Urea is a waste product generated in the liver when the body metabolizes proteins. It is subsequently transported through the bloodstream to the kidneys, where it is filtered out and excreted in urine. Measuring urea in the blood, often referred to as blood urea nitrogen (BUN) in some regions, provides an indicator of kidney function and overall metabolic health. This biomarker aids in assessing the kidneys' capacity to remove waste products from the body effectively.
