摘要 目的:探討臨床凝血檢驗測量不確定度分析。方法:選取凝血檢驗標本100例,使用全自動血液分析儀檢測患者凝血酶原時間、纖維蛋白原、凝血酶凝固時間以及活化部分凝血活酶時間等指標。結果:當凝血酶原時間靶值為11.32s時,測量不確定值為1.24s;纖維蛋白原靶值為2.45g/L時,測量不確定值為0.89g/L;凝血酶凝固23.12s時,測量不確定值為1.68s;活化部分凝血活酶時間15.09s時,測量不確定值為0.44 s。結論:臨床工作中,通過對臨床凝血檢驗測量不確定度進行分析,明確患者各項指標之間的差異,在出現敏感指標改變時,能夠及時判斷患者病情,為其選擇對癥治療措施。因此,必須加強對凝血檢驗測量不確定度的掌握與分析,從而為臨床診治提供客觀依據。

Abstract Objective:To investigate the uncertainty analysis of clinical coagulation test.Methods:100 coagulation test specimenswere collected.automated blood analvzer was used to detect prothrombin time,fihrinogen,thrombin clotting time and activatedpartial clotting activity.Results:When the target time of prothrombin time was 11.32 seconds.the measiired uncertainty value was1.24 s.When the fibrinogen target value was 2.45 g/L,the measurement uncertainty value was 0.89g/L,and the thromhincoagulation time was 23.12.At the second.the measurement uncertainty was l.68 seconds.and when the partial thromboplastintime was 15.09 seconds.the measurement uncertainty was 0.44 seconds.Conclusion:ln the clinical work,by analyzing themeasurement uncertainty of clinical coagulation test.the difference between the various indicators of the patient can be clarified.When the sensitive inclex changes,the patients' condition can be judged in time,and symptomatic treatment measures can beselected for it.Therefore.it is necessary to strengchen the masterv and analysis of the measurement uncertainty of coagulation test,so as to provide an objective basis for clinic al diagnosis and treatment.

在醫學檢驗過程中,測量不確定度作用非常重要,這不僅是實驗室檢驗必須考慮的因素,也是臨床檢驗或比較前后檢測結果的重要依據。國內外規范以及標準中均明確指出,參考標準物質定值和參考測量結果,均需要給出測量不確定度[1-2]。而通過研究測量不確定度,則能夠對臨床凝血檢驗的結果進行判斷,并為患者提供準確的病情診斷結果及對癥的治療措施,從而實現患者病情的快速改善。為探究臨床凝血檢驗測量不確定度,2017年1月-2018年1月選取凝血檢驗標本100例,研究如下。
