Chromosome analysis is done on samples of blood, bone marrow, amniotic fluid and other tissue.
The following are instructions for the submission of samples to the Genetics Laboratory. Alcohol should be used as the disinfectant as betadine is toxic to cells. Fetal tissue can also be collected from multiple sites such as the kidneys, thymus, lungs, diaphragm, muscles, tendons, and gonads. An amniocentesis may also be performed should fetal demise be recognized before delivery. The initial test tube may be slightly bloody.
