What is a Liver Function Test (LFT)?
A Liver Function Test (LFT) is a group of blood tests that measure different enzymes, proteins, and substances produced by the liver. These measurements help assess how well your liver is working and if there is any damage or inflammation.
The test typically includes measurements of:
- Alanine transaminase (ALT)
- Aspartate transaminase (AST)
- Alkaline phosphatase (ALP)
- Bilirubin (total and direct)
- Albumin
- Total protein
Doctors often recommend this test if you have symptoms like fatigue, jaundice (yellowing of the skin and eyes), nausea, or dark urine. It’s also commonly prescribed to monitor liver conditions such as hepatitis, fatty liver disease, cirrhosis, or when you’re taking medications that may affect the liver.
Why is the Liver Function Test Important?
The Liver Function Test (LFT) is essential for early detection of liver problems. The liver performs over 500 critical functions in the body from detoxifying chemicals to producing bile that aids in digestion.
If liver damage occurs, it can go unnoticed for a long time because symptoms often appear in the later stages. Regular LFT screening helps detect abnormalities early, allowing for prompt medical management.
Here’s why this test matters:
- Early detection of hepatitis, liver infections, or damage.
- Monitoring liver performance in patients on long-term medications.
- Assessing alcohol-related liver conditions.
- Tracking treatment progress in those with chronic liver disease.
When Should You Get a Liver Function Test?
Doctors may advise a Liver Function Test if you:
- Experience symptoms of liver dysfunction such as fatigue, nausea, abdominal pain, or yellowing of the skin.
- Consume alcohol regularly or have a history of excessive drinking.
- Have a family history of liver disease.
- Take medications that could potentially affect liver function.
- Have viral hepatitis, diabetes, or obesity (risk factors for fatty liver).
- Are undergoing routine health screening or a pre-surgical evaluation.
Even if you feel healthy, getting an annual LFT can be a smart preventive step to ensure your liver is functioning properly.
