Understanding the Liver and Its Functions
The liver is a vital organ responsible for over 500 functions, including detoxification, protein synthesis, bile production, and metabolism of nutrients and medications. Regular monitoring helps identify problems before they become severe.
Common Liver Conditions: Fatty liver disease, hepatitis (viral or alcoholic), cirrhosis, liver infections, and medication-induced damage.
Risk Factors: Excessive alcohol consumption, obesity, viral infections such as hepatitis B, found with an HBsAg test, or hepatitis C, diabetes, certain medications, and family history.
Lifestyle Tips for Liver Health: Maintain a balanced diet rich in fruits and vegetables, limit alcohol, exercise regularly, avoid unnecessary medications, and stay vaccinated against hepatitis.
What is a Liver Function Test?
A liver function test (LFT) is a group of blood tests that measure various enzymes, proteins, and substances produced or processed by the liver. These tests assess liver damage, inflammation, or impaired function.
- Common parameters include:
- Alanine aminotransferase (ALT)
- Aspartate aminotransferase (AST)
- Alkaline phosphatase (ALP)
- Gamma-glutamyl transferase (GGT)
- Total bilirubin
- Direct bilirubin
- Albumin
- Total protein
- These help distinguish between different types of liver issues, such as hepatocellular damage or cholestasis (bile flow obstruction).
When Should You Get a Liver Function Test?
Consider an LFT if you experience persistent symptoms or have risk factors. Common indicators include unexplained fatigue, loss of appetite, dark urine, pale stools, or swelling in the abdomen/legs.
- Routine screening for those with chronic conditions like diabetes or obesity.
- Monitoring during long-term medication use (e.g., statins, painkillers).
- Follow-up after viral hepatitis exposure or alcohol overuse.
Procedure for the Liver Function Test
The test is simple and safe:
A small blood sample is taken from a vein in your arm.
No special preparation is usually needed, though fasting for 8-12 hours may be advised for accurate bilirubin results.
The sample is analysed in the laboratory, with results typically available within a few hours to 1-2 days.
Minimal discomfort occurs, similar to a routine blood draw.
Interpreting Liver Function Test Results
- Results are compared to reference ranges, which may vary slightly by laboratory, age, and gender. Abnormal values require clinical correlation.
- Liver function test normal range (approximate values; always refer to your lab report):
- ALT: 7 to 55 U/L
- AST: 8 to 48 U/L
- ALP: 40 to 129 U/L
- GGT: 8 to 61 U/L
- Total Bilirubin: 0.1 to 1.2 mg/dL
- Albumin: 3.5 to 5.0 g/dL
- Total Protein: 6.3 to 7.9 g/dL
- Elevated enzymes often indicate damage, while low albumin suggests chronic issues. Your doctor will explain patterns (e.g., ALT/AST ratio) for accurate diagnosis.
