An electron microscope allows the user to magnify tissue samples up to 200,000 times.  This helps determine what kind of tumor, cancer or disease the cells are producing. The tissue is embedded into plastic then cut so thin that one could take a sheet of paper and cut its thickness 100 times.  These tiny samples are scooped together with a single eye-lash brush and placed on a copper grid for viewing with the Transmission Electron Microscope. 
Tests performed in the EM lab are:  Electron Microscopy (EM), Immunofluorescence (IF), Immunoperoxidase (IP) and Fluorescence In-Situ Hybridization (FISH) which helps the pathologist determine cancers and/or disease.  Also, the department tests for rejection of heart and kidney transplant biopsies.
New Immunoperoxidase instrumentation allows for quicker turn-around-time through mutli-continuous feed options where three runs can be started at differing times rather than having to wait for one run to complete before beginning the next one.
