Muscle Biopsy Consultation Kit Instructions
Muscle biopsies are performed in the evaluation of patients with neuromuscular or metabolic disease.
These specimens require highly-specialized tissue handling and staining procedures and interpretation by a neuromuscular pathologist. A comprehensive panel of enzyme histochemistry and special stains is performed on all specimens.
The best value for the patient is achieved when the treating physician provides pertinent clinical information, the surgeon removes an adequate specimen, and the local pathology laboratory packs the specimen properly and ships it promptly. Our Muscle Biopsy Consultation Kit provides the necessary materials to ensure specimen integrity during shipment to our laboratories.
Muscle Biopsy Consultation Kit:
Overview
Muscle biopsies are performed in the evaluation of patients with neuromuscular or metabolic disease. The procedure is requested by the treating physician, usually a neurologist or rheumatologist, and performed by a surgeon.
These specimens require highly-specialized tissue handling and staining procedures and interpretation by a neuromuscular pathologist. A comprehensive panel of enzyme histochemistry and special stains is performed on all specimens. Additional studies, including electron microscopy and immunohistochemistry for dystrophy-associated antigens, will be performed at the discretion of the neuromuscular pathologist based upon the light microscopic findings and clinical information provided.
The best value for the patient is achieved when the treating physician provides pertinent clinical information, the surgeon removes an adequate specimen, and the local pathology laboratory packs the specimen properly and ships it promptly.
Peripheral nerve biopsies are often performed at the time of muscle biopsy. Nerve biopsies have different handling requirements; see our Nerve Biopsy Consultation Kit Instructions for details.
Muscle Biopsy Consultation Kit:
Requisition
Prior to requesting a biopsy, the treating physician should obtain and complete a Muscle / Nerve Surgical Requisition. Fill the form out completely and provide it to the surgeon prior to the date of surgery.

1. Wrap the tissue in a saline-moistened Telfa pad, and place in a screw cap container.

2. Label all specimen parts with two of three patient identifiers:
- Patient name
- Date of birth
- Social security number
3. Place specimen container(s) in sealable plastic bag with absorbent pad.

4. Place the bagged container with the specimen in the Styrofoam shipping container with sufficient wet ice or cold packs to keep specimen at 4-8ËšC for 24-48 hours.

5. Place the Styrofoam container into the green shipping box.

6. Before sealing the box for shipment, include the completed requisition on top of the Styrofoam container.
7. Affix the provided UPS label to the green shipping box.
The specimen should be shipped Next Day Air to:
