ACG Guideline on Evaluation of Abnormal Liver Chemistries Recommends “New Normal” for Serum ALT Levels
American College of Gastroenterology (ACG)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.
