It is notable by such advantages as simple and fast performance, the absence of toxic compounds, high reproducibility and repeatability. The biosensor based on the method developed was applied for urea measurement in samples of blood serum. It was shown that the biosensor could surely distinguish healthy people from people with renal dysfunction. Good results reproducibility was proved at urea determination in real samples of blood serum (RSD = 10%). For these reasons, the biosensors based on enzyme adsorption are more suitable for standardization and production than those based on conventional methods of immobilization.
