List Analyzes – U
Uric acid excreted in urine reflects the intake of purines with food and the breakdown of endogenous purine nucleotides.
Uric acid is a product of the exchange of purine bases, which are part of complex proteins-nucleoproteins. Formed uric acid is secreted by the kidneys.
Urea excretion in urine is proportional to the protein content in the diet, as well as the metabolic rate of endogenous proteins.
Urea is the end product of protein metabolism in the body. It is removed from the body by glomerular filtration, 40-50% of it is reabsorbed by the tubular epithelium of the kidneys and is actively secreted by tubular cells.
Estriol is the main estrogen synthesized by the placenta during pregnancy. Unbound estriol passes through the placenta and enters the bloodstream of the pregnant woman, where it quickly turns into glucuronide and sulfate derivatives, which facilitates the process of its excretion.
