Karyotype is a test to identify and evaluate the size, shape, and number of chromosomes in a sample of body cells. Extra or missing chromosomes, or abnormal positions of chromosome pieces, can cause problems with a person's growth, development, and body functions. Karyotyping is done to: 1  Find out whether the chromosomes of an adult have a change that can be passed on to a child. 2  Find out whether a chromosome defect is preventing a woman from becoming pregnant or is causing miscarriages.  Find out whether a chromosome defect is present in a fetus.
