Question: how much plasma in 1 ml blood?
Answer: Popular Answers (1) As the g force or the time of centrifugation increases, there will be less platelets and WBC in the plasma phase. The hematocrit is usually 40-45% (not 7%), so from 600 ml of whole blood you can expect to get 600 x 55-60% = 330-360 ml of plasma.
