【答】谷丙转氨酶是肝脏中一种重要的酶,为目前酶学诊断中最常用的方法之一。引起谷丙转氨酶升高的原因很多,肝脏病变中以病毒性肝炎最为常见,其他如心、肾、脑、肠等病变,药物的影响,胆道梗阻等,均可使谷丙转氨酶升高。因此,在诊断上首先应注意鉴别一切可能引起谷丙转氨酶升高 [A] Alanine aminotransferase is an important enzyme in the liver, is currently one of the most commonly used method of enzymology diagnosis. Lead to elevated alanine aminotransferase many reasons, the most common viral hepatitis in liver disease, other diseases such as heart, kidney, brain, intestine, the impact of drugs, biliary obstruction, etc., can make alanine aminotransferase increased. Therefore, the diagnosis should first pay attention to identify all may lead to elevated alanine aminotransferase
