ABSTRACT:
Centrifuged anticoagulated blood samples are analyzed under magnification in a centrifuge tube containing a layer-elongating insert, which tube is placed on a calibrated slide. The slide includes a slot in which the tube is placed. A calibrated scale is disposed adjacent to the slot for use in measuring various blood sample parameters, such as hematocrit, platelet count, and the like. Anemia and/or low platelet counts are indicative of potentially serious complications of malaria. Their detection will prompt a physician to consider the liklihood of serious illness due to malaria. The presence or absence of blood-borne parasites can also be determined using the procedures of this invention. Thus the device allows a blood sample to be analyzed for malarial parasites, and also allows measurement of hematicrit and platelet counts. The scale can be presented in a normal image when a simple lens magnification, such as a magnifying glass, is used to view the tube and slide; and can also be presented in mirror image when compound lens magnification, such as a microscope, is used to view the tube and slide.
