What is a "karyotype test"?

A karyotype test is a medical test used to examine a person’s chromosomes, which are structures in the cells that contain genetic information. The test involves taking a sample of cells, usually from blood, and then arranging the chromosomes in a specific order to look for any abnormalities in their number or structure. This test can help diagnose genetic disorders, such as Down syndrome or other chromosomal abnormalities, and is often used during pregnancy or when there are concerns about genetic conditions.
