The liver normally converts ammonia into urea, which is then eliminated in urine. Ammonia levels in the blood rise when the liver is not able to convert ammonia to urea. This may be caused by cirrhosis or severe hepatitis. For this test, a blood sample may be taken from either a vein or an artery. Why It Is Done. An ammonia test is done to:

The throw-out bearing is at the center of the clutch operation. When the clutch pedal is depressed the throw-out bearing moves toward the flywheel, pushing the pressure plate spring force.
