liver function tests) are blood tests that check the functioning of the liver by measuring levels of proteins, enzymes, and waste products in the blood. One or more of the LFT’s parameters can be abnormal due to inflammation or damage to cells in the liver. Elevated LFTs indicate liver abnormalities.

We will teach you how to understand your results for some of the common liver function tests including alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), bilirubin and L-lactate dehydrogenase (LDH).

How bad is my elevated LFTs?

You should be concerned about the LFTs readings that fall out of the normal range. Your doctor will use these results to help diagnose your condition or determine the treatment you might need.
