In order to obtain a value of hematocrit from the centrifuged blood sample in the capillary tube, one must refer to a scale plate, which is located directly under the samples in the centrifuge. The bottom of the packed red cell column is first lined up with the "0" line on the scale plate, and then the scale is moved under the sample until the top of the plasma column lines up with the"100%" line. In the example animation given below, watch as first one, and then a second sample tube moves over the grid. A black square on the right will give you a digital reading at a given point, but make sure that you note the right one!
