Abstract

DUBOSCQ, Cristina et al. Comparison of mechanical vs. optical clot detection. Acta bioquím. clín. latinoam. [online]. 2016, vol.50, n.2, pp.205-213. ISSN 0325-2957.

The aim of this study was to determine whether two distinct methodologies based on optical or mechanical clot detection are comparable. Prothrombin time (PT), activated partial thromboplastine time (APTT) and fibrinogen results obtained with mechanical method using two different coagulometers are compared with those obtained by photo optical method within three hours of blood collection. The statistical analysis demonstrated an excellent correlation between optical or mechanical platform for TP, APTT and FBG. TP (%) showed (ACL TOP vs. STArt R=0.989; ACL TOP vs. Destiny Plus R=0.988), APTT: (ACL TOP vs. STArt R=0.938; ACL TOP vs. Destiny Plus R=0.989) y FBG (ACL TOP vs. STArt R=0.97; ACL TOP vs. Destiny Plus 0.984). The differences between optical or mechanical clot detection results are lower than the total error allowable in 95% of the studied samples. To conclude with, the three coagulometers evaluated have maintenance performed and are calibrated according to the international guidelines, and the results obtained with an optical or mechanical clot detection method are equivalent.
