Karyotype Test

Chromosome Analysis

What To Think About

• Sometimes a karyotype test is combined with other genetic tests to provide more specific information about genetic problems. For more information, see the medical test Genetic Test.
• If the results of karyotype are abnormal, other family members may be advised to undergo testing.
• A sample taken by gently swabbing the tissues inside the cheek (called a buccal swab) sometimes is used for a karyotype test. However, results from buccal swabbing are less accurate than other types of karyotype tests.
• Since the information obtained from a genetic test can have a profound impact on your life, you may want to see a doctor who specializes in genetics (geneticist) or a genetic counsellor. This type of counsellor is trained to help you understand your risk for having a child with an inherited (genetic) disease, such as sickle cell disease, cystic fibrosis, or hemophilia. A genetic counsellor can help you make well-informed decisions. Ask to have genetic counselling before making a decision about a genetic test.
