支气管肺泡灌洗液癌胚抗原检查的临床价值

目的：探讨支气管肺泡灌洗液（BALF）与血清癌胚抗原（CEA）及乳酸脱氢酶（LDH）对肺部良恶性疾患的鉴别诊断价值。方法：分别采用双抗体免疫法和速率治愈检测20例肺部感染性疾患及30例肺部恶性肿瘤病人BALF与血清CEA及LDH水平。结果：感染性有恶性BALF、血清LDH值有二者比值（KBLDH／SLDH）均无显著性差异（P＞0．05）。感染性及恶性BALF、血清CEA值及二者LL值（BcEA/ScEA）均具有显著性差异（P＜0．01）。其中对肺部恶性疾患的诊断敏感性为91％，特异性为100％。结论：同时测定BALF与血清CEA对良恶性肺部疾患具有鉴定诊断价值。

The value of using CEA and LDH of BALF to recognize and diagnose benign and malignant pulmonary disease

Objective: To detect the value of using bronohoalveolar lavage fluic (BALF) antigen (CEA) and lacticdehyrogenase (LDH ) to recogzize and diagnose benign and malignant pulmonary disease. Method: Using double antibodyradiation immunity and rate to check the level of BALF and serum CEA and LDH , Which of 30 examples of infections pulmonary disease and 30 examples of malignant pulmonary disease. Results: There is no remarkble difference between infectious and malignancy, BALF and serum LDH and their scale (p>0. 05). There is notable difference between infections and malignancy, BALF and serum CEA and their scale (p<0.01). The sensibility of diagnosis for malignant pulmonary disease is 91%, specificity is 100%. Conclusion: Simultanously detecting BALF and serum CEA have the recognizable and diagnostic value for benign and malignant pulmonarydisease.
