WSLH Test Code:886F5
CPT Code:88271x2, 88275
Price:For pricing information, please call 608-262-0402.
Includes:FISH analysis of 200 cells for copy number of chromosome 1p compared to copy number of chromosome 1q
Methodology:Fluorescence in situ hybridization performed on interphase nuclei from paraffin embedded tissue using DNA probes (LSI 1p36/LSI 1q25; Vysis, Inc) covering the region including the TP73 and EGFL3 genes in 1p36 and probes covering the region including the ABL2 and ANGPTL1 genes in 1q25 as an internal control
Availability:Monday-Friday 7:45 AM - 4:30 PM, Saturday 7:45 AM - 12:00 PM
Turn-around Time:Approximately 5-8 days, with an average of 5 days. (Reports are issued Monday-Friday 7:45 AM - 4:30 PM)
Recommended Uses:Detection of relative loss of the short arm of chromosome 1. Aids in diagnosis of glial neoplasia including astrocytoma and oligodendroglioma.
Specimen Requirements:Paraffin embedded tissue: Five 4-micron sections on immunohistochemistry slides, the middle section stained with H&E.
