MANUFACTURE OF BLOOD COAT SLIDE FROM BLOOD SAMPLE

摘要

A method for preparing blood smear slides with substantially uniform separation of the blood cells from venous blood samples of different hematologic properties wherein the venous blood is diluted by mixing it with a substantially isotonic diluent in a proportion ranging from about one part blood to one part diluent, to four parts blood to one part diluent. A quantity of diluted blood is deposited on a slide which is then placed in a slide spinner operative to spin the slide a preselected acceleration, speed and time to produce a monolayer of blood cells on the slide. The method is adapted for preparing blood smears by automation regardless of the hematologic properties of the venous blood samples and the smears produced are especially suited for examination by automated scanning and analysis techniques. The uniformity and quality of these smears also facilitates fast accurate examination by conventional and manual microscopy.
