Micro Array: Comparative Genomic Hybridization (aCGH) with SNP

Methodology: 
Oligonucleotide (or oligonucleotide with SNP) genomic microarray platform; requires cell culture
Performed: 
Monday - Saturday
Reported: 
14 - 28 days
Use: 

This test provides a higher resolution level compared to chromosome-based (CGH) testing for genomic copy number variations.

Specimen Requirements: 

Peripheral Blood: Peripheral blood must be collected aseptically in sodium heparin tubes (usually green-top tubes) and immediately rotated thoroughly to prevent clotting. For infants, obtain approximately 2 cc. Obtain 5 - 7 cc for children and adults.

Note: A separate blood sample is required if a concurrent conventional blood chromosome and/or FISH studies are desired.

Do not freeze or fix samples in any manner contrary to the maintenance of cell viability. Maintain sample sterility; keep all specimens at room temperature; and deliver samples to the laboratory within 24 - 48 hours. Ship specimens at room temperature for overnight delivery.

  • Unacceptable Conditions:
    • Frozen specimens
    • Specimens greater than 48 hours old
  • Stability (collection to initiation of testing):
    • Ambient: 24 - 48 hours
    • Refrigerated: Unacceptable
Reference Values: 

By report; interpretive
