    Patent number: 4887458
    Abstract: This invention is a semiautomatic hematocrit reader apparatus and method. A microhematocrit capillary tube is positioned under a movable cursor which is then moved along the length of the microhematocrit capillary tube. A switch is depressed to make a data entry at predetermined points along the length of a blood/plasma sample in the microhematocrit capillary tube. The relative distances travelled across the packed cell volume versus the plasma is electronically calculated and displayed automatically.
