Fluorescence In-Situ Hybridization (FISH-Paraffin Embedded Tumor)
Epic Lab Code: CYT54
Downtime Form: C-12 Cytogenetics Request
Shivanand R. Patil Cytogenetics & Molecular Laboratory (Dept. of Pediatrics)
W-101 GH
356-3877 (Laboratory)
Specimen(s):
Paraffin Embedded Tumor Tissue
Minimum:
4 unstained slides on charged slide, 1 H&E slide with tumor marked. All slides from the same block cut sequentially.
Delivery Instructions:
Submit specimen to laboratory as soon as possible after collection.
Testing Schedule:
Specimens are accepted Monday - Friday, 0800-1700. Provide details of clinical information. If the 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.
Turn Around Time:
Final results within 1 week.
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:
This test can be used for screening of sex chromosomes, for monosomies in cases such as glioma (eg.1p, 5, 7,19q, 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 (such as IgH/MYC, BCR/ABL, Igh/CCND1, IgH/BCL2) in solid tumors.

If the desired FISH probe is not listed, call the laboratory.
