Rates of abnormity (%) of ESR, CRP, RF, Anti-CCP in RA patients.

Variables	Positive (n)	Negative (n)	Rate of abnormity (%)
RF (IU/mL)	44	6	88
Anti- CCP (IU/mL)	42	8	84
ESR (mm/h)	33	17	66
CRP (mg/L)	16	34	32

Among the 50 patients, 44 cases were RF positive, abnormity rate was 88%. Forty-two cases were Anti-CCP antibody positive, the rate of abnormity was 84%. Thirty-three cases were ESR positive, abnormity rate was 66%. Sixteen cases were CRP positive, abnormity rate was 32%.

RF rheumatoid factor, Anti-CCP anti-cyclic citrullinated peptide, ESR erythrocyte sedimentation rate, CRP C-reactive protein.
