Rheumatoid Factor, CSF
Use
Detection of rheumatoid factor (RF) in cerebrospinal fluid (CSF) can aid in the evaluation of central nervous system involvement in autoimmune or inflammatory processes, especially in cases where typical systemic manifestations are unclear. It may support the diagnosis of neuroinflammatory conditions when serologic RF levels are inconclusive or neurological symptoms predominate.
Special Instructions
Not provided.
Limitations
Limitations include the potential for non-specific binding or low concentration of rheumatoid factor in CSF which may yield indeterminate results. Factors such as contamination with blood, inadequate sample volume, or hemolysis may affect accuracy. Interpretation should consider concurrent serologic testing and clinical context.
