Whole-Genome SNP Microarray: Cytoscan HD Microarray

Test Information

The Affymetrix CytoScan HD platform allows for genome-wide detection of copy number gains and losses. In addition to detection of copy number variations (CNVs), this SNP array also allows for the analysis of loss of heterozygosity (LOH) which can be useful in identifying uniparental disomy (UPD) as well as autozygosity (identity by descent).

Specimen Requirements

5 to 7 ml of peripheral blood collected in an EDTA (lavender top) tube is the preferred specimen type. The minimal blood needed for reliable DNA isolation is 3 ml.

Additional specimen types include: saliva, extracted DNA, and solid tissue. Please contact the lab for more details.

Transport Instructions

The specimen should be kept at room temperature and delivered via overnight shipping. If shipment is delayed by one or two days, the specimen should be refrigerated and shipped at room temperature. Do not freeze the specimen. Samples collected on Friday can be safely designated for Monday delivery.

Prenatal Testing Information

Unexpected. If there is a term that sums up life it could very well be: unexpected. Life is full of unexpected moments. Some of these moments can be full of unexpected blessings while others may be full of unexpected obstacles. However, sometimes the unexpected can be both an obstacle and blessing at the same time; you just need someone to help you see both sides. The Greenwood Genetic Center is a place that helps shed some light on the...
