Rheumatoid Arthritis Patients

Rheumatoid arthritis (RA) patients with rheumatoid factor titer results above 900 IU/ml are urgently needed to donate plasma to support RA research and diagnostics.

Did you know that rheumatoid factor antibodies are found in plasma? These antibodies are necessary to manufacture positive controls for RA test kits. Because RA treatments work so well on most patients, it has become quite difficult to find plasma donors with high rheumatoid factor IgM levels. In turn, it has become more difficult to develop test kits – the same type of test kits used to diagnose those who now use RA medications.

If you or someone you know currently has a rheumatoid factor titer above 900 IU/ml, consider donating plasma at PlasmaLab in Everett. Your antibody-rich plasma will support the diagnostic community and fellow RA patients. Qualifying candidates may participate in multiple plasma donations throughout the year. Compensation is $185 for each completed plasma donation.
