The hematocrit is slightly more accurate as the PCV includes small amounts of blood plasma trapped between the red cells. If 1 "unit" of packed red blood cells is approximately 300 mL, this becomes a change of hematocrit of 1.9% +/- 1.2% per "unit" of blood. The vol of ea Unit is approx. In the absence of heavy consumption or bleeding one unit of cryoprecipitate per 10 kg of body weight raises plasma fibrinogen concentration by ~ 50 mg/dL.
