Test Code

The Urea test estimates the concentration of urea, a nitrogen-containing waste product formed in the liver from protein breakdown and excreted by the kidneys.

Blood urea levels reflect how efficiently the kidneys are filtering waste from the bloodstream. Elevated urea levels may indicate impaired kidney function, dehydration, high protein intake, gastrointestinal bleeding, or heart failure, while low levels may be seen in liver disease, malnutrition, or overhydration. This test is commonly ordered along with creatinine as part of routine kidney function evaluation.
