CX_4全自动生化分析仪测定血清中的N-乙酰-β-D氨基葡萄苷酶

使用CX_4全自动生化分析仪和手工法同时测定48份不同血清中的NAG活性值,二者的相关系数r=0.86,具有统计学意义(P<0.01),并且前者的测定,较后者更为缩短了时间,扩大了检测的线性范围(<1000IU/L),适宜大规模测定,使血清NAG测定成为实验室的常规检测项目之一,同时,通过测定60例门诊健康体检者的血清NAG活性值,得出正常参考值范围13.98±5.52IU/L,检测40例不同疾病的临床患者血清NAE活性值,发现与正常对照组有明显差异(P<0.05),认为血清NAG活性的测定对临床有一定的诊断意义。

N- Acetyle - β - D - Glucosaminidase in Serum Determined With CX_4 Fully Automatic Biochemistry Analyzer

CX4 fully automatic biochemistry analyzer and manual methods are used to determine NAG active value in 48 kinds of different serum. Their reldated coefficients are r=0.86 with statistical meaning (p<0.01). The determination of the former needs shorter time thanthe latter, extending testing linear range (<1000IV/L), being suitable for large -scale determination. Therefore, determination of NAG in serum has become one of the routine testing items. Meanwhile, by determining NAG active value in serum of 60healthful outpatients, the range of normal reference value is 13.98±5.52 IU/L . By testing NAG active value in serum of 40 clinical patients with different diseases, we have found there is an obvious difference from the normal contrasting group and believed that determination of NAG active value in serum has a certain meaning of clinical diagnosis.
