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
Sometimes a karyotype test is combined with
other genetic tests to provide more specific information about genetic
problems. To learn more, see the topic
