本文报道用放射免疫法测定血浆皮质醇正常值及其昼夜节律改变,隔夜抑制试验和 ACTH 试验的结果。资料表明:单独测定一次皮质醇数值的意义不大,如测定其昼夜节律变化,结合兴奋或抑制试验就能比较可靠地诊断肾上腺皮质疾病。 This article reports the results of radioimmunoassay for determining plasma cortisol normal values ​​and their circadian rhythm changes, overnight inhibition and ACTH assays. Data show that: once a single determination of cortisol value is of little significance, such as the determination of its circadian rhythm, combined with excitement or inhibition test can be more reliable diagnosis of adrenal cortex disease.
