Low AST (Aspartate Aminotransferase) refers to a condition where the AST level in the blood falls below the normally accepted range of 8 to 33 U/L. This condition can be associated with various health issues such as kidney diseases, dialysis, diabetic ketoacidosis, pregnancy, B6 vitamin deficiency, and severe nutritional deficiencies. The liver performs vital functions, including the production of blood clotting proteins and the removal of toxic substances from the body. For these important liver functions to continue healthily, AST levels are expected to be within normal ranges. While low AST usually does not pose a serious problem on its own, it can sometimes be an indicator of underlying conditions like kidney diseases or diabetes. Therefore, regular monitoring of blood AST levels and medical evaluation of abnormal findings are important.
