DIRECTOR: Vivian E. Shih, M.D.
LOCATION - MGH EAST, 149 6310, (6-West)

The Neurochemistry Laboratory is located at MGH East, Building 149, Charlestown, 6th floor, West, and operates Monday through Friday from 8:30 am to 5pm. Specimens are delivered to the laboratory from the Main Campus via the Phlebotomy/Transport Service. The last transportation van of the day leaves the Main Campus at approximately 3 pm. When the laboratory is closed, or when transportation is not available, specimens should be stored in a refrigerator and delivered as soon as possible.

The tests offered by this laboratory are primarily for the detection of hereditary metabolic disorders of amino acids, organic acids and sugars. Quantitative determinations of plasma and urine amino acids are available for monitoring patients on dietary treatment, hyperalimentation and other medications. Certain drugs may interfere with testing; examples are antibiotics and dyes used for radiographical studies. Thus, medication and clinical information should be included on the requisition for proper interpretation of results, and to help determine which additional tests may be appropriate.

Criteria for Refusal of Specimens - The laboratory reserves the right to refuse specimens considered unsuitable (e.g., urine specimens contaminated with fecal material, badly hemolyzed blood).

Results
Laboratory personnel will call the requesting area or physician when a metabolic disorder which requires prompt attention is suspected. Upon completion of testing, written reports are mailed to the requesting area and ordering physician, so please clearly indicate the mailing address for all reports.
