Chromosomes are present in every cell of human body and contain genetic material. Structural deformation of chromosomes may result in multiple health issues and diseases. Karyotype test or karyotyping is done to study such chromosomal defects under laboratory conditions. Besides structure, the test is also helpful in determining number of chromosomes in the sample cells or identifying mismatched chromosomal pair.
Karyotyping may be ordered in a number of cases. Infants born with birth are prescribed this test that helps the doctor to identify treatment courses. Women suffering from multiple miscarriages or still birth are also prescribed this test after all other probable factors have been ruled out. Choosing appropriate cancer treatments can also sometimes require a karyotyping. Diagnosing cases of children born with unclear sex find karyotyping useful.

The samples are then tested under laboratory conditions to determine chromosomal shape, size or number.
