Pathology Consultation

Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.

This request will be processed as a consultation case. An interpretation, which includes an evaluation of the specimen and determination of a diagnosis, will be provided within a formal pathology report. Second opinion regarding diagnosis will be rendered by staff pathologists, often in consultation with colleagues who have expertise in the appropriate subspecialty areas. Appropriate additional stains and other ancillary testing may be performed in order to render an accurate diagnosis. These additional stains/tests ordered will have the results included within the final pathology report and will be charged separately.


Note: Special stains and studies performed on the case should be sent with the case for review. In order to determine an accurate diagnosis, some of these stains or studies may be deemed to warrant being repeated (and charged) at the reviewing Mayo pathologist's discretion. In addition, testing requested by the referring physician (immunostains, molecular studies, etc) may not be performed if deemed unnecessary by the reviewing Mayo pathologist. For all pathology consultations, ancillary testing necessary to determine a diagnosis is ordered at the discretion of the Mayo pathologist.


-If requesting a peripheral blood smear evaluation, order SPSM / Morphology Evaluation (Special Smear).


See Pathology Consultation Ordering Algorithm in Special Instructions.

Specimen Type Describes the specimen type needed for testing


Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.

A preliminary pathology report and brief history are required for all Pathology Consultations.


Specimen Type: Tissue

Container/Tube: Pathology Packaging Kit (T554)

Collection Instructions: Submit hematoxylin and eosin (H and E) and all special stains performed on the case. Include unstained slides and/or a formalin-fixed, paraffin-embedded tissue block if it is anticipated that additional stains or ancillary testing may be necessary. Unstained slides for immunohistochemistry should be charged, if possible, as not all immunohistochemical stains can be performed on uncharged slides. If electron microscopy (EM) has been performed, include EM images (either on a CD or as prints).


Specimens needed to provide a complete Hematopathology consultation:

1. Recent peripheral blood smear with CBC report

2. Bone marrow biopsy/clot (block and stained slides)

3. Bone marrow aspirate (stained and unstained slides, and liquid)

4. All pending and final reports for ancillary testing on above specimens

Additional Information:

1. A brief explanatory note or consultative letter is also recommended.

2. Attach the green "Attention Pathology" address label included in the kit to the outside of the transport container.

3. This test is not intended for use with wet tissue (tissue that still needs to be processed).
