A serum ferritin concentration of below 15 microgram/l is accepted as indicating diminished iron reserves in an otherwise normal person. In patients with inflammatory disease this lower limit of normality may be inappropriate as inflammation may directly stimulate the production of ferritin protein. Results obtained in a survey of 150 patients with early inflammatory joint disease suggest that a ferritin concentration of 55 microgram/l is a more appropriate lower limit of normality.
血清铁蛋白浓度低于15微克/升被认为表明在其他方面正常的人铁储备减少。在患有炎症性疾病的患者中,这个正常下限可能并不合适,因为炎症可能直接刺激铁蛋白的产生。对150例早期炎症性关节病患者的调查结果表明,铁蛋白浓度55微克/升是更合适的正常下限。
