Sera from 263 newborns and infants suspected of congenital toxoplasmosis were tested for the presence of rheumatoid factor (RF) by the latex agglutination test, of which 40 were also tested by the enzyme-linked immunosorbent assay (ELISA). RF was detected in only one serum sample (0.38%), suggesting that false-positive results of the IgM-indirect fluorescent antibody test and the IgM-ELISA due to RF is most unusual in infancy.
对263名疑似先天性弓形虫病的新生儿和婴儿的血清进行乳胶凝集试验，检测类风湿因子（RF）的存在，其中40份血清还通过酶联免疫吸附测定（ELISA）进行检测。仅在一份血清样本中检测到RF（0.38%），这表明在婴儿期，因RF导致的IgM间接荧光抗体试验和IgM-ELISA假阳性结果极为罕见。
