Chromosome Analysis, Routine (Blood)
Chromosome analysis is an important component in the diagnosis and evaluation of genetic disorders. Chromosome abnormalities in which there is too much or too little genetic material can result in congenital malformations, intellectual disability, and aberrant sexual differentiation. Chromosome analysis can detect chromosome abnormalities such as trisomy, monosomy, triploidy, and marker chromosomes as well as balanced and unbalanced rearrangements.
Clinical Information
Routine chromosome analysis may be considered for indications of recurrent pregnancy loss, disorders of sexual differentiation, a family history of a known translocation or rearrangement, or an increased suspicion of aneuploidy.
Technical Information
For routine chromosome analysis a minimum of 20 cells are counted to determine the modal number, and a minimum of 5 cells are analyzed for chromosomal abnormalities from G-banded preparations.
Specimen Requirements
The accepted sample type is 3-4 ml of whole blood collected in a sodium heparin (green top) tube. For newborns and small infants, 2-3 ml of blood in a sodium heparin tube is acceptable. Blood kits are available by request.
Transport Instructions
Whole blood should be kept at room temperature and sent by courier or overnight shipping to arrive at the laboratory the next day. Do not freeze or refrigerate the specimen.
