Physician Attestation of Informed Consent
This germline genetic test requires physician attestation that patient consent has been received if ordering medical facility is located in AK, DE, FL, GA, IA, MA, MN, NV, NJ, NY, OR, SD or VT or test is performed in MA.
Preferred Specimen
5 mL whole blood collected in a sodium heparin (green-top) tube
Minimum Volume
3 mL whole blood
Other Acceptable Specimens
Whole blood collected in: Sodium heparin (royal blue-top), or sodium heparin lead-free (tan-top), EDTA (lavender-top) tube • Buccal swab collected in ORAcollect Dx OCD-100/OCD-100A • 2 mL saliva collected in 0GD-500 Oragene Dx collection kit (up to the "fill to" line on device, do not count bubbles)
Instructions
Whole blood, Critical NICU/Neonates 0.5 mL. All others 3-5 mL (3 mL minimum).
Green vacutainer (sodium heparin) or Lavender Top (EDTA). Ship at room temperature. Other vacutainer tubes containing sodium heparin are acceptable.
Buccal swab collected in ORAcollect-DX OCD-100/OCD-100A* (*Device contains insert), or Saliva collected in 0GD-500 Oragene Dx collection kit up to the "fill to" line on the device, do not count bubbles (2 mL minimum).
Specimen viability decreases during transit. Send specimen to testing lab for viability determination. Do not freeze. Do not reject.

Clinical Significance
Chromosomal microarray (CMA) detects aneuploidies, deletions and duplications below the resolution of chromosome analysis (karyotyping), and long continuous regions of homozygosity. CMA analysis can help to determine genetic causes of developmental delay (DD), intellectual disability (ID), dysmorphic features, congenital anomalies and pervasive developmental disorders. This test can also be ordered on parents to determine if a copy number variant in a child is inherited or de novo.
