Intended Use

The URCA (Uric acid) method used on the Dimension® clinical chemistry system is an in vitro diagnostic test intended for the quantitative determination of uric acid in serum, plasma and urine. This product is suitable for use on the Siemens Dimension® analyzers.


Clinical Significance

Uric acid is useful in the diagnosis and treatment of several renal and metabolic disorders including kidney disease, leukemia, psoriasis and starvation.

Elevated levels of uric acid in the blood indicate that the body is breaking down cells too quickly or that the body is not getting rid of uric acid quick enough. High levels can result in inflammation of joints, gout and kidney stones.

Lower than normal levels or uric acid in the blood are rare and not of clinical significance. Decreased values however are associated with some kinds of liver and kidney disease.


Principle


Uric Acid, which absorbs light at 293 nm is converted by uricase to allantoin, which is nonabsorbing at 293 nm. The change in absorbance at 293 nm due to the disappearance of uric acid is indirectly proportional to the concentration of uric acid in the sample and is measured using a bichromatic (293,700 nm) endpoint technique.
