Abstract:
Objective To explore causes and solutions of false estimates of elevated serum creatinine in patients with Walden‐strom′s macroglobulinemia throug wet chemical enzymatic method .Methods 5 cases of patients hospitalized in the Bethune Inter‐national Peace Hospital were enrolled as subjects from 2010 to 2012 .The large molecular proteins were removal from serum sam‐ples collected from patients with Waldenstrom′s macroglobulinemia by using centrifugal ultrafiltration tube .The serum creatinine levels were detected through using the wet chemical enzymatic method ,wet chemical picric acid method and dry chemical enzymatic method before and after ultrafiltration ,and data were compared .Results Before ultrafiltration ,the levels of serum creatinine of 2 cases of patients with Waldenstrom′s macroglobulinemia detected by using wet chemical enzymatic method differed with those de‐tected by using wet chemical picric acid method and dry chemical enzymatic method .While there were no obvious differences be‐tween levels of serum creatinine detected by wet chemical picric acid method and dry chemical enzymatic method .While ,after ultra‐filtration ,no obvious differences were founded in levels of serum creatinine detected by the thress methods .Conclusion The large molecular proteins should be eliminated when using the wet chemical enzymatic method in the detection of serum creatinine levels , in order to avoid abnormal increase .And the wet chemical picric acid method and dry chemical enzymatic method could also be uti‐lized to determine the accuracy ,and provide reliable determination results .
