Specimen(s):
Tumor Tissue
Minimum:
Specimen obtained aseptically according to your protocol. Collect
specimen using sterile technique. DO NOT FREEZE OR CENTRIFUGE THE
SPECIMEN. This analysis can be done on interphase nuclei or on
metaphase cells. Contact the Cytogenetics Lab with questions.
Testing
Schedule:
Specimens accepted in the lab Monday-Friday, 0800-1700.
Turn Around
Time:
Preliminary results will be reported within 2-3 days and final results
within 1-2 weeks.
Reference Range:
Male: X and Y probe signals Female: two X probe signals For autosomes, the reference range varies for each probe (set). Suitable for interphase and metaphase analysis. Call lab for information.
Comments:
Epic code: CYT54
This test can be used for screening of sex chromosomes, for monosomies (eg., 5, 7, etc.), for trisomies (eg., +4, +8, +11, +12, +13, +14, +18, +19, +21, +22, etc.) or for detection of the gene fusion resulting from translocations in solid tumors.
If the desired FISH probe is not listed, call the laboratory.
