Urea nitrogen [Mass/Vol]
Urea nitrogen is a byproduct of protein metabolism, processed in the liver and excreted by the kidneys. It reflects protein turnover, hydration status, and renal function. Low levels might indicate under-eating protein or liver issues, while high levels can result from dehydration, high protein intake, intense training, or impaired kidney function. BUN is most useful when paired with creatinine to assess filtration efficiency and nitrogen balance.solve real problems with clean design and honest materials.
