Move over karyotypes—genetic disorder detection has vastly improved. Researchers are now using array CGH (aCGH), to quickly scan through an entire genome for imbalances. Because aCGH facilitates ...

Microarray analysis identifies more chromosome abnormalities than traditional karyotyping in prenatal testing. Microarrays will also identify findings of unclear clinical significance that should ...

A DNA microarray is a small manufactured chip spotted with up to tens of thousands of different oligonucleotide probes, intended to test how well a test sample of RNA binds to any of the probes.

Overview of the array comparative genomic hybridization process. Fragmented test DNA and reference (control ... to competitively hybridize to the microarray, consisting of oligonucleotides ...
