Urine urea measurement is used to evaluate protein intake and nitrogen balance in the body.
More information
Urea is a low molecular weight substance, which is freely infiltrated by the renal glomeruli and most is excreted in the urine, although various amounts can be absorbed along the kidney. Urea is the major end product of protein metabolism. Under normal conditions, about 50% of total soluble urine and 90 to 95% of total nitrogen excretion are urea.
Factors that increase urea secretion include increases in glomerular filtration rate, increased dietary protein intake, increased protein catabolism, and increased diuretics. Factors that reduce the secretion of urea in the urine include low protein intake in the diet and conditions that lead to low urine output (eg dehydration).
Important Note
Laboratory test results are the most important parameter for the diagnosis and monitoring of all pathological conditions. 70%-80% of diagnostic decisions are based on laboratory tests. Correct interpretation of laboratory results allows a doctor to distinguish "healthy" from "diseased".
Laboratory test results should not be interpreted from the numerical result of a single analysis. Test results should be interpreted in relation to each individual case and family history, clinical findings and the results of other laboratory tests and information. Your personal physician should explain the importance of your test results.
At Diagnostiki Athinon we answer any questions you may have about the test you perform in our laboratory and we contact your doctor to get the best possible medical care.
