Does the High Resolution Chromosome Testing/Karyotype also detect deletions and duplications on the X & Y chromsomes?
A. Large deletions or duplications will show up through this testing, but smaller deletions or duplications will not. Another testcalled the CGH Array , which is not widely used yet, looks at the X & Y chromsomes at a higher resolution and would detect the smaller deletions or duplications. CGH Array is a very new test and is not always covered by insurance.
