The liver plays a critical role in maintaining overall health by filtering toxins, producing bile, and regulating nutrients. When your liver is not functioning well, it can lead to a range of health issues
What Is a Liver Function Test (LFT)?
A Liver Function Test (LFT) is a series of blood tests used to measure enzymes, proteins, and other substances produced by the liver. It helps your doctor assess how well your liver is functioning and detect potential liver problems, such as hepatitis, fatty liver disease, or cirrhosis. LFTs can also monitor ongoing liver conditions and the effects of medications that may impact liver health.
Why Is a Liver Function Test Important?
The liver is vital for many body functions, including detoxifying harmful substances and regulating blood sugar levels. If your liver isn’t working properly, it can affect your entire body. The LFT helps detect problems early, even if there are no visible symptoms. Early detection allows for better management of liver disease and can prevent serious complications, such as liver failure.
What Does a Liver Function Test Measure?
A liver function test checks for several key markers that indicate how well your liver is functioning, such as:
- Alanine transaminase (ALT) and Aspartate transaminase (AST): High levels can indicate liver damage.
- Alkaline phosphatase (ALP): High levels can signal bile duct issues or bone disease.
- Bilirubin: High levels can indicate jaundice or other liver problems.
- Albumin: Low levels can indicate poor liver function.
These tests provide your doctor with crucial information about your liver health.
When Should You Get a Liver Function Test?
Your doctor may recommend an LFT if you are showing symptoms of liver disease, such as jaundice (yellowing of the skin), fatigue, abdominal pain, or dark urine. You may also need an LFT if you have a history of liver disease, alcohol abuse, or are taking medications that affect liver function. Regular screening is important for early detection and prevention of more serious conditions.
How Is a Liver Function Test Done?
A liver function test is a simple blood test. A healthcare provider will take a small sample of your blood, usually from a vein in your arm. The process is quick, and results are typically available within a few days. Based on the results, your doctor will guide you on the next steps, whether it’s further tests, lifestyle changes, or treatments.
A Liver Function Test is a simple yet essential tool to assess the health of your liver. Regular monitoring of liver health is crucial for early detection of liver issues, leading to timely treatment and prevention of severe complications. Don’t ignore symptoms or delay testing, as your liver’s health is vital for your overall well-being.
