Lab Receiving Hours

Neuromuscular Pathology Receiving Hours

Monday – Friday, 7:00 am – 2:30 pm

The Neuromuscular Pathology laboratory has been providing services for over 40 years by experienced technical and professional staff. All specimens are evaluated by a board-certified neuromuscular pathologist to determine the most appropriate tests for each patient, and a final clinical report is issued with the pathologists’ interpretation of the patient’s neuromuscular disease.

The surgical team at Hennepin Healthcare now offers same-day consults and muscle and nerve biopsies whenever possible. If you are a provider looking to refer a patient to Hennepin Healthcare for a muscle or nerve biopsy, please contact our lab directly at 612-873-2175.

Required paperwork for a biopsy referral:

*Please make sure that the referring provider and the specific muscle or nerve that should be biopsied is clearly indicated!

Our neuromuscular pathologists are board-certified in Clinical Neuromuscular Pathology by the United Council for Neurologic Subspecialties. We evaluate each case thoroughly and strive to incorporate the clinical history, documented exam, serological testing and additional relevant testing with neuromuscular pathology abnormalities to achieve a diagnosis as well as possible differential diagnosis. Additional testing such as immunohistochemistry will be added at the discretion of our neuromuscular pathologists to help increase the yield and specificity of the final interpretation.  Personal consultation is available to clinicians to answer questions about the testing process and patient’s results. Detailed instructions for handling muscle and nerve tissue samples as well as proper fixatives can be requested by calling the lab at 612-873-2175. Our Specimen Preparation Instructions are also available for download.

The results of each of these studies are integrated with the clinical presentation to provide a final interpretation of the patient's neuromuscular disease. Specimens received are processed immediately and a preliminary report is available by phone in 3 days. The final report is typically ready within ten days.
