The diversity of factors involved in the ESR often ren-ders the interpretation of sedimentation rates difficult. Since
ESR results are indicative in nature rather than being pre-cise and accurate measurements of a specific analysis, it
can be considered that differences between results obtained by testing under ICSH conditions and from compensated
measurements taken after a shorter sedimentation time are acceptable and clinically insignificant. The differences be-tween StaRRsed and classic Westergren method that were observed in the present study are, in many cases, acceptable
and clinically insignificant. However, in long term patient follow-up, the greater than 30% difference observed in some
