Introduction to liver test
A delivery test, also known as a liver function test (LFT), is a blood test used to assess how well your liver works and to investigate liver damage or illness. The liver plays an important role in treating nutrients, producing bile for digestion and detecting harmful substances from the body. The liver test measures the levels of different enzymes, proteins and substances in your bloodstream either produced by the liver or when liver cells are damaged.
How Deliver Test works:
Collection of blood test: A health care provider takes a small sample of blood, usually from a vein in hand.
Laboratory analysis: Blood sample is sent to a laboratory, where it is tested for several main leverenzymes and proteins.
Results: Test results may indicate whether the liver works normally or whether there are signs of liver damage or illness.
Main component measured in a delivery test:
Alaninaminotransferase (alt): An enzyme is found mainly in the liver. High levels of everything can indicate liver damage.
Aspartataminotransferase (AST): An enzyme found in the liver, heart and muscles. The elevated AST level may indicate liver damage, although it may also be raised due to other problems.
Alkaline phosphate (Alp): an enzyme related to bile duct. High levels can indicate obstacles to bile duct or liver disease.
Bilirubin: A substance is produced when the liver breaks red blood cells. Elevated bilirubin can cause jaundice (yellow of skin and eyes) and indicate liver dysfunction.
Albumin: A protein produced by the liver. The low level of albumin may indicate liver disease or poor liver function.
Importance of liver test
Liver tests are important for assessing your liver health and detecting potential liver problems. These tests measure some enzymes, proteins and levels of substances in your blood that may indicate how well your liver is doing. Here are some reasons why liver tests are important:
Detection of liver diseases: Deliver tests can help identify liver conditions such as hepatitis, cirrhosis, oily liver disease or liver cancer. Early identification is important for effective treatment and management.
Liver function monitoring: The liver plays an important role in detoxifying the body, producing bile and metabolizing nutrients. A delivery test can inform doctors about how well your liver is doing, and it is affected by diseases or toxins.
Assessing the effect of the drug: some medicines, especially painkillers, cholesterol medicines and antibiotics, can damage the liver over time. Ordinary liver tests can monitor any liver damage signal due to medication.
Evaluation of risk factors: If you have risk factors such as the use of heavy alcohol, obesity, diabetes or family history with liver disease, liver tests can help assess the risk and capture problems quickly.
Guidance of the treatment decision: If you have liver conditions, regular testing allows health care professionals to monitor liver function changes and adjust treatment schemes accordingly.
