Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

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 or at a staff hematopathologist's discretion, ancillary testing may be performed to assist in rendering an accurate diagnosis and provide important prognostic information. These test results (eg, cytochemical stains on bone marrow aspirate smear, immunohistochemical stains on bone marrow biopsy or clot sections, chromosome analysis, fluorescence in situ hybridization: FISH, flow cytometry, microarray, molecular and/or next-generation sequencing (NGS) testing) will be reported and billed separately. While reported separately, these results will continue to be considered and referred to in the pathology final interpretation.

 

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. To contact a Mayo Clinic Hematopathologist, call the Hematopathology Communications team at 507-284-5600.

 

Embedding at the client site may delay specimen arrival at Mayo Clinic Laboratories and preclude the ability to perform some ancillary testing due to specimen stability.

Clinical Information Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test

Diagnosis of a hematologic disease requires thorough and accurate morphologic examination of peripheral blood, bone marrow, and interpretation of ancillary testing results (eg, cytochemistry, immunohistochemistry, flow-cytometric immunophenotyping, chromosome analysis, FISH testing, and molecular genetics) by a highly qualified hematopathologist. With recent advent of new understanding and more treatment options, more ancillary tests are available. Efficient utilization and accurate interpretation of these tests are crucial in patient care. These tests can assist in rendering an accurate diagnosis and could also provide prognostic prediction and potential indication or guidance of therapy.

Reference Values Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.

An interpretive report will be provided.

Interpretation Provides information to assist in interpretation of the test results

Results of the consultation are reported in a formal pathology report that includes a description of ancillary test results (if applicable) and an interpretive comment. When the case is completed, results may be communicated by a phone call.

 

This consultative practice strives to bring the physician and patient the highest quality of diagnostic pathology, in all areas of expertise, aiming to utilize only those ancillary tests that support the diagnosis in a cost-effective manner, and to provide a rapid turnaround time for diagnostic results.

Cautions Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances

All appropriate stained/unstained slides, biopsy tissue and aspirate are required in order to make a diagnosis. The referring pathologist's and clinician's name and phone numbers are essential. Specific diagnosis may require correlation with clinical information; this information must be sent with the specimen.
