The liver is responsible for a number of important tasks that contribute to an individual’s general health and well-being. It also controls the coagulation of blood, the metabolism of lipids and proteins, and the removal of toxins from the blood. Inflammation, as well as damage to the liver, can be brought on by a number of factors, including viral infections, medicines, hereditary abnormalities, high alcohol intake, as well as obesity. Ongoing injury to the liver can result in the development of scar tissue, which, if left untreated, can evolve into a life-threatening condition known as cirrhosis.

Around the world, liver disease is responsible for almost 2 million deaths each year. On the other hand, liver disease in its early stages does not usually present with symptoms.

The liver function tests (LFTs), also known as hepatic function tests, a liver panel, or liver enzymes, are blood tests that assess a number of enzymes and proteins in the liver. Other names for these tests include liver enzymes and a liver panel. You can also check about the LFT test price in Delhi online or by visiting the labs near you.

Purpose of LFT Test 

In a test of liver function, a number of substances that are relevant to the functioning of the liver are measured.

What exactly does it entail if the outcome is not typical?

Because interpreting the findings of a test of liver function can be difficult, it is recommended that you discuss the results with your healthcare provider. They will be able to tell you what is typical for you as well as how the findings connect to the rest of your signs and symptoms.

These tests are not without flaws. It is possible to get abnormal readings if you suffer from other health disorders that are unrelated to the liver. The readings could be normal for some persons, even when they have extremely severe liver disease. You will find a small variation in the LFT test price in Delhi from lab to lab.
