In this study we aimed to detect the effect of different centrifugation temperatures on coagulation parameters in the emergency laboratory. Duplicate samples were collected into sodium citrate tubes from 45 patients and centrifuged concurrently with non-cooling (group 1) and cooling centrifuges (Group 2) in Ankara Numune Training and Research Hospital emergency laboratory. Inner temperatures of the centrifuges were recorded during the study. Afterwards, PT, aPTT, D-dimer and fibrinogen values were determined. No statistically significant difference was detected between groups for any of the parameters tested (PT, aPTT, D-dimer and fibrinogen) (p> 0,05). Results of the present study show that there is no significant effect of internal temperature of the centrifuge device used on blood coagulation parameters.
Key words: Coagulation, centrifugation, temperature, pre-analytical phase, sample handling
