Short Answer Questions 1. The "fast hematocrit" involves withdrawing a very small amount of blood via a finger prick into a thin capillary tube, spinning the sample in a centrifuge so that it separates into its components, and then measuring the components. In Maggie's case, the total blood volume in the capillary tube is 20 mm, the packed cell volume (red blood cells) is 7.1 mm, and the plasma portion measures 12.9 mm. Calculate Maggie's first hematocrit. 2. In the ED, blood is withdrawn from the vein and into a test tube. The packed cell volume (RBCs) is 1.45 ml, and the plasma volume is 3.55 ml. Calculate Maggie's hematocrit in the ED.
