Antinuclear antibody and rheumatoid arthritis factor test results were compared between two nearby hospitals of approximately the same size but with different patient populations. There were dramatic differences in percentage of positive results, titers, and patterns (for antinuclear antibody tests) between the two institutions.
对两家规模相近但患者群体不同的附近医院的抗核抗体和类风湿因子检测结果进行了比较。两家机构之间在阳性结果百分比、滴度和(抗核抗体检测的)模式方面存在显著差异。
