Uric acid dosage

Uric acid is a final metabolite of the breakdown of purines, nitrogenous bases present in nucleic acids (DNA, RNA). In mammals, it is primarily excreted in the urine. Its excessive accumulation in the body can lead to various pathologies, including gout, uric arthritis, or kidney disorders, in both humans and animals.

In the field of animal health, uric acid is a key metabolic indicator, used to monitor the physiological state of animals, assess the effects of certain high-protein diets or detect possible metabolic abnormalities.

In the food industry, uric acid can be used as a marker of spoilage in certain animal products, or to detect the presence of animal flours in nutritional formulations.

Why measure uric acid?

Uric acid measurement is essential in several industrial and regulatory contexts:

• Animal health monitoring: metabolic monitoring, renal disorders, hyperuricemia;
• Quality control of animal feed supplements: verification of non-protein nitrogen or purine levels;
• Detection of contamination or fraud in powders of animal origin or processed products;
• Assessment of renal and hepatic functions in toxicology or comparative nutrition studies.

Available analytical methods

At YesWeLab, uric acid measurement is performed using high-performance liquid chromatography (HPLC) or chromatography coupled with mass spectrometry (LC-MS) methods, allowing precise detection, even at trace levels, in complex matrices.

These methods offer excellent sensitivity, high specificity and allow the reliable quantification of uric acid, even in the presence of interfering compounds.

Commonly analyzed matrices

Analyses are performed on a wide range of matrices, including:

• Animal urine (veterinary, research, zootechnics);
• Food supplements for pets or livestock;
• Animal powders or hydrolysates used as nutritional ingredients;
• Processed foods of animal origin, for quality control or detection of alterations.

Further analyses recommended

For a complete evaluation of the analyzed samples, the uric acid dosage can be combined with other services available in the YesWeLab catalog, including:

• Creatinine dosage : for the joint assessment of renal function;
• Purine and pyrimidine assay: to monitor metabolic precursors;
• Analysis of free amino acids : indicators of protein quality and nitrogen metabolism;
• Total nitrogen and non-protein nitrogen profile : to characterize animal or nutritional matrices.
