Hematopathology Consultation, MCL Embed

Obtaining a rapid, expert opinion on unprocessed specimens referred by the primary pathologist

Obtaining special studies not available locally

A Mayo Clinic hematopathologist will provide a full bone marrow workup that includes an evaluation of the specimen and determination of a diagnosis provided within a formal pathology report.

Ancillary Testing:

Based on Mayo Clinic-approved algorithms and/or a staff hematopathologists' discretion, ancillary testing may be performed in order to render an accurate diagnosis and provide important prognostic information. These test results will be reported and separately billed. While reported separately, these results will continue to be considered and referred to in the Pathology final interpretation.

-Tier 1 testing (eg, cytochemical stains on bone marrow aspirate smear, immunohistochemical stains on bone marrow biopsy or clot sections, chromosome analysis, FISH, flow cytometry, and/or molecular testing) will be added as appropriate. Results will be incorporated into the pathology report, as well as, some separate standalone results may be released. All will be charged.

-Tier 2 testing (eg, next-generation sequencing: NGS or microarray testing) will only be added upon approval of the ordering physician/pathologist (client).

If ancillary testing (eg, flow cytometry) is desired by the client outside of this consultation, each test must be ordered separately. Tests ordered outside of the consultation may or may not be integrated into the final pathology report based on the staff hematopathologist's discretion.

If the volume of bone marrow aspirate is limited, prioritization of testing will be determined by the staff hematopathologist. Testing requested or suggested by the referring physician (immunostains, molecular studies, etc) may not be performed if deemed unnecessary by the reviewing staff hematopathologist.

Note: Calls are not routinely made; however, depending on the nature of the case, a call may be placed to the ordering provider or pathologist. These situations include, but are not limited to, a new diagnosis of acute leukemia or aggressive high grade lymphoma.
