ABSTRACT
Objective To explore the influence of different testing methods on detecting value of to-tal cell volume. Methods 60 reusable dialyzers(low-flux dialyzer and high-flux dialyzer were 30 respec-tively) were enrolled. They were divided into the traditional testing group, the modified testing group and the automatic dialyzer reuse group with 20 dialyzers in each group according to different detecting methods, the results underwent analysis. Results The basic total cell volume of the traditional testing group, the modified testing group and the automatic dialyzer reuse group were (100.10±0.25) ml, (100.13±0.50) ml and (102.00±1.41) ml in 6LR dialyzer, while in 17R dialyzer, they were (113.67±1.30) ml, (118.67±1.30) ml and (119.93±1.77)ml respectively. The total cell volume of the dialyzer reuse in the traditional testing group, the modified testing group and the automatic dialyzer reuse group were (95.20±7.76) ml, (96.20± 7.22) ml and (102.80±4.26) ml in 6LR dialyzer, while in 17R dialyzer, they were (100.00±11.48) ml, (114.35±3.31 ) ml and (117.07±2.96) ml respectively. There was significant difference between the tradi-tional and the modified testing groups in high-flux dialyzers reuse. Conclusions The modified testing method can improve the accuracy of the testing of total cell volume in high-flux dialyzer reuse.
