A LFT blood test, also known as a liver function test, is a common blood test that helps doctors assess the health and function of your liver. The test measures the levels of certain enzymes and proteins in your blood that are produced by the liver. These levels can indicate whether your liver is damaged, inflamed, or not functioning properly.
Liver function tests are often used to:
- Diagnose liver disease: LFTs can help identify different types of liver diseases, such as hepatitis, cirrhosis, and fatty liver disease.
- Monitor liver disease: LFTs can help track the progression of liver disease and monitor the effectiveness of treatment.
- Screen for liver disease: LFTs may be used to screen for liver disease in people who have risk factors, such as heavy alcohol consumption or exposure to certain toxins.
- Evaluate the effects of medications: LFTs can help assess the potential side effects of certain medications on the liver.
LFTs are a safe and painless procedure. A small sample of blood is drawn from a vein in your arm, usually at a doctor's office or a lab. The results are typically available within a few days.
Example of LFT results:
If your LFT results show elevated levels of certain enzymes or proteins, it may indicate that your liver is not functioning properly. However, it's important to remember that LFT results should always be interpreted in the context of your individual medical history, symptoms, and other factors.
Note: While the acronym LFT commonly stands for "Liver Function Tests," it is important to remember that these tests don't measure every aspect of liver function. They primarily assess liver function by measuring certain substances that the liver produces or breaks down.
