The Cytogenetics Laboratory is a CLIA-certified facility that offers comprehensive cytogenetic diagnosis for both constitutional and acquired chromosome abnormalities. It provides conventional karyotype analysis and fluorescence in situ hybridization (FISH) studies for the detection and characterization of chromosome abnormalities in clinical specimens and in established cell lines. The Cytogenetics Laboratory includes an American Board of Medical Genetics certified clinical cytogeneticist, highly knowledgeable laboratory supervisors, and well-experienced staff.
