About this test

What is this test for?

Abnormal urea levels may indicate impaired kidney function, dehydration, excessive protein breakdown, or liver dysfunction. Results are often interpreted alongside creatinine and electrolyte measurements to provide a fuller picture of renal health.


What does this test measure?

Urea is a waste product formed in the liver during the breakdown of proteins and eliminated by the kidneys. The test measures the concentration of urea in the bloodstream, reflecting how effectively the kidneys are filtering and excreting waste.


When is this test recommended?

Urea measurement is commonly requested when assessing kidney function, investigating dehydration, monitoring chronic kidney disease, or evaluating patients with symptoms such as fatigue, swelling, or changes in urination. It is also routinely included in broader renal or metabolic panels.
