Liver Function Test (LFT) is a panel of blood tests which help in detecting any damage or inflammation to your liver. There are a number of disorders that may be diagnosed using the liver function tests. There are a few diseases which need liver profiles to study progress and improvement from an ongoing medical treatment.
This is a very simple test and requires no prior preparation. This test requires a small amount of blood that is collected from your arms through a venipuncture. A healthcare provider will tie your arm with an elastic band that allows blood to accumulate in one of the veins that gets swelled up. A needle is then used to draw out the required amount of blood. The punctured area is then covered with a cotton pad. The collected sample is then tested under laboratory conditions.
