Diazyme's Potassium Assay has an outstanding linearity range from 2.0 mmol/L – 8.0 mmol/L. Diazyme's Potassium Assay offers excellent precision CV% of
<2%. A comparison study showed that the assay has good correlation with existing ISE method's with a correlation coefficient value of 0.98, slope of 1.07 and y
intercept of -0.30. The assay shows virtually no affect by the following interfering substances at indicated concentrations: Na+ 150mM, NH4+ 0.5 mM, Ca2+ 7.5
mM, Pi 2.0 mM, ascorbic acid 10.0 mM, Zn2+ 0.5 mM, Fe3+ 0.5 mM, Cu2+ 0.5 mM, triglycerides 1000 mg/dL, hemoglobin 500 mg/dL, conjugated bilirubin 20 mg/
dL and unconjugated bilirubin 15 mg/dL.
