Test Code NGSHM MayoComplete Myeloid Neoplasms, Comprehensive OncoHeme Next-Generation Sequencing, Varies

Useful For

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

 

Aiding in determining diagnostic classification

 

Providing prognostic or therapeutic information for helping guide clinical management

 

Evaluating patients with suspected VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome

 

Determining the presence of new clinically important gene mutation changes at relapse
