Nov 30, 2023: New Nordic Biobank profiles added & Special Offer through December 2023

- The Swedish Rheumatology Quality Register (SRQ) is a national quality register with the aim of continuously improving the treatment and follow-up of patients with rheumatic diseases. SRQ was started in 1996, mainly for patients with RA, but over time it has been expanded to cover several other rheumatic diseases including ankylosing spondylitis (AS) and psoriatic arthritis (PsA), myositis, systemic lupus erythematosus (SLE) and additional conditions.
