摘要
目的:探讨临床标本采血量的准确性对凝血酶原时间(PT)、活化部分凝血活酶时间(APTT)测定的影响。方法:用BE-RockRotor全自动血凝仪和配套试剂分别对15例临床患者不同抽血量标本进行检测,观察不同的采血量对PT、APTT检测结果的影响,并将所得检测结果采用统计方法处理。结果:与标准采血量为1.8mL相比,采血量大于或小于1.8mL时测得的PT、APTT结果有显著性差异。结论:临床标本采集量对凝血系统检测结果的准确性有直接影响;必须严格按照标准采血量规定采集标本,才能确保凝血系统检测结果的准确,为病人疾病的诊断提供可靠的实验室依据。
Objective： To investigate the influence to the results of prothrombin time（PT） and activated partial thromboplastin time（APTT） causing by different volumes of clinical blood collection. Methods： The PT and APTT of 15 patients were assayed, respectively, by the BE-RockRotor instrument using different volumes of clinical blood collection and the data were analyzed statistically. Results： The results of PT and APTT which the volumes of clinical blood collection were 〉1.8 mL or 〈1.8 mL were different significantly in statistics to those which the volumes were accurate. Conclusion： The results of PT and APTT were influenced by the volumes of clinical blood collection. So using the standard blood collection procedure for blood clotting system determining is necessary and can offer the accurate results for clinical diagnosis.
