Laboratory19q/19p chromosome deletion [# Ratio] in Tissue by FISH
Definition
The ratio of chromosome 19q arm deletions to chromosome 19p arm deletions. Results are used to diagnose oligodendroglioma brain tumors and to determine best treatment options. Tumors with 19q/19p ratio <0.80 and ≥26% deleted cells are deemed deleted for 19q.
