Urea is a waste product formed in the liver from protein metabolism and is excreted by the kidneys. It is commonly measured alongside creatinine to assess renal function and fluid balance. Urea levels can help in the evaluation of kidney function and may assist in distinguishing prerenal, renal, and postrenal causes of kidney impairment.

The findings related to these particular clinical tests are a general guide and do not cover every possible scenario, this is because every patient is unique and these results only have true clinical significance when combined with the patient’s full medical history, a physical exam, and other diagnostic findings.
