Ammonia, NH3

As of March 1, 2016, Spectrum Health Laboratory, Grand Rapids, will no longer draw or send a courier for outpatient Ammonia testing (#8074). If outpatient Ammonia testing is needed, the patient must be collected at the 35 Michigan Draw Site. If outpatient Ammonia testing is needed and the patient cannot be drawn at the 35 Michigan Draw Site, approval must be obtained from Dr. David Alter or the Clinical Pathologist on-call, prior to ordering the test.

There will be no changes to inpatient collection. Note: Inpatients are patients who have been admitted to a hospital in the Medical Center (HDVCH, Butterworth, and Meijer Heart Center) or Blodgett Hospital.

Any questions concerning these changes may be directed to Dr. David Alter in the Pathology Department.
