What This Value Measures
Urea is produced during the breakdown of protein and is excreted by the kidneys. This value provides information about kidney function and fluid balance.
Elevated Value
An elevated value may indicate impaired kidney function, dehydration, or a high-protein diet.
Low Value
A decreased value may occur with a low-protein diet or liver disease.
Reference ranges are typical guide values for adults and vary depending on the laboratory, measurement method, age and sex — always compare with the range stated on your own report. A value outside the range does not automatically mean an illness, and a value within the range does not rule one out. The trend and overall picture are usually more informative than a single value. The doctor's assessment is always decisive.
