    摘要： A method for enumerating platelets within a blood sample is provided. The method includes the steps of: 1) depositing the sample into an analysis chamber adapted to quiescently hold the sample for analysis, the chamber defined by a first panel and a second panel, both of which panels are transparent; 2) admixing a colorant with the sample, which colorant is operative to cause the platelets to fluoresce upon exposure to one or more predetermined first wavelengths of light; 3) illuminating at least a portion of the sample containing the platelets at the first wavelengths; 4) imaging the sample, including producing image signals indicative of fluorescent emissions from the platelets, which fluorescent emissions have an intensity; 5) identifying the platelets by their fluorescent emissions, using the image signals; 6) determining an average fluorescent emission intensity value for the individual platelets identified within the sample; 7) identifying clumps of platelets within the sample using one or more of their fluorescent emissions, area, shape, and granularity; and 8) enumerating platelets within each platelet clump using the average fluorescent emission intensity value determined for the individual platelets within the sample.

    摘要： A method and apparatus for identifying reticulocytes within a blood sample is provided. The method includes the steps of: a) depositing the sample into an analysis chamber adapted to quiescently hold the sample for analysis, and the chamber has a known or determinable height extending between the interior surfaces of panels, which height is such that at least one red blood cell, or an aggregate of red blood cells, within the sample contacts both of the interior surfaces; b) admixing a supravital dye with the sample, which dye is operable to cause reticulin to fluoresce when excited by light of one or more predetermined wavelengths; c) imaging the sample using light that includes the one or more predetermined wavelengths that cause reticulin to fluoresce; d) imaging the sample using light that is absorbed by hemoglobin to produce values of optical density on a per image unit basis; and e) identifying reticulocytes within the sample using the image of the sample created with light that causes the dyed reticulin to fluoresce, and using the per image unit optical density values.

    摘要： A method for determining the hematocrit of a blood sample is provided that includes the steps of: 1) depositing the sample into an analysis chamber operable to quiescently hold the sample for analysis, the chamber defined by the interior surfaces of first and second panels and a height extending there between, wherein both panels are transparent, and the height is such that at least some of the red blood cells within the sample contact both interior surfaces of the panels and one or more lacunae within the quiescent sample extend between the interior surfaces; 2) imaging at least a portion of the quiescent sample, which sample portion contains the red blood cells and one or more lacunae to determine an optical density of the imaged portion of the sample on a per image unit basis; 3) selecting and averaging the optical density values of the image units aligned with the red blood cells contacting the interior surfaces, and assigning an upper boundary value of 100% to the average optical density value of those image units; 4) selecting the optical density values of the image units aligned with the one or more lacunae, and assigning a lower boundary value of 0% to the optical density values of those image units; and 5) determining the hematocrit of the sample by assigning relative values to the optical density value of each image of the imaged sample portion as a function of the upper and lower boundary values, and averaging the relative values.
