Chromosomal Microarray (MicroarrayDx)
Use
Chromosomal Microarray (MicroarrayDx) is used to detect genomic gains and losses (copy number variants) across the genome, aiding in diagnosis of chromosomal abnormalities and deletions/duplications associated with inherited and developmental disorders.
Special Instructions
Order requires completion of GeneDx Cytogenomics Test Requisition Form. When performed in prenatal context, maternal cell contamination control via parental samples (blood or buccal) may be required. See Cytogenomics Test Requisition Form for collection labeling and parental sample instructions.
Limitations
The test is a comparative genomic hybridization microarray and may not detect balanced rearrangements or low-level mosaicism. Test code, gene content, and technical limitations may change and the most current specifications are available on the GeneDx website.
