The liver panel measures enzymes, proteins, and substances that are produced, processed or eliminated by the liver and are affected by liver injury. Early detection is essential in order to minimize damage and preserve liver function. A significant amount of liver damage may be present before symptoms such as jaundice, dark urine, light-colored stools, itching (pruritus), nausea, fatigue, diarrhea, and unexplained weight loss or gain emerge. Alcohol, drugs, some herbal supplements, and toxins can also pose a threat. Bile, a fluid produced by the liver, is transported through ducts directly to the small intestine to help digest fats or to the gallbladder to be stored and concentrated for later use.Ī variety of diseases and infections can cause acute or chronic damage to the liver, causing inflammation (hepatitis), scarring (cirrhosis), bile duct obstructions, liver tumors, and liver dysfunction. It produces blood clotting factors, proteins, and enzymes, helps maintain hormone balances, and stores vitamins and minerals. The liver metabolizes and detoxifies drugs and substances that are harmful to the body. The liver is one of the largest organs in the body and is located in the upper right-hand part of the abdomen and behind the lower ribs. Substances measured in liver function testingĪ liver panel is a group of tests that are performed together to detect, evaluate, and monitor liver disease or damage. Only a physician who knows all the aspects of a specific case can reliably make a diagnosis. People reading this page should keep in mind that abnormalities within liver tests don’t necessarily point to specific diseases. Diagnosis of hepatitis C usually also involves antibody tests or PCR tests. It’s important to remember that diagnosis of liver disease depends on a combination of patient history, physical examination, laboratory testing, biopsy and sometimes imaging studies such as ultrasound scans. They can show if there is damage to liver cells or a blockage near the liver. Liver function blood test examines the proteins, enzymes, that indicate how well your liver is working. The liver helps to process the body’s nutrients, manufactures bile to help digest fats, produces many important proteins such as blood clotting factors, and breaks down potentially toxic substances into harmless ones that the body can use or excrete. Among them, the liver processes drugs and alcohol, filters toxic chemicals, stores vitamins and minerals, and makes bile, proteins and enzymes. The liver is a vital organ that is involved in more than 500 functions. The liver is a large organ that is located in the upper right-hand side of the abdominal area just beneath the rib cage. So a more correct term for a liver test would actually be a liver dysfunction test. This gives a gauge of possible damage to liver cells. A liver function test (LFT) is also very useful to see if there is active damage in the liver (hepatitis) or sluggish bile flow (cholestasis). Liver function tests measure the amount of particular chemicals in the blood. Liver function test examines the levels of a number of proteins, enzymes and other substances that are either produced by liver cells or released into the blood when liver cells are damaged. Liver test gives an indication of whether the liver is functioning properly. Liver function test (also called LFT or liver panel test) is a blood test that can provide information about how your liver is working.
