I take it you've googled " Chondrocalcinosis "? It shows it as an inherited metabolic disorder where certain chemicals are deposited in one or more joints. The ESR and CRP just give a guide to the inflammation in your body. My little booklet shows normal ESR should be under 20 and normal CRP should be under 10, but as I say, they are only guides!
