摘要: 目的

探讨科宝Palio 300型尿全自动生化分析仪(简称Palio 300)对于5种尿微量蛋白项目的检测性能。

方法

同时采用Palio 300和西门子BN-prospec特定蛋白仪(简称BN-prospec)检测120例患者尿微量白蛋白(mAlb)、尿α1微球蛋白(α1-MG)、尿β2微球蛋白(β2-MG)、尿转铁蛋白(TRF)、尿免疫球蛋白G(IgG),比较各项测定结果。按照项目分别配置中值及高值混合尿液,充分混匀后每份样本在Palio 300上重复测定20次,计算这5个项目的变异系数(CV)。

结果

Palio 300上5个项目除β2-MG CV为8.66%外,其余4项CV均<6.00%;且与BN-prospec的检测结果一致性较好,5个项目的r均>0.9(其中mAlb为0.953、 α1-MG为0.915、β2-MG为0.927、TRF为0.918、IgG为0.935, P均<0.001)。

结论

Palio 300具有较好的重复性,在测定5种尿mAlb项目时,与BN-prospec相关性良好。

Abstract: Objective

To evaluate the performance of Cobio Palio 300 urine automatic biochemical analyzer (Palio 300) for the determinations of 5 kinds of urinary micro-proteins.

Methods

By Palio 300 and Siemens BN-prospec, 120 urine samples were determined for urinary micro-albumin (mAlb), α1 microglobulin (α1-MG), β2 microglobulin (β2-MG), transferrin (TRF) and immunoglobulin G (IgG). The results were compared and analyzed statistically. In addition, the medium-value and high-value mixed urine was used for these items. Each sample was determined repeatedly for 20 times, and the coefficient of variation (CV) was calculated.

Results

Four items showed CV<6.00%, except β2-MG CV=8.66%. The results were consistent with those of Siemens BN-prospec. The correlation coefficients (r) of 5 items were >0.9 (mAlb 0.953, α1-MG 0.915, β2-MG 0.927, TRF 0.918 and IgG 0.935, P<0.001).

Conclusions

Palio 300 has good repeatability, and its result is consistent with Siemens BN-prospec in the determinations of 5 urinary micro-proteins.
