Specimen:
Peripheral Blood, Bone Marrow, Fibroblasts, Other Tissue
Minimum:
5-10 cc adult, 2 cc infants of venous blood collected in a green-top vacutainer with sodium heparin. Invert tube to mix well. Label the tube with patient name and medical record number. DO NOT FREEZE OR CENTRIFUGE.
Delivery Instructions:
Submit specimen to laboratory as soon as possible after collection.
Specimen Instructions:
Provide details of clinical information. If a specimen is collected over the weekend, please page the technologist on call by dialing 1-888- 533-0186. When it stops ringing, enter your phone number, the '#' sign, and hang up.
Testing Schedule:
Specimens accepted in the lab Monday-Friday, 0800-1700. After hours specimens should be taken to specimen control and a message left on the lab voice mail. In the case of an emergency, follow the instructions on the lab voice mail.
Analytic Time:
Allow 5-7 days for final results.
Reference Range:
Varies for each probe (set). Unique sequence probes labeled with fluorochrome. Contact lab for details.
Comments:
This test can be used as an adjunct to chromosomal analysis for detection of submicroscopic/cryptic rearrangements in certain congenital disorders. Suitable for metaphase analysis only. Probes currently available include: Angelman syndrome, AneuVysion (prenatal screening for aneuploidy), Cri-du-chat, Deletion 22q syndromes, Miller-Dieker syndrome, Prader-Willi syndrome, Smith-Magenis syndrome, SRY(Yp11.3), STS[del(Xp22.3)], Subtelomere probe panel, Williams syndrome, Wolf-Hirschhorn syndrome.
