用速率法测定尿NAG活性及其临床应用

Kinetic Analysis For Urinary NAG Activity and Clinical Application

本文报道用５５０型全自动生化分析仪，以速率法测定尿ＮＡＧ活性及本室尿ＮＡＧ活性的正常参考范围（３．６～２１．１Ｕ／ｇ·ｃｒ，－ｘ±ｌ．９６ｓ）；并对可能影响尿ＮＡＧ活性的尿ｐＨ，尿素浓度等进行了干扰试验及分析．

inetic method was used to assess the activity of human urinary NAG with CIBA一corn-ing automatic analyzer,and normal reference range(3.6～21.1U/g.cr).Interference fac-tors in urinary NAG measure were studied.
