How are chromosome studies performed?

Chromosome studies are usually performed on dividing cells. When the cells divide, the chromosomes become visible and can be viewed with a microscope. To perform a chromosome analysis, patient cells are cultured in the laboratory. The dividing cells are harvested and placed on microscope slides. The chromosomes in the dividing cells are stained and analyzed at the microscope by a cytogenetic technologist under supervision of Dr. Zamani.
