We're excited to share that Mayo Clinic Laboratories is now offering 14-3-3eta serum testing for rheumatoid arthritis (RA) in the United States. The test (Test ID: 1433E) is now available through Mayo Clinic Laboratories' diagnostic testing portfolio.
14-3-3eta is a joint-derived proinflammatory protein that complements established serological markers for RA, including rheumatoid factor (RF) and anti-CCP antibodies, and has shown value in earlier identification of RA and its association with disease severity and joint damage.
Mayo Clinic Laboratories, one of the most trusted names in laboratory medicine, joins the growing network of leading U.S. reference laboratories, offering 14-3-3eta testing, including Quest Diagnostics, Labcorp, ARUP Laboratories and Sonic Healthcare USA.
