Test Code NPMO NPM1 Mutation Analysis (Bone Marrow)

Important Note

Starting on 05/22/2017, the University of Chicago Molecular Pathology Laboratory launched a new NGS assay for the detection of mutations in Exon 11 of NPM1 gene. This test replaces the previous fragment analysis based qualitative assay and has a much improved analytical sensitivity (0.2% vs 5%).
