Test ID: NGAML
Next-Generation Sequencing, Acute Myeloid Leukemia, 11-Gene Panel, Varies
Testing Algorithm 
Delineates situations when tests are added to the initial order. This includes reflex and additional tests.
See Targeted Genes Interrogated by Next-Generation Sequencing, Acute Myeloid Leukemia, 11-Gene Panel in Special Instructions for a list of the genes and exons targeted by this assay.
Specimen Type Describes the specimen type validated for testing
Ordering Guidance
This test is a subset of the NGSHM / OncoHeme Next-Generation Sequencing for Myeloid Neoplasms test and focuses more specifically on the gene mutations that are most prevalent and clinically significant in acute myeloid leukemias (AML). If a wider gene mutation analysis is desired, or the indication is for a myeloid malignancy other than AML, then NGSHM / OncoHeme Next-Generation Sequencing (NGS), Hematologic Neoplasms should be considered.
Shipping Instructions
Bone marrow and peripheral blood specimens must arrive within 14 days of collection.
Necessary Information
The following information is required:
1. Clinical diagnosis
2. Pertinent clinical history, including disease phase (diagnostic, remission, relapse/refractory) and therapy status (especially if patient has received a hematopoietic stem cell transplant).
3. Clinical or morphologic suspicion
4. Date of collection
5. Specimen source
