Ordering Guidance
For a pathology consultation on paraffin embedded tissue and slides only (ie, no wet tissue being sent to be processed), order PATHC / Pathology Consultation.
Shipping Instructions
Vitreous fluid/aqueous humor specimens: ship overnight; Attention: Ophthalmic Pathology Working Group. Call 800-533-1710 to request an Expedite on this order since vitreous fluid will have no fixative and needs to reach the laboratory as quickly as possible.
Attach the green pathology address label to the outside of the transport container.
Necessary Information
The following information is required:
1. All requisitions must be labeled with:
-Patient name, date of birth and medical record number
-Name and phone number of the referring pathologist or ordering physician
-Anatomic site and collection date
2. All specimens must be labeled with:
-Two patient identifiers (first and last name, date of birth or medical record number)
-Specimen type and anatomic site
3. A brief patient history is essential to achieve a consultation fully relevant to the ordering physician's needs.
4. A preliminary pathology report is preferred, if available, in order to ensure that the specimen is known to a referring pathologist.

Specimen Type: Cardiac explant
Supplies:
-Pathology Packaging Kit (T554)
-Refrigerate/Ambient Shipping Box, 5 lb (T329)
Specimen Volume: Entire specimen
Collection Instructions:
1. Fix entire explant specimen in formalin for a minimum of 24 hours.
2. Following fixation, lightly wrap specimen in formalin-soaked paper towel, place in a leak-proof sealable bag with a small amount of formalin, seal, and ship ambient in a sturdy shipping container (ie, Refrigerate/Ambient Shipping Box, 5 lb).
Additional Information: Include the last pretransplantation echocardiogram with report and images as well as all other relevant clinical documents.
Specimen Type: Enucleated eye
Supplies:
-Pathology Packaging Kit (T554)
-Formalin - 10% Histo Prep, 45 mL (T117)
Specimen Volume: Entire specimen
Collection Instructions:
1. Immediately after removal, place specimen in approximately 300 mL of 10% neutral buffered formalin.
2. Enucleated eye should not be opened or punctured.
3. After 48 hours in the originating laboratory, the specimen should be transferred from the larger, 300 mL container to a smaller container with fixative (Formalin - 10% Histo Prep, 45 mL) to be shipped without risk of leakage.
Specimen Type: Iris, conjunctiva, cornea, and other small biopsies from eye
Supplies:

Specimen Volume: Entire specimen
Collection Instructions:
1. Obtain biopsy.
2. Place iris, conjunctiva, cornea, and other small biopsies on a paper mount (a piece of filter paper or other porous paper). This helps to keep the specimen from curling when it is fixed.
3. Immediately but gently place specimen (on the paper mount) into 10% formalin, approximately 20 times the volume of the biopsy (Formalin - 10% Histo Prep, 45 mL).
4. In cases where margins are important, placing sutures at the margins of resection with accompanying explanatory draft will help orientation of the specimen in the lab.
Specimen Type: Vitreous fluid/Aqueous humor
Supplies:
-Pathology Packaging Kit (T554)
-Sarstedt Aliquot Tube, 5 mL (T914)
Specimen Volume: Entire specimen
Collection Instructions:
1. Obtain liquid specimen.
2. Place the liquid (vitreous or aqueous) concentrate into a small tube with a screw-top cap. Seal the tube tightly.
3. Put the specimen immediately on a refrigerated cool pack (not dry ice or frozen cool pack).
4. If a washing (diluted) is available, it can also be sent in similar manner.
Specimen Stability Information: Refrigerated

Clinical Information

Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test
Mayo Clinic in Rochester, Minnesota is staffed by pathologists whose expertise and special interests cover the entirety of Pathology, from surgical pathology with all of its respective subspecialty areas, to Hematopathology, Renal Pathology, and Dermatopathology.
Consultation services are provided for difficult diagnostic problems. Consultation cases may be sent by a referring pathologist and directed to one of the pathologists who is an expert in the given area or directed more broadly to the subspecialty group. Cases are frequently shared and sometimes transferred between the pathologists, as deemed appropriate for the type of case or diagnostic problem encountered. Emphasis is placed on prompt and accurate results. Materials received are reviewed in conjunction with the clinical history provided, laboratory findings, radiographic findings (if applicable), and sending pathologist's report or letter. If additional special stains or studies are needed, the results are included in the final interpretive report. In some cases, electron microscopy and other special procedures are utilized as required.
A variety of ancillary studies are available (eg, cytochemistry, immunohistochemistry, immunofluorescence, electron microscopy, mass spectrometry, cytogenetics, and molecular genetics) to aid in establishing a diagnosis. These ancillary studies are often expensive and labor intensive and are most efficiently utilized and interpreted in the context of the morphologic features. The goal is to provide the highest possible level of diagnostic consultative service, while trying to balance optimal patient care with a cost-conscious approach to solving difficult diagnostic problems.
