GEM 5000- ion-selective electrode
The test is performed in the hemodialysis unit by point of care operators. Potassium measurements are used to monitor electrolyte balance in the diagnosis and treatment of disease conditions characterized by low or high blood potassium levels. 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.
Hemolyzed specimens will give falsely high potassium results.
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.
