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, and 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 agri-food sector, uric acid can be used as a spoilage marker in certain products of animal origin, or to detect the presence of animal meal in nutritional formulations.

Why measure uric acid levels?

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

• Animal health monitoring: metabolic monitoring, kidney 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;
• Evaluation of renal and hepatic function in toxicology or comparative nutrition studies.

Available analytical methods

At YesWeLab, uric acid analysis is carried out using high-performance liquid chromatography (HPLC) or chromatography coupled with mass spectrometry (LC-MS) methods, allowing for precise detection, even in trace amounts, in complex matrices.

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

Commonly analyzed matrices

The analyses are performed on a wide range of matrices, including:

• Animal urine (veterinary, research, animal husbandry);
• Dietary 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, uric acid testing can be combined with other services available in the YesWeLab catalog, including:

• Creatinine measurement : for the joint assessment of renal function;
• Assay of purines and pyrimidines: 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.
