About Urea and electrolytes (blood)
What are urea and electrolytes?
Urea is a metabolic waste product excreted in the urine by the kidneys. Urea is used to transport nitrogen waste from proteins, which is produced as ammonia in the liver and combined with other elements such as oxygen, hydrogen and carbon to produce urea. Urea is transported through the blood to the kidneys, where it is excreted and used along with electrolytes such as sodium to control the amount of water lost in the urine. Abnormal blood urea and electrolyte levels are a common method of assessing overall kidney function.
Why take the test?
This test measures the concentration of urea, sodium and creatinine in the blood. It is typically used to monitor kidney function and diagnose kidney damage.
