Karyotyping is the traditional method of chromosome
analysis. The test can be performed on a sample of blood,
marrow, amniotic fluid, or tissue. The specimen
is grown in tissue culture in the laboratory; and then
are harvested, chromosomes are stained, and viewed under
the microscope. Abnormalities can be identified through
the number of chromosomes or arrangement of chromosomal

The standard cytogenetic methodology utilized in this analysis does not routinely detect small rearrangements, microdeletions, and low level mosaicism.
