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.
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.
