The effect of centrifugation time on cellular residues in fresh plasma.
Cellular residues were present in all fresh plasma prepared by a standard technique with centrifugation times of 5, 7, or 10 minutes. The amounts of cellular residues in the plasma were inversely proportional to the time of centrifugation. Platelet contamination was statistically different in the three times tested. In contrast, the residual amounts of erythrocytes and leukocytes were significantly different only when 5- and 10-minute centrifugation times were compared.
