Test Code NGAMT MayoComplete Acute Myeloid Leukemia, Therapeutic Gene Mutation Panel (FLT3, IDH1, IDH2, TP53), Next-Generation Sequencing, Varies


Ordering Guidance


This test is a subset of the NGSHM / Myeloid Neoplasms, Comprehensive OncoHeme Next-Generation Sequencing, Varies test and focuses more specifically on the gene mutations that are most utilized for therapeutic management of acute myeloid leukemias (AML). If a wider gene mutation analysis is desired or the indication for testing is for a myeloid malignancy other than AML, then NGSHM should be considered.



Shipping Instructions


Peripheral blood and bone marrow specimens must arrive within 14 days of collection.



Necessary Information
