HelpTest Code NGSFX Reanalysis of Acute Myeloid Leukemia 4- or 11- Gene Panels, Additional Genes
Specimen Required
No additional specimen is required. This is a bioinformatics review of additional gene regions not analyzed in the previously ordered NGAMT / Acute Myeloid Leukemia, Therapeutic Gene Mutation Panel (FLT3, IDH1, IDH2, TP53), Next-Generation Sequencing or NGAML / Acute Myeloid Leukemia, 11-Gene Panel. Call 800-533-1710 for assistance with ordering.
Forms
1. Hematopathology Patient Information (T676)
2. If not ordering electronically, complete, print, and send an Hematopathology/Cytogenetics Test Request (T726) with the specimen.
Useful For
Comprehensive reanalysis of a larger set of genes/gene regions when a more targeted gene panel was previously performed in this laboratory
Evaluation of known or suspected hematologic neoplasms, specifically of myeloid origin (eg, acute myeloid leukemia, myelodysplastic syndrome, myeloproliferative neoplasm, myelodysplastic/myeloproliferative neoplasm, unexplained cytopenias) at the time of diagnosis or possibly disease relapse, to help determine diagnostic classification and provide prognostic or therapeutic information for helping guide clinical management
Determine the presence of new clinically important gene mutation changes at relapse
Testing Algorithm
Only orderable as a reflex. Reflex testing is available upon request within 6 months of original NGAMT / Acute Myeloid Leukemia, Therapeutic Gene Mutation Panel (FLT3, IDH1, IDH2, TP53), Next Generation Sequencing, Varies or NGAML / Acute Myeloid Leukemia, 11-Gene Panel, Varies sample submission.
This is a bioinformatics and variant review only for the added gene regions.
For a list of genes and exons targeted by this test see Targeted Genes Interrogated by Myeloid Neoplasms, Comprehensive OncoHeme Next-Generation Sequencing.

Interpretation
Detailed variant assessment and interpretive comments will be provided for all reportable genetic alterations.
If this test is ordered in the setting of erythrocytosis and suspicion of polycythemia vera, interpretation requires correlation with a concurrent or recent prior bone marrow evaluation.
