Urine urea measurement evaluates the body's protein intake and nitrogen balance.
More information
Urea is a low-molecular-weight substance that is freely infiltrated by the renal glomeruli. Most of it is excreted in the urine, although various amounts can be absorbed along the kidney. Urea is the primary 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 increased glomerular filtration rate, dietary protein intake, protein catabolism, and diuretics. Factors that reduce urea secretion in the urine include low protein intake in the diet and conditions that lead to low urine output (e.g., dehydration).
Important Note
Laboratory test results are the most critical parameter for diagnosing and monitoring all pathological conditions. Between 70 to 80% of diagnostic decisions are based on laboratory tests. Correctly interpreting 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 analyzed based on each case and family history, clinical findings, and the results of other laboratory tests and information. Your 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 contact your doctor to ensure you receive the best possible medical care.
