patient results could be misleading in patient care and diag-nosis. On the other hand, the automated ESR methods offer
significant improvement in report turn-around time and in this way improve the service of the laboratory. StaRRsed has
many excellent technical properties but the complexity of the method is increased by the use of two anticoagulants, which
affect on RBC surface charge and correlation equations both in reaction time and temperature measurements. To simplify
and to improve the quality of the results, it would be better to use undiluted EDTA samples, 60 min measurement time,
and a calibration equation by Thomas et al. Since the ESR has a marked role globally in the diagnosis and follow-up in
patient care, the different ESR methods should better agree with each other because the reference ranges used are the
same
