[Dry chemistry method for measuring serum urea and creatinine].
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.


CONCLUSIONS
Dry chemistry method is rapid and accurate for emergent testing of serum urea and creatinine.
