GEM 5000- ion-selective electrode, amperometric electrode, electrical conductivity, and optical absorbance
This test is performed in the hemodialysis unit by point of care operators. Determination of whole blood sodium, potassium, ionized calcium, pH and HCO3 to aid in the diagnosis of a patient's acid/base status, electrolyte and metabolite balance. During the hemodialysis procedure, serum potassium levels are monitored to reduce the risk of cardiovascular events.
Analyte specific reference ranges are available in the Gem 5000 test procedure located on the POC website: https://www.pathology.med.umich.edu/point-of-care.
Specimens must be free of clots and fibrin strands.
Collect in heparinized syringe.
Samples must be tested within 15 minutes of draw time. Sample must be tested immediately after exposing the sample to room air.
