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.
