The Johns Hopkins Neuromuscular Pathology Laboratory

The Johns Hopkins Department of Neurology offers comprehensive services for the evaluation of nerve and muscle disease, including:

  • Clinical evaluation
  • Nerve and muscle biopsy
  • Tissue preparation
  • Pathological interpretation

Nerve and muscle biopsies are performed by specially trained physicians, usually as an outpatient procedure. Nerve and muscle tissues are prepared by the clinical specialty laboratories in the Department of Neurology. The results of pathological studies are interpreted by designated neuromuscular specialists in the department.

Outside nerve and muscle biopsy tissues may be sent to the Neuromuscular Pathology Laboratory for staining and interpretation; instructions for nerve and muscle processing are available on this web site. Specimens that have been obtained and stained elsewhere may be referred for neuropathological consultation (second opinion).

To refer a patient for clinical evaluation or for biopsy and pathological consultation services, please call 410-614-4278.
