Following standard chromosome preparation, cells are fixed to slides, hybridized overnight to appropriate DNA probe(s), washed, and counter-stained. 5-10 metaphases are evaluated using a fluorescence microscope and images are captured digitally using image analysis software.
Include pertinent medical findings on the requisition with suspected diagnosis and/or indication(s) for testing.
