Cystatin C is a protein of the cysteine protease inhibitor group that is mostly produced in nucleated cells. Its production is not affected by inflammatory or consumptive diseases. Cystatin C is exclusively glomerular filtered and reabsorbed by the proximal tubule epithelium. Thus, the value describes the performance of glomerular filtration of the kidney. It shows … Cystatin C
The thirst test (two-step test) is a diagnostic test designed to rule out diabetes insipidus. Diabetes insipidus is a congenital or acquired disease characterized by increased urine output (polyuria) and an increased feeling of thirst with increased drinking (polydipsia) The procedure Material needed Urine samples before, during and after the thirst test. Blood samples before, … Thirst Test (Two-Step Test)
Uric acid is a metabolic end product from purine metabolism, approximately 80% of which is excreted by the kidneys (urinary). The laboratory parameter belongs to the renal retention parameters. It is used to assess the performance of the kidneys. An increase indicates impaired kidney function, as the substance is retained in the body (retention). If … Uric Acid
Urea is a metabolic end product from protein and amino acid metabolism (protein metabolism) that is formed in the liver. The toxic ammonia produced in amino acid metabolism is converted into the nontoxic urea via the urea cycle in the mitochondria (power plants of the cells) of the liver. Urea is highly water-soluble and 90 … Urea: Function in the Body
Creatinine (creatinine) is a metabolic product that is excreted in the urine (urinary). The laboratory parameter belongs to the renal retention parameters. It is used to assess the performance of the kidneys. An increase indicates impaired kidney function, as the substance is retained in the body (retention). Creatinine is formed in muscle tissue from creatine. … Creatinine: Uses, Effects, Side Effects, Dosage, Interactions, Risks
Creatinine clearance is an examination method for determining the clearance function of the kidneys. This allows a relatively accurate determination of the glomerular filtration rate (GFR) and thus the assessment of kidney function.The term clearance refers to the removal of certain substances from the blood in a certain time.Creatinine is a metabolic product that is … Creatinine Clearance
