2010 ACR/EULAR scoring criteria for RA. The following table provides the scoring criteria for different domains of evaluation. For each cell in the table for which the patient satisfies the condition, the cell is scored by the number of points at the top of the column in which it is found. The patient’s score is the sum of the scores for the individual cells. Patients with a total score of 6 or more points are diagnosed as having RA.
