摘要
目的:建立半自动生化分析仪检测精浆α葡糖苷酶活性的方法。方法:同时用半自动生化分析仪法(速率法)和手工葡萄糖氧化酶法检测51例精液常规分析参数均正常的男性精浆α葡糖苷酶活性,计算批内和批间变异系数以及正常参考值范围,并分析两种方法检测结果的相关性。结果:2例α葡糖苷酶活性不同的精浆样本用半自动生化分析仪法检测的批内变异系数分别为12.63%和9.13%,批间变异系数分别为10.67%和13.49%,正常参考值范围为102.28~555.08U/L。半自动生化分析仪法和手工法检测的精浆α葡糖苷酶活性呈显著正相关(r=0.792,P<0.01)。结论:半自动生化分析仪检测精浆α葡糖苷酶活性法简便、省时,节省试剂,结果稳定可靠。建议在男科实验室推广使用半自动生化分析仪法检测精浆α葡糖苷酶活性。
Objective: To establish a method of determining alpha-glucosidase activity in seminal plasma by semi-automatic biochemistry analyzer. Methods: Alpha-glucosidase activity in seminal plasma from 51 men with normal semen parameters in routine semen analysis were detected by semi-automatic biochemistry analyzer and manual glucose oxidase method, respectively. Then, the intra-assay and inter-assay coefficient variation (CV) and normal reference value were calculated. In the meanwhile, the correlation between the two methods was analyzed. Results: The intra-assay CVs of 2 seminal plasma samples with different alpha-glucosidase activity detected by semi-automatic biochemistry analyzer were 12.63% and 9.13% , and the inter-assay CVs were 10.67% and 13.49% , respectively. The normal reference value for seminal alpha-glucosidase activity detected with semi-automatic biochemistry analyzer ranged from 102.28 to 555.08 U/L. There was a significantly positive correlation between the semi-automatic biochemistry analyzer and the manual glucose oxidase method ( r = 0. 792, P 〈 0.01 ). Conclusion : The method of determining alpha-glucosidase activity in seminal plasma by semi-automatic biochemistry analyzer, with its simplicity, less cost of time and reagents, and more reliable result, could be applied to clinical laboratory medicine.
