Testing Algorithm
When this test is ordered, 1 or more of the listed reflex tests will be performed and charged separately. The reviewing neuromuscular pathologist will determine the need for additional testing.
For all consultations, ancillary testing necessary to determine a diagnosis is ordered at the discretion of the Mayo Clinic neuromuscular pathologist. An interpretation will be provided within a formal pathology report.
Slides and blocks sent for consultation: 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 repeat testing at an additional charge at the discretion of the reviewing Mayo Clinic neuromuscular pathologist.
Special Instructions
Method Name
The evaluation includes an evaluation of provided or performed enzyme histochemical stains or immunostains; other tests can be performed as indicated and will be charged separately.
Reporting Name
Muscle Bx Consultation, Slide/BlockSpecimen Type
TissueFor all specimens, patient history and requests should be clearly labeled with correct patient identifiers and pathology accession/case number. Collection date and patient date of birth are required. All specimens must be labeled with specimen type. The name and phone number of the ordering physician and a brief history are essential to achieve a consultation fully relevant to the ordering physician's needs. The Muscle Histochemistry Patient Information sheet should accompany all specimens. Failure to provide this information may delay the specimen processing significantly.
Biopsies from different sites require separate orders and separate specimen vials.
Specimen Type: Muscle biopsy slides and/or blocks
Collection Instructions: Submit all stains performed on the case. If electron microscopy (EM) has been performed, include EM images (either on a CD or as prints).
Additional Information:
1. A brief explanatory note or consultative letter is necessary.
2. This test is not intended for use with tissue that still needs to be processed.
Forms:
1. Muscle Histochemistry Patient Information Sheet (Supply T361) in Special Instructions
2. If not ordering electronically, complete, print, and send the following form with the specimen:
