ACG Guideline on Evaluation of Abnormal Liver Chemistries Recommends “New Normal” for Serum ALT Levels

A new clinical guideline from the American College of Gastroenterology offers the first recommendations in over 10 years on the evaluation of abnormal liver chemistries. For the first time in a liver test guideline, the authors define a normal healthy serum alanine aminotransferase (ALT) level for women and men (up to 25 IU/L for women, up to 33 IU/L for men) and recommend that levels above this should be assessed by physicians.
