use of the b5 test in conjunction with erythrocyte sedimentation rate ( esr ) gave an increased specificity for active disease in that 87 % ( 35/40 ) of those who were b5-positive together with a raised esr had active disease : of those patients who were both b5-negative and had normal esr , 9 out of 108 ( 8 % ) had active disease .
