Frequently asked question: What are chromosomal and DNA analyses?

Genetic testing is performed if a syndrome or another genetic abnormality is suspected. The length of time you must wait to get the result depends on the type of test. An urgent analysis of the number of chromosomes takes a few days; a standard analysis can easily take a week. Testing genes for abnormalities usually takes several weeks; it is, after all, very time-consuming and precise work.
