Sera from nine patients with cryptococcal infections and from four with rheumatoid arthritis and positive rheumatoid factor were examined for the presence of cryptococcal capsular antigen by the latex agglutination method. Ethylenediaminetetraacetic acid-heat treatment of the sera before testing possibly increased sensitivity as compared with the untreated sera, and the interfering rheumatoid factor activity was eliminated.
采用乳胶凝集法检测了9例隐球菌感染患者以及4例类风湿性关节炎且类风湿因子呈阳性患者的血清中隐球菌荚膜抗原的存在情况。与未经处理的血清相比,检测前对血清进行乙二胺四乙酸热处理可能会提高检测灵敏度,并且消除了干扰性类风湿因子活性。
