MayoComplete Myeloid Neoplasms, Comprehensive OncoHeme Next-Generation Sequencing, Varies
Use
This test is used for the evaluation of known or suspected hematologic neoplasms, specifically of myeloid origin, such as acute myeloid leukemia, myelodysplastic syndrome, and myeloproliferative neoplasms. It aids in determining the diagnostic classification, provides prognostic or therapeutic information to guide clinical management, and evaluates for new clinically significant gene mutation changes at relapse. It is also useful for evaluating patients with suspected VEXAS syndrome.
Special Instructions
Not provided.
Limitations
The test covers 47 genes but will not detect genetic abnormalities outside of these target areas. It detects single base substitutions and small insertions or deletions but does not identify gene rearrangements, fusions, copy number alterations, or large deletions. The assay does not differentiate between somatic and germline alterations for certain variant allele frequencies and may detect mutations not clearly distinguishable from tumor-associated mutations in older individuals. Results can be affected by prior treatment or stem cell transplantation, requiring correlation with clinical, histopathologic, and additional laboratory findings.
