Early and Established Rheumatoid Arthritis (RA) Panel

RAPANEL
Example Reports
Negative
Positive

Ordering Recommendation

Use to identify rheumatoid arthritis (RA). This panel may have enhanced sensitivity due to the inclusion of 14-3-3 eta protein alongside conventional rheumatoid factor (RF) and anticyclic citrullinated peptide (anti-CCP) antibody. 14-3-3 eta is also used to stratify disease activity and monitor treatment effectiveness.
