Urea and electrolytes provide a baseline assay of water and electrolyte homeostasis, and renal function, from the blood.


Urea, like creatinine, is a waste product of normal bodily function - its level in the blood is controlled entirely by the kidneys. Rising levels of Urea that are detected in your pathology results may indicate kidney disease or damage, although small rises may also be a sign of dehydration. Low levels are of no concern.
