Can osteoarthritis, rhematoid arthritis and fibromyalgia cause elevated crp levels?

Yes: C reactive protein is a more sensitive marker of inflammatory conditions; can be elevated in aging, osteo and rheumatoid arthritis types, myocardial infarction, ulcerative colitis, chronic kidney disease .It is predictive of cardiac risk. Increased body mass index increases crp.

Not so! Fibromyalgia: Fibro and osteoarthritis are non inflammatory! CRP is not elevated with these. If CRP is elevated, look elsewhere!
