分离胶促凝管与普通干燥管在生化分析中的差异性研究

The study on the difference in biochemical analysis between applying the separation gel coagulation promoting tubes and the drying tubes in separating serum samples

目的用分离胶促凝管分离的血清与普通干燥管分离的血清进行生化项目的检测,将得到的结果进行比对、分析。方法采用分离胶真空采血管(检测组)与普通干燥采血管(对照组)进行随机采样,采集同一供血者的血样标本,一针两管,分离血清,即时进行生化指标的检测,对测定的结果进行分析比较;检测组原管置4℃24h后再一次对其进行检测,并将检测结果与即时分离胶分离的血清检测结果进行分析比较。结果检测组血清与对照组血清生化指标差异无统计学意义,置4℃24h后分离胶血清和即时分离胶血清测定结果比较,绝大部分生化指标差异无统计学意义,有较好的符合性,仅有一小部分生化指标差异有统计学意义。结论用分离胶促凝管分离的血清与普通干燥管分离的血清在临床检验指标上有较好的符合性,血液分离胶促凝管可以帮助检验科提供最佳品质的检测标本,使检验报告更精确。

Objective To compare and analyze the biochemical detection results of separated sera with the separation gel coagulation promoting tubes and the drying tubes. Methods Venous blood samples was collected from identical blood donors and randomly poured into the separation gel vacuum collective tubes （test group） and traditional drying collective tubes （control group）. After serum sepa- ration, timely biochemical detection was performed. The detection results were compared and analyzed. The samples of test group were detected once again after storage for 24 h at 4 ℃. The results were compared with those of timely biochemical detection with separation gel separated sera. Results The results from the test group and those from the control group had no significant difference. The most results from the sera storaging for 24 h at 4 ℃ and those from the fresh serum of the test group had good correspondence. Only a few of biochemical indicators had significant difference. Conclusion The biochemical detection with sera obtained by separation gel tubes and those collected by drying tubes has good correspondence. The separation gel tubes provide the clinical laboratory optimal blood samples and more accurate results.
