Karyotype (product of conception)
Also known as: Chromosome Studies, Karyotype (tissues)« Back to test list
Chromosome analysis can detect abnormalities of chromosome number or structure. These abnormalities can provide diagnostic and prognostic information in many settings, including studies of aborted material and stillbirths.
Chromosome analysis can be used to assist with diagnosis/subclassification and to help determine prognosis.
This is an assay for heritable mutations. It may raise issues of ethics or consent that are different from most other investigations ordered in the routine care of a patient. The interpretation of the result may also be dependent on the family history and the interpretation of other studies.
Analysis of metaphase chromosomes by light microscopy. Chromosomes are counted, and examined for structural abnormalities.
This test can be requested by any medical practitioner.
Fresh material in a sterile container. Add sterile tissue culture medium to very small samples.
To help ensure the quality of the test, a genetic test should be done with a dedicated sample whenever possible i.e. a sample collected specifically for that test rather than a sample that is used for multiple tests.
We also recommend that the patient or another adult check the labelling of request forms and sample tubes.
