Note: Results are presented as mean volume from five evacuated tubes producers – BD Vacutainer®, Becton, Dickinson and Company; Vacuette®, Greiner Bio-One; Vacumed®, FL Medical; Vacutest®, Kima; and S-Monovette, Sarstedt using the vacuum technique – filled with a solution with density and viscosity like whole blood. Volumes (ml) reported by the evacuated tube manufacturer at sea level (0 m) are presented in bold. Altitudes are referred in meters above sea level. All tubes used were 13×75 mm.
