## Abstract Penicillamine treatment of patients with rheumatoid arthritis (RA) leads to falling titers of agglutinating IgM rheumatoid factor (RF), but its effect on IgG RF has not been described. Using specific solid phase radioβimmunoassays, we have determined serial levels of IgM RF and IgG RF i

## Abstract In this report, solid phase radioimmunoassays that specifically measure IgG rheumatoid factor (RF) and IgM RF in absolute concentrations are described. Polyclonal RF preparations were utilized as standards, and as little as 40 ng/ml of IgG RF and 1 ng/ml of IgM RF were detected. The IgG
## Abstract The association of rheumatoid factor (RF) and lung disease in several immunologically mediated conditions has suggested that it may be physiopathologically relevant. Since previous reports in hypersensitivity pneumonitis (HP) have dealt mainly with the immunoglobulin M (IgM) RF measurem
