RA is mainly defined by clinical criteria, in which systematic pathogenetic studies have been hampered by doubts about the presence of common pathogenetic mechanisms and the relative lack of unique laboratory findings. IgG rheumatoid factor has been reported to be present in sera of patients with rheumatoid arthritis both with and without IgM rheumatoid factor activity.
This is highly concentrated for minimum volume additions for control/calibrator manufacturing versus plasma or serum, saving money on other material components. Native-sourced, mimicking elevated RF human donor samples during assay interference studies.
Ideal for spike-interference studies in assay development and validation.
