Deletion 19q, FISH, Glial neoplasia

Deletion 19q, FISH, Glial neoplasia
WSLH Department: Cytogenetics
WSLH Test Code:886F6
Includes:FISH analysis of 200 cells for copy number of chromosome 19q compared to copy number of chromosome 19p
Methodology:**(CPT Codes: 88271x2, 88275)** Fluorescence in situ hybridization performed on interphase nuclei from paraffin embedded tissue using DNA probes (LSI 19q13/LSI 19p13; Vysis, Inc) covering the region including the CRX, GLTSCR2 and GLTSCR1 genes in 19q13 and probes covering the region including the MAN2B1, ZNF443 and ZNF44 genes in 19p13 as an internal control
Availability:Monday-Friday 7:45 AM - 4:30 PM, Saturday 7:45 AM - 12:00 PM
Turn-around Time:Approximately 5-6 days. (Reports are issued Monday-Friday 7:45 AM - 4:30 PM)
Recommended Uses:Detection of relative loss of the long arm of chromosome 19. Aid in diagnosis of glial neoplasia including astrocytoma and oligodendroglioma.
Contraindications: 
Specimen Requirements:Paraffin embedded tissue: Five 4-micron sections on immunohistochemistry slides, the middle section stained with H&E.
Collection Kit/Container:
