Can you use a pedigree to help diagnose down syndrome?

Down syndrome is usually diagnosed through genetic testing, such as karyotyping, which identifies the presence of an extra chromosome 21. While a pedigree can indicate familial trends in genetic disorders, it does not confirm the presence of Down syndrome in an individual.
