Comparative genomic hybridization (CGH) (health)


A chromosomal screening technique that permits the detection of quantitative changes in chromosomal copy number without the need for cell culturing. It provides a global overview of chromosomal gains and losses throughout the whole genome (including extra, missing, and broken chromosomes), but cannot detect small changes in DNA sequence or changes in the imprinting state of a gene.
