Functional samples of the kidney

Kidney The main excretory (excretory) organ of the human body is that which filters the blood rich in the products of metabolism (decomposition) of the body and releases harmful substances. Blood filtration is urine that accumulates in the bladder and is excreted out of the urethra.

Kidneys The most important Physiological Role Homeostasis There is regulation: The kidneys participate in the maintenance of osmotically active substances (osmoregulation), their volume (volume regulation), electrolyte and acid-base balance in plasma and intracellular fluid, excrete nitrogen metabolism products, participate in the metabolism of proteins, carbohydrates, lipids, organelles and lipids. In regulation.

Consequently, the assessment of the concentration of substances in the blood, which are excreted by the kidneys in the urine, allows the assessment of its functional state.

The functional profile of the kidney include of 7 main parameters (Click on a specific product for more information on each parameter):

Creatinine - The end product of protein metabolism, which is produced in the liver, circulates in the blood and is excreted by the kidneys. Its abundance is accompanied by acute renal failure and chronic kidney disease.

Urea - The final product of protein breakdown, which is produced from ammonia in the liver and is involved in the concentration of urine. Increases in chronic glomerulonephritis, pyelonephritis, tuberculosis, chronic kidney disease.

Uric acid -   The metabolic product of purine bases (included in nucleoproteins) excreted by the kidneys. Found in extracellular fluid in the form of sodium salts.

Calcium, Sodium, Phosphorus, Potassium - The basic parameters of the body's electrolyte homeostasis, in the metabolism of which the kidneys play an important role. Complex determination and evaluation of their concentration in the blood gives us information about the functional state of the kidneys.
