Karyotype Extended Banding Fluorescent in Situ Hybridization

LIke ThisLIke ThisLIke ThisLIke ThisLIke This

There are four different chromosome studies that can help determine if your child has a genetic birth defect. These are karyotype, extended banding chromosome studies, fluorescent in situ hybridization and chromosomal microarray analysis.

Chromosome studies are usually done from a blood sample, prenatal specimen, skin biopsy or another tissue sample. The results are reviewed by our specially trained doctors with degrees in cytogenetic technology and genetics. "Cytogenetics" is a word to describe the study of chromosomes.
