Magnesium reagent is used for the quantitative determination of magnesium in serum.
Number of tests:
100 tests
Testing Procedure:
Manual
Wavelength:
530 nm
Linearity:
4.0 mEq/L (4.86 mg/dL)
Expected Values:
Adults: 1.3‐2.5 mEq/L
Reagent Deterioration:
Failure to achieve assayed values on freshly prepared control sera would indicate
deterioration.
Working reagent becomes visibly turbid.
Limitations of Procedure:
Plasma collected with anticoagulants such as EDTA, citrate and oxalate must not be used.
A number of drugs and substances affect the concentration of magnesium.
