What is Array Comparative Genomic Hybridization (aCGH)?
Array Comparative Genomic Hybridization (aCGH) is a molecular cytogenetic technique that allows for the detection of genomic alterations, such as copy number variations (CNVs), across the entire genome. It is used to compare the DNA content of a test sample with a reference sample, identifying gains and losses of DNA segments that may be associated with diseases, including cancer.
