The Neuropathology service is led by Dr. Brent Harris and offers full diagnostic laboratory services to support the MedStar Health network.  Institutional and consult surgical pathology services are available for CNS/PNS tumors and other lesions including coordination for advanced molecular testing.

In addition, MedStar Georgetown University Hospital functions as a full muscle and nerve diagnostic laboratory. Muscle biopsy helps to identify unexplained muscle weakness, fatigue and elevated CPK, and distinguish between dystrophies, metabolic myopathies, inflammatory myopathies, and neurogenic myopathies. Nerve biopsies can assist with diagnosis of CIDP, vasculitis, amyloidosis, and other neuropathies. Muscle and nerve biopsy tissues can be sent to MedStar Georgetown using our easy-to-use kits that are sent to you free of cost. We accept all of MedStar Georgetown biopsies as well as consults from around the country.

Services Include:

  • Clinical evaluation
  • Tissue preparation
  • Pathological interpretation including advanced histochemistry, nerve teasing, and electron microscopy

To request a muscle/nerve biopsy kit, contact the neuropathology lab at least 48 hours before the muscle biopsy is collected at (202) 687-4282. Biopsies are accepted Monday through Friday. Turnaround time is 7 to 10 days.

Additional neuropathology services such as CNS biopsy, autopsy consultations, and brain biobanking are available from the Georgetown Brain Bank. For more information about diagnostic services provided please contact the Department of Pathology at (202) 784-3614
