WHAT IS BEING TESTED?
Liver Function Tests is a group of tests that are conducted together to detect, investigate, and monitor liver disease and damage. The liver is one of the largest and important organs in the body and is situated in the upper right-hand part of the abdomen and behind the lower ribs. The liver detoxifies drugs and substances that are injurious to the body. It produces blood clotting factors, proteins, and enzymes and helps to maintain the hormone balances, and stores vitamin and minerals. The Bile is a fluid secreted by the liver and is transported through ducts to the small intestine and helps in digesting the fats or to the gallbladder to be stored and concentrated for later use.
