  • Identification of blood elements using inverted microscopy
    Patent number: 9176121
    Abstract: A method of identifying the elements of a blood sample including placing an aliquot of blood on a transparent substrate such as a coverslip. The blood is allowed to stand and the cells to settle to form a layer or matrix. Inverted microscopy is used to identify the elements in the sample. Various forms of illumination may be used alone or in multiple combinations. The method improves the accuracy due to homogenous distribution of formed elements in the wet drop or aliquot, simplifies the method, lowers the cost of the test and results in a shortened analytical cycle time.
    Type: Grant

  • Method and apparatus for determining erythrocyte sedimentation rate and hematocrit
    Publication number: 20030113930
    Abstract: A method and apparatus is disclosed for determining the erythrocyte sedimentation rate and hematocrit simultaneously with the centrifugation of whole blood. A centrifuge separates the whole blood into its erythrocytes and its fluid portion. A video camera measures the levels of whole blood, erythrocytes and the fluid portion of the blood-and records the time of the formation of an interface between the erythrocytes and fluid portion. A monitor displays the results of the recording. Also disclosed are the method steps performed.
