Effect of time and temperature on anticoagulant-dependent pseudothrombocytopenia in Göttingen minipigs.

Background: A marked decrease in thrombocyte count was observed between subsequent measurements of the same EDTA blood sample in several minipigs, but little information was available explaining this finding.

Objectives: The objective was to evaluate the impact of several preanalytic variables on thrombocyte counts in minipigs, in order to improve understanding of the in vitro thrombocyte decrease observed.

Materials And Methods: Hematology blood samples from male and female Göttingen minipigs were collected using EDTA or citrate as an anticoagulant.
