Buccal Swab: ensure the sponge tip does not come in contact with any surface prior to collection. Transport buccal swab in ORAcollect Collection kit.
Cultured fibroblasts: Two T-25 flasks at 80 percent confluency. Fill flasks with culture media. Backup cultures must be maintained at the client's institution until testing is complete.

Storage/Transport Temperature

Preferred transport temps:
Whole Blood or buccal swab: Room temperature
Cultured fibroblasts: Room temperature: 2 days; Refrigerated: 2 days

Unacceptable Conditions

Frozen or clotted specimens.

Remarks

Documentation of the familial copy number variant (CNV) is required to perform targeted array analysis. Submit a copy of a relative's laboratory test report documenting the CNV for which testing is requested or include the ARUP accession number of the proband.
Counseling and informed consent are recommended for genetic testing. Consent forms are linked above.
New York Clients: informed consent is required with submission.
