DAS, or "Disease Activity Score," is a measure of the activity of rheumatoid arthritis. Based on the work of the Department of Rheumatology at the University Medical Centre at Nigmegen (Netherlands), a validated tool (formula) was developed to evaluate and track Rheumatoid Arthritis disease activity. By measuring the tender and swollen joint counts (TJC & SJC respectively), CRP (c-reactive protein) and General Health, the DAS 28-4 gives an estimate of disease activity, while the DAS 28-3 uses just the TJC, SJC & CRP. Clinicians, rheumatologists in training, educators and researchers use this tool everyday and now you can have it readily available on your Apple mobile device.
The following formulas are free for you to try.
• DAS28-CRP
• DAS28-CRP (3 Variable)
• DAS/DAS28 Converter
You may use these forever and never be nagged. There are no ads. Enjoy!
If you like what you see, upgrade to the "Pro" version via one-time in-app purchase. This will unlock all remaining formulas, including:
• DAS28
• DAS28 (3 Variable)
• DAS-CRP
• DAS-CRP (3 Variable)
• Original DAS
• Original DAS (3 Variable)
• CDAI
• SDAI
• Cumulative and Weighed RAPID3®}
