About the product
UA2 (Uric Acid ver.2) is an in vitro diagnostic reagent from Roche Diagnostics for the cobas c and COBAS INTEGRA systems. According to Roche, the test is used for the quantitative determination of uric acid in human serum, plasma and urine.
The reagent is intended for laboratory measurement only. Interpretation of the result depends on the physician’s clinical assessment. The product is part of the Roche Diagnostics test kit range supplied by Tilia Medical.
Measured parameter and clinical significance
Uric acid is a waste product formed when the body breaks down purines. According to MedlinePlus, a blood uric acid measurement is used to help diagnose gout, often together with synovial fluid analysis. Monitoring levels in people undergoing cancer chemotherapy or certain other cancer treatments is another reason for the test.
A urine measurement helps assess whether high uric acid contributes to kidney stones. It is also used to monitor kidney stone risk in people with gout. MedlinePlus notes that the urine sample may be collected over 24 hours.
According to MedlinePlus, the blood sample is drawn from a vein in the arm, and the procedure usually takes less than five minutes. For the urine test, all urine passed over 24 hours is collected and kept cold as instructed. Roche’s reagent covers both blood-derived serum and plasma samples and urine.
