【摘 要】 目的:觀察分析外科術前血液標本放置不同時間及溫度對凝血四項測定結果的影響,為合理選擇標本送檢、檢測時間提供依據。方法:標本采集后檢驗科立即離心獲取血漿,即刻檢測凝血酶原時間(PT)、活化部分凝血活酶時間(APTT)、凝血酶時間(TT)和纖維蛋白原(FIB)。其余血漿標本分別置于室溫(20~25℃)、4℃冰箱保存,2h、4h、8h、12h、16h、24h檢測上述凝血四項。全部數據與即刻測定結果進行配對比較分析。結果:室溫PT、APTT即刻與室溫2h、4℃4h測定結果比較無差異(P>0.05),而標本放置室溫4h后與4℃8h后與即刻測定結果比較差異明顯(P<0.01)。室溫與4℃環境放置標本TT和FIB24h內測定結果無統計學意義(P>0.05)。結論:凝血四項測定應選擇室溫20~25℃室溫放置標本在采血后2h內完成;4℃保存標本在4h內完成。

【Abstract】 Objective To analyze the surgical preoperative blood specimen placed in different time and temperature influence on blood coagulation four determination results, provide the basis for the reasonable choice specimens inspection, testing time.Method Specimens collected clinical laboratory immediately after centrifugal plasma, immediately detect prothrombin time (PT), activated partial clotting enzyme live time (APTT), thrombin time (TT) and fibrinogen (FIB). The rest of the plasma specimens respectively under room temperature (20-25℃,4℃ refrigerator, 2h,4h,8h,12h,16h, 24 h test the above four coagulation.All data with paired comparison on the determination results immediately.Result PT, APTT, instantly at room temperature and room temperature 2 h, 4℃ for 4h determination results is no difference (P>0.05), and specimen placed at room temperature with 4℃ after 4h after 8 h compared with immediate determination results significant difference (P<0.01). TT and placed at room temperature and 4℃ environment specimen FIB24h determination results in no statistical significance (P>0.05).Conclusion Coagulation four determination should choose room temperature 20-25℃ placed within 2h after blood specimens at room temperature; 4℃ specimen within 4h to complete.

凝血酶原時間(PT)活分部分凝血活酶時間(APTT)纖維蛋白原(FIB)及凝血酶時間(TT)測定,凝血實驗已廣泛應用到血栓與止血性疾病的診斷、治療療效的觀察及病人術前、術中出血傾向的監測等諸多方面,其實驗結果的準確性顯得至關重要。資料報道血液標本送檢、放置時間與溫度對凝血四項測定結果的影響,標本采集不當與送檢時間是導致測定結果誤差的主要因素[1]。我們對45例外科手術前患者血液標本,置于室溫、4℃環境檢測凝血四項,判斷不同時間、不同溫度對結果的影響。
