目的:探讨联合测定血清乳酸脱氢酶(LDH)和血小板计数(PLT)对急性白血病早期诊断的临床价值,以提高急性白血病初诊的准确性和特异性。方法对初诊的急性白血病患者同步测定LDH、PLT,通过受试者工作特征(ROC)曲线分析其临床性能,确立两者联合测定对急性白血病的诊断临界值。结果 LDH、PLT以及联合应用LDH与PLT的曲线下面积分别为0.908,0.811,其可信区间分别为0.852~0.965,0.728~0.893,0.877~0.969。结论运用ROC曲线分析简单有效,血浆LDH和全血PLT的检测对急性白血病早期诊断有较好的临床价值,以LDH>322 U/L,且PLT<72×109/L为诊断临界值较为适合。
目的:探討聯閤測定血清乳痠脫氫酶(LDH)和血小闆計數(PLT)對急性白血病早期診斷的臨床價值,以提高急性白血病初診的準確性和特異性。方法對初診的急性白血病患者同步測定LDH、PLT,通過受試者工作特徵(ROC)麯線分析其臨床性能,確立兩者聯閤測定對急性白血病的診斷臨界值。結果 LDH、PLT以及聯閤應用LDH與PLT的麯線下麵積分彆為0.908,0.811,其可信區間分彆為0.852~0.965,0.728~0.893,0.877~0.969。結論運用ROC麯線分析簡單有效,血漿LDH和全血PLT的檢測對急性白血病早期診斷有較好的臨床價值,以LDH>322 U/L,且PLT<72×109/L為診斷臨界值較為適閤。

Objective To study the clinical value of the joint determination of lactate dehydrogenases(LDH) and platelet count(PLT) in the early diagnosis of acute leukemia, in order to improve the accuracy and specificity of the early diagnosis of acute leukemia. Methods To do synchronous determination of LDH and PLT for the patients in Jiangmen Central Hospital, then to analyse the clinical performance of LDH and PLT joint determination by ROC curve , and establish its critical value in the diagnosis of acute leukemia. Results The area under the curve of LDH, PLT and LDH together with PLT were 0.908, 0.811 and 0.923. And their credible interval were 0.852-0.965, 0.728-0.893, 0.877-0.969. Conclusion ROC curve analysis is simple and effective, and the determination of plasma LDH and whole blood PLT has high clinical value in the early diagnosis of acute leukemia, and taking LDH>322 U/L, and PLT<72×109/L as the critical value of diagnosis is appropriate.
