癌胚抗原和铁蛋白测定对胸水鉴别诊断的价值

Value of Combined Testing Carcinoembryonic Antigen and Ferritin in Distinguishing Cancerous and Tuberculous Pleural Effusion

目的 探讨胸水中癌胚抗原 ,铁蛋白在癌性及结核性胸膜炎鉴别诊断中的价值。方法 分别采用血清铁蛋白免疫测定盒和癌胚抗原放射免疫测定盒检测胸水。结果 癌性胸水与结核性胸水的癌胚抗原分别为 17 4 8μg L和 6 93μg/L ,铁蛋白分别为 4 35 5 0 μg/L和 2 31 6 0 μg L。 结论 癌胚抗原和铁蛋白均阳性者多为癌性胸水。

Objective To discuss the value of combined tesing carcinoembryonic antigen(CEA) and ferritin in distinguishing cancerous and tuberculous pleural effusion. Methods Patient's carcinoembryonic antigen and ferritin were all measured by radioimmunoassay. Results The carcinoembryonic antigen's average level of cancerous pleural effusion and tuberculous pleural effusion was seperately 17.48 μg/L and 6.93 μg/L,the ferritin's average level was seperately 435.50 μg/L and 231.60 μg/L. Conclusion Pleural effusion with carcinoembryonic antigen and ferritin all positive is mostly considered cancerous.
