目的通过同型号仪器不同检验因子和换算系数检验的俩组脑脊液数据,建立修正体系并验证,实现脑脊液与血清标本同台仪器同种校准物检测的可能性。方法将同型号的俩台电解质分析仪分别使用不同校准液标定,建立各自的检验因子和换算系数,同时检测脑脊液合格标本共156份312次,建立修正体系后检验脑脊液标本48份共96次,验证结果。结果通过C-1和C-2组数据比对建立好换算表格后,分别检测脑脊液标本,A组Cl-结果(109.4±3.5),与B组Cl-(125.3±3.9)间差异有统计学意义(P<0.01);使用修正体系换算后A组Cl-(123.5±4.3),与B组差异无统计学意义(P>0.05)。结论通过修正体系的建立,实现与血清标本同台仪器同种校准物检测的可能性,为检验同仁提供了有力的参考依据,但有条件实现脑脊液与血清标本分开检测的,应尽量使用各自匹配的校准物和检验体系。
Objective To establish a correction system and validate the data of two groups of cerebrospinal fluid (CSF) tested by different test factors and conversion factors of the same type instrument and verify the possibility of detecting the same calibrators of CSF and serum samples on the same instrument. Methods Different electrolytes of both models were calibrated with different calibrators to establish their own test factors and conversion factors. 156 cerebrospinal fluid samples were tested for 312 times. After the calibration system was established, 48 samples of cerebrospinal fluid were tested for 96 times, Validation results. Results After the conversion table was established by C-1 and C-2 data sets, CSF samples were tested respectively. The results of Cl- in group A (109.4 ± 3.5) and Cl- (125.3 ± 3.9) in group B were statistically significant (P <0.01). After the correction system was used, the Cl- (123.5 ± 4.3) in group A was not significantly different from that in group B (P> 0.05). Conclusion Through the establishment of amending system, the possibility of using the same calibrator to detect serum samples with the same instrument provides a strong reference for the test of colleagues. However, if the detection of cerebrospinal fluid and serum samples can be performed separately, it is better to use their own matching Calibration and inspection system.
