or the colorimetric determination of potassium in human serum and plasma on TC Matrix analyzers.
Number of Tests:
510 tests
Testing Procedure:
Automated
Wavelength:
510 nm
Expected Values:
3.4 – 5.3 mEq/L
It is recommended that each laboratory establish its own range of expected values.
Linearity:
2 – 7 mEq/L
Reagent Deterioration :
Do not use if: (1) The reagent is very cloudy; (2)T he reagent fails to achieve assigned
value on fresh control serum.
Limitations of Procedure:
Turbid or icteric samples produce falsely elevated results.
Bilirubin above 40 mgdL and Urea Nitrogen above 80 mgdL will produce elevated
results.
Hemolyzed sera produce elevated results.
Sera containing high levels of ammonia should be avoided.
