Karyotype Test

What Affects the Test

If you are being treated for cancer, the results of a karyotype test may not be accurate. Chromosomes may be damaged by some types of cancer treatment.

What To Think About

  • If the results of karyotype are abnormal, other family members may be advised to have the test.
  • A sample taken by gently swabbing the tissues inside the cheek (called a buccal swab) sometimes is used for a karyotype test. But results from buccal swabbing are less accurate than other types of karyotype tests.
  • Sometimes a karyotype test is combined with other genetic tests to provide more specific information about genetic problems. To learn more, see the topic Genetic Test.
