血清类风湿因子(RF)测定常作为临床上诊断类风湿性关节炎的常规检查项目之一,并被普遍作为类风湿性关节炎(RA)实验室诊断的指标之一。RF作为1987年美国风湿病学会(ACR)修订的RA诊断分类标准中唯一的血清学指标,灵敏度较高,应用广泛,但特异度较差,不利于早期诊断与治疗。目前发现血清学指标抗-CCP抗体可在RA疾病中早期出现,且具有较高的特异度,有助于RA的早期诊断[1]。本研究选择276例到我院
Serum rheumatoid factor (RF) is routinely used as one of the routine tests for the clinical diagnosis of rheumatoid arthritis and is widely used as an indicator of laboratory diagnosis of rheumatoid arthritis (RA). As the only serological index of RA diagnostic classification standard revised by the American College of Rheumatology (ACR) in 1987, RF has high sensitivity, wide application but poor specificity, which is not conducive to early diagnosis and treatment. Serological markers of anti-CCP antibodies were found early in RA disease, and has a high specificity, contribute to the early diagnosis of RA [1]. This study chose 276 cases to our hospital
