Nitrogen is mainly present in the human body as a constituent of proteins and nucleic acids. The catabolism of these substances form nitrogenous compounds known as non-protein. Among the various non-protein nitrogenous compounds known, uric acid and creatinine may be used as biomarkers of renal function in humans. Creatinine is derived from the nonenzymatic reaction of dehydration of creatine or phosphocreatine dephosphorylation during the process of muscle contraction; its concentration is used as a clinical marker to assess renal function. Uric acid is formed from the metabolism of purine bases, as a low soluble compound, deposition in the end joints or other soft tissues in a case generates known as gout. Thus, creatinine and uric acid are constantly measured in laboratory tests of urine. The methodologies used for the determination of these two compounds ranging from classical methods to the use of HPLC, electrophoresis and flow analysis, namely, little portable techniques and some high cost. Thus, the possibility of the use of microfluidic paper - based analytical devices (¼PAD) for the determination of creatinine and uric acid will be studied, it is a cheap, clean, fast, portable and can be used in remote locations to function evaluation method kidney.
