Abstract:
A method for counting blood cells in a sample of whole blood. The method comprises the steps of: (a) providing a sample of whole blood; (b) depositing the sample of whole blood onto a slide, e.g., a microscope slide; (c) employing a spreader to create a blood smear; (d) allowing the blood smear to dry on the slide; (e) measuring absorption or reflectance of light attributable to the hemoglobin in the red blood cells in the blood smear on the slide; (f) recording a magnified two-dimensional digital image of the area of analysis identified by the measurement in step (e) as being of suitable thickness for analysis; and (g) collecting, analyzing, and storing data from the magnified two-dimensional digital image. Optionally, steps of fixing and staining of blood cells on the slide can be employed in the method.
Abstract:
A device for enabling the user of a clinical analyzer, such as, for example, an automated clinical analyzer, e.g., an automated hematology analyzer, to identify samples that require additional processing subsequent to an initial run through the clinical analyzer. The device can also indicate the location of sample containers to assist the user in finding a sample from a sample retention area. The device comprises a rack comprising a plurality of receptacles, each receptacle having a recessed area for holding a sample container, e.g., a sample tube. Each receptacle is associated with an indicator for signaling when a sample container in a given receptacle area requires additional processing.
