Shipping Instructions

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

Necessary Information

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

2. The referring pathologist's name and phone number are required.

Specimen Required

Supplies: Pathology Packaging Kit (T554)

Specimen Type: Paraffin-embedded tissue block and slides

Note: 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.

Additional Information: If any imaging studies have been performed (ie, electron microscopy [EM], computed tomography [CT], magnetic resonance imaging [MRI], X-rays, etc.), include either on a CD (preferred) or as prints and send with the specimen.


For Hematopathology cases include:

1. Recent peripheral blood smear with complete blood cell count (CBC) report

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

3. Bone marrow aspirate (stained and unstained slides)

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

Testing Algorithm

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 comprehensive assessment. 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.
