Is it possible to have RA with high ESR 40, CPC 43 & IGA 4.15 reading but lowish RF 12 & CCP 3 readings. Rheum.not convinced RA as when scanned my joints showed little inflammation. Blood tests showing a Vit D deficiency also. My syptoms & family history point to RA. Just getting frustrated at time taking to get to the bottom of it all. Tajking more & more time of work due to extreme triedness & already on a 1st caution for my sickness with a final caution about to be serviced.
