Trait: rheumatoid factor measurement

Experimental Factor Ontology (EFO) Information
Identifier EFO_0005767
Description quantification of rheumatoid factors, antibodies in the serum of individuals with rheumatoid arthritis that react with antigenic determinants or immunoglobulins that enhance agglutination of suspended particles coated with pooled human gamma -globulin. Rheumatoid factors also occur in other autoimmune and certain infectious diseases.

Performance Metrics

Disclaimer: The performance metrics are displayed as reported by the source studies. It is important to note that metrics are not necessarily comparable with each other. For example, metrics depend on the sample characteristics (described by the PGS Catalog Sample Set [PSS] ID), phenotyping, and statistical modelling. Please refer to the source publication for additional guidance on performance.
