目的:通过比较不同温度保存的自制混合血浆与正常混合血浆对血浆纠正试验的影响,探讨自制混合血浆在血浆纠正试验中的临床应用价值。方法收集凝血酶原时间(PT)≥18.0s和(或)活化部分凝血活酶时间(APTT)≥52.0s的血浆标本35份,分别与正常混合血浆(A组)、-80℃(B组)和-20℃(C组)保存的自制混合血浆按体积1∶1混合后做血浆纠正试验,即混合后立即测定PT和(或)APTT,37℃孵育1h后再次检测。计算35份标本可被正常混合血浆纠正的比例及3组的纠正率。结果88.57%(31/35)可被正常混合血浆立即纠正,4例未被纠正,其中1例孵育后比孵育前测定时间更加延长,占2.86%;3例孵育前后测定结果不变,占8.57%。在PT延长的血浆纠正试验中,各组之间纠正率差异无统计学意义(P>0.05)。在APTT延长的纠正试验中,孵育前A组、B组和C组的纠正率分别为(32.93±16.17)%、(27.56±23.48)%和(13.70±12.87)%,A组和B组之间纠正率差异无统计学意义(P>0.05),其余各组之间纠正率差异有统计学意义(P<0.05)。结论-80℃保存的自制混合血浆可代替商品化的正常混合血浆进行血浆纠正试验。
目的:通過比較不同溫度保存的自製混閤血漿與正常混閤血漿對血漿糾正試驗的影響,探討自製混閤血漿在血漿糾正試驗中的臨床應用價值。方法收集凝血酶原時間(PT)≥18.0s和(或)活化部分凝血活酶時間(APTT)≥52.0s的血漿標本35份,分彆與正常混閤血漿(A組)、-80℃(B組)和-20℃(C組)保存的自製混閤血漿按體積1∶1混閤後做血漿糾正試驗,即混閤後立即測定PT和(或)APTT,37℃孵育1h後再次檢測。計算35份標本可被正常混閤血漿糾正的比例及3組的糾正率。結果88.57%(31/35)可被正常混閤血漿立即糾正,4例未被糾正,其中1例孵育後比孵育前測定時間更加延長,佔2.86%;3例孵育前後測定結果不變,佔8.57%。在PT延長的血漿糾正試驗中,各組之間糾正率差異無統計學意義(P>0.05)。在APTT延長的糾正試驗中,孵育前A組、B組和C組的糾正率分彆為(32.93±16.17)%、(27.56±23.48)%和(13.70±12.87)%,A組和B組之間糾正率差異無統計學意義(P>0.05),其餘各組之間糾正率差異有統計學意義(P<0.05)。結論-80℃保存的自製混閤血漿可代替商品化的正常混閤血漿進行血漿糾正試驗。

Objective To explore the clinical application value of homemade plasma in the plasma correct test by comparing the influence of normal mixture plasma and homemade plasma storage at different temperatures .Meth‐ods 35 plasma samples of prothrombin time(PT)≥18 .0 s and/or activated partial thromboplastin time (APTT)≥52 .0 s were collected and mixed with the normal mixture plasma(group A) ,homemade plasma stored at -80 ℃(group B) and -20 ℃ (group C) with the proportion of 1∶1 respectively ,then PT and APTT were tested immedi‐ately ,and retested after 37 ℃ incubating for 1 h ,finally the correcting proportion in 35 samples and the correct ratio of these three groups were calculated .Results In the 35 cases of PT and/or APTT prolongation ,31 cases (88 .57% ) could be corrected by the normal mixture plasma and 4 cases were not corrected ,among them ,the detection time after incubation in 1 case(2 .86% ) was prolonged than that before incubation ,and the detection results before and after in‐cubation in 3 cases were unchanged ,accounting for 8 .57% .In the PT prolonged correction test ,there was no statisti‐cal difference in the correct ratio among 3 groups (P>0 .05) .In the APTT prolonged correction test ,the correcting ratios before incubation in the group A ,B and C were (32 .93 ± 16 .17)% ,(27 .56 ± 23 .48)% and (13 .70 ± 12 .87)%respectively ,there was no statistical difference in the correct ratio between the group A and B (P>0 .05) ,which in the other groups had statistical difference(P<0 .05) .Conclusion The homemade plasma stored at -80 ℃ can re‐place the commercialization normal mixture plasma for conducting the plasma correcting test .
