Uric acid is an end product of purine nucleotides metabolism and is cleared by glomerular filtration in the kidney. High level of uric acid in serum can lead to gout. Lack of urate oxidase can lead to the accumulation of uric acid in blood. Among persons with high cardiovascular risk, including those with diabetes, hypertension and congestion heart failure, serum urate level is closely associated with cardiovascular morbidity and mortality.

The Uric Acid Colorimetric/Fluorometric Assay Kit provides a simple and convenient way for detection of uric acid in various biological samples such as serum and urine based on colorimetric and fluorometric method. The assay can be performed without pretreatment of samples and measure uric acid level using colorimetric (at λ = 570 nm) or fluorometric (at Ex/Em = 535/587 nm) methods.
