乳酸脱氢酶(LDH)测定,对心肌梗塞及某些肿瘤病例的辅助诊断具有一定价值。目前国内临床实验室多采用比色法,操作虽然简便,但因基质液容易变质,在冰箱保存2周后,空白A值即明显上升,而酶促反应的敏感性都相应下降,不但影响实验质量,同时还经常造成试剂和人力的浪费,使基层临床实验室 Determination of lactate dehydrogenase (LDH), the diagnosis of myocardial infarction and some tumor cases have some value. At present, more clinical laboratories using colorimetric method, although the operation is simple, but the matrix liquid perishable, stored in the refrigerator for 2 weeks, the blank A value that is significantly increased, while the sensitivity of enzymatic reactions were reduced, not only affect the experiment The quality, at the same time, also often results in wasted reagents and manpower, making primary clinical laboratories
