Test Overview
GEM 5000- ion-selevtive electrode, amperometric electrode, electrical conductivity, and optical absorbance
Determination of blood gases (pH, pCO2,PO2,SO2,HCO3), sodium, potassium, chloride, ionized calcium, glucose, lactate, hematocrit, and CO-Oximetry to aid in the diagnosis of a patient's acid/base status, electrolyte and metabolite balance, and oxygen delivery capacity
Analyte specific reference ranges are available the GEM 5000 test procedure located on the POC website: https://www.pathology.med.umich.edu/point-of-care
Reference ranges may change over time. Please refer to the original patient report when evaluating results.
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
•Specimens must be free of clots and fibrin strands.
Test Details
45 seconds
Specimen Requirements
Collect in heparinized syringe.
Samples must be tested within 15 minutes of draw time and within 5 minutes if measuring lactate. Expel air bubbles and thoroughly mix syringe samples for >30 seconds by repeatedly inverting and rolling syringe immediately after sample collection. Sample syringe must be capped to seal out air until sample is analyzed in order to maintain accurate pH and blood gas values (pO2, pCO2, O2Hgb).
