COMPASS® is a comprehensive diagnostic solution, guided by a board-certified hematopathologist that provides an accurate, actionable, and definitive diagnosis for complex hematologic malignancies. Includes COMPASS® consultation report, clinical pathology evaluation, bone marrow morphology, flow cytometry, cytogenetics and/or fluorescent in situ hybridization (FISH), and molecular tests as medically necessary. Note: If an NGS profile is medically necessary and FLT3 by PCR is added on to provide faster results for the purpose of prompt therapy selection in cases of new or suspected AML diagnosis, the additional FLT3 test will be a client-bill only test. Please contact Client Services for more info.
