What is an LFT?
Liver Function Test (LFT) is a simple blood test that checks how well your liver works. The liver is a vital organ. It helps your body digest food, store energy, and remove toxins. Because of this, doctors often use an LFT blood test to check your liver health. The test measures different chemicals and proteins in your blood. These results show if your liver is healthy or if there may be a problem.
Why is an LFT Done?
Doctors order an LFT for many reasons. Sometimes, they want to check your liver before starting certain medicines. Other times, they use it to watch for liver damage or disease. For example, an LFT can help find problems early, even before you feel sick. Early detection is important because it can prevent serious health issues.
