OBJECTIVE
To evaluate the dry chemistry method for measuring serum urea and creatinine.
METHODS
Urea and Creatinine were measured by dry and wet chemistry methods respectively. The results and the relativity between the two methods were compared.
RESULTS
The correlative factors were 0.996 and 0.995, respectively, implying fairly good comparability. The precision of the dry chemistry method was good, with the coefficient variation (CV) below 5%. With favorable accuracy, the recovery rate were 106.7% and 107.2%, respectively.
CONCLUSION
Dry chemistry method is rapid and accurate for emergent testing of serum urea and creatinine.
目的
评估检测血清尿素和肌酐的干化学方法。
方法
分别采用干化学法和湿化学法检测尿素和肌酐。比较两种方法的检测结果及相关性。
结果
相关系数分别为0.996和0.995，表明具有较好的可比性。干化学法精密度良好，变异系数（CV）低于5%。准确度良好，回收率分别为106.7%和107.2%。
结论
干化学法检测血清尿素和肌酐快速、准确，适用于急诊检测。
