Aid in the diagnosis of rheumatoid arthritis (RA)1,2
Special Instructions
Not provided.
Limitations
The results of the RheumAssure panel should not be used in isolation but rather in conjunction with clinical assessments because RA can be diagnosed in patients without all tests being positive. Moreover, individual tests within the panel may vary in sensitivity, and the classification criteria require the presence of specific symptoms and joint involvement.
