This study investigated the erythrocyte sedimentation rate (ESR) in an elderly population with the objective of establishing reference ranges and the diagnostic value of the ESR. Elderly blacks were randomly selected from communities in the Orange Free State. ESR determinations were done according to the Westergren method. Total protein, albumin, immunoglobulin and C-reactive protein (CRP) levels were measured on serum. Results were analysed by means of non-parametric statistical methods. In the group with normal CRP' and immunoglobulin levels it was found that 99% of values were below 44 mm/h for men and 62 mm/h for women. The sensitivity and specificity for these cut-off values (CRP used as 'gold standard') were 33% and 91% respectively for men and 75% and 89% respectively for women.
本研究对老年人群的红细胞沉降率（ESR）进行了调查，目的是确定参考范围以及ESR的诊断价值。老年黑人是从奥兰治自由邦的社区中随机选取的。ESR测定采用魏氏法。测定血清中的总蛋白、白蛋白、免疫球蛋白和C反应蛋白（CRP）水平。结果采用非参数统计方法进行分析。在CRP和免疫球蛋白水平正常的组中，发现男性99%的值低于44mm/h，女性低于62mm/h。这些临界值（以CRP作为“金标准”）的敏感性和特异性，男性分别为33%和91%，女性分别为75%和89%。
