title: Isolated elevated aspartate aminotransferase: a surprising outcome for clinicians.
abstract: In this report a case of macro-aspartate aminotransferase in a 34-year-old pregnant woman is presented. Awareness of the existence of a macroenzyme is important because of their ability to cause diagnostic confusion, which leads to unnecessary investigations. Confirmation with a polyethylene glycol precipitation test is simple to perform and not expensive.
