Test 70016 :
Hematopathology Consultation, Wet Tissue

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 not only assist to render accurate diagnosis but also could provide prognostic prediction and potential indication or guidance of therapy.


It is the Division of Hematopathology's mission to provide the highest possible level of diagnostic consultative service, trying to balance optimal patient care with a cost-conscious approach to solving difficult diagnostic problems for all patients. If a bone marrow consult is requested, the Mayo Clinic hematolopathologists will approach the diagnosis in the same way as Mayo Clinic's own in-house cases.

Useful For Suggests clinical disorders or settings where the test may be helpful

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


Obtaining special studies not available locally

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. The formal pathology report is faxed.


In our consultative practice, we strive to bring the customer 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 included.

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.

The laboratory will provide a pathology consultation.
