DNA extracted from the patient's peripheral blood is labeled and hybridized to the microarray. Following hybridization, the microarray is scanned and the intensity of signals is measured and compared to a reference data set. These data are used to determine copy number changes and regions of excess homozygosity. Chromosomal microarray data alone does not provide information about the structural nature of an imbalance and some abnormal results may be characterized by fluorescence in situ hybridization (FISH), limited chromosome analysis, or additional techniques.(Unpublished Mayo method)
