For the quantitative determination of uric acid in serum.
Number of Tests:
240 tests
20 x 12 mL
Testing Procedure:
Manual
Reconstituted Stability:
30 days at 2 – 8°C
Wavelength:
520 nm
Expected Values:
1.5 – 7.0 mg/dL
It is recommended that each laboratory establish its own range of expected values.
Linearity:
25 mg/dL
Reagent Deterioration:
The reagent should be discarded if: (1) Turbidity has occurred; (2) Moisture has
penetrated the vial and caking has occurred. The reagent blank has an absorbance of
0.40 or greater at 520 nm.
Note: A slight pink color is normal.
Limitations of Procedure:
Bilirubin and ascorbic acid can result in falsely depressed uric acid levels.
Lipemic samples may cause falsely elevated uric acid levels.
Collection tubes containing formaldehyde as a preservative must be avoided.
