本文测定健康成人血清铁蛋白。男性,女性分别为93.7及64.0μg/L,60岁以上老年为103.14μg/L。肺炎、结核、肺癌患者血清铁蛋白男性、女性间无明显差异,但分别高于同性别正常组,也均高于正常老年组;尤其肺癌组明显高于其他各组。同一患者胸水铁蛋白高于血清铁蛋白。肺癌胸水铁蛋白最高。血清及胸水铁蛋白测定可作为炎症、结核、肺癌诊断方法之一。 This article measures healthy adult serum ferritin. Males and females were 93.7 and 64.0 μg/L, respectively, and those older than 60 were 103.14 μg/L. There was no significant difference in serum ferritin between male and female patients with pneumonia, tuberculosis, and lung cancer, but higher than that of the normal sex group and higher than that of the normal elderly group. The lung cancer group was significantly higher than other groups. In the same patient, pleural ferritin is higher than serum ferritin. Pleural fluid ferritin is highest in lung cancer. Serum and pleural fluid ferritin determination can be used as one of diagnostic methods for inflammation, tuberculosis, and lung cancer.
