A method for the examination of the same cell using light, scanning and transmission electron microscopy.

A method is described for preparing the same cell from a cytospin preparation for comparative investigation by light microscopy, scanning electron microscopy and transmission electron microscopy. A permanent numbered grid pattern was etched on a glass microscope slide to facilitate cell location in each microscopic mode. Data from one cell or group of cells was thus obtained from three sources. This method provides a useful adjunct to routine cytological diagnosis.
