LFT Meaning: Understanding Liver Function Test Results
🩺 Understanding Liver Function Tests (LFT): What Your Results Mean
LFT meaning is one of the most searched topics when people receive abnormal liver test reports. Liver Function Tests (LFT) are essential blood tests that help evaluate how well your liver is working. Understanding LFT meaning can help you detect early liver problems and take timely action.
One of the most common diagnostic tools used to evaluate liver health is the Liver Function Test (LFT). If you’ve recently undergone this test and received a report filled with unfamiliar medical terms, you’re not alone.
In this comprehensive guide, Dr. Akanand Singh, a leading liver transplant surgeon and hepatobiliary specialist, explains what LFT is, what each parameter means, and when you should be concerned.
🧪 LFT Meaning: What is a Liver Function Test?
A Liver Function Test (LFT) is a group of blood tests that measure different enzymes, proteins, and substances produced by the liver. These tests help doctors assess how well your liver is functioning and detect any damage or disease.
LFT is commonly recommended for:
- Routine health checkups
- Monitoring liver diseases
- Evaluating symptoms like jaundice, fatigue, or abdominal pain
- Checking effects of medications on the liver

🔬 LFT Meaning Explained: Key Components of the Test
Understanding each component of LFT is crucial to interpreting your results correctly.
1. ALT (Alanine Aminotransferase)
ALT is an enzyme found primarily in the liver. When liver cells are damaged, ALT leaks into the bloodstream.
Normal Range: 7–56 U/L
High ALT may indicate:
- Fatty liver disease
- Hepatitis
- Liver injury
- Alcohol-related liver damage
🩺 According to Dr. Akanand Singh, elevated ALT is often the earliest sign of liver stress.
2. AST (Aspartate Aminotransferase)
AST is another enzyme found in the liver, heart, and muscles.
Normal Range: 10–40 U/L
High AST may indicate:
- Liver damage
- Muscle injury
- Alcoholic liver disease
3. ALP (Alkaline Phosphatase)
ALP is an enzyme related to bile ducts.
Normal Range: 44–147 IU/L
High ALP may indicate:
- Bile duct obstruction
- Gallstones
- Liver disease
4. Bilirubin
Bilirubin is a yellow pigment formed from the breakdown of red blood cells.
Normal Range: 0.1–1.2 mg/dL
High bilirubin leads to:
- Jaundice (yellowing of skin and eyes)
- Liver disease
- Bile duct blockage
🩺 Dr. Akanand Singh emphasizes that persistent high bilirubin should never be ignored.
5. Albumin
Albumin is a protein made by the liver that helps maintain fluid balance.
Normal Range: 3.5–5.0 g/dL
6. Total Protein
Measures total protein in blood.
7. GGT (Gamma-Glutamyl Transferase)
Helps detect bile duct and alcohol-related liver issues.
📊 LFT Meaning in Reports: Normal vs Abnormal Results
It’s important to understand that slightly abnormal results do not always mean serious disease.
✅ Mild Elevation
- Fatty liver or temporary causes
⚠️ Moderate Elevation
- Hepatitis or inflammation
🚨 Severe Elevation
- Serious liver damage
⚠️ Common Causes of Abnormal LFT
Dr. Akanand Singh highlights:
🍔 Fatty Liver Disease
Most common cause due to poor lifestyle
🍺 Alcohol Use
Damages liver cells over time
🦠 Hepatitis
Viral infection
💊 Medications
Certain drugs affect liver
🧠 Symptoms You Should Not Ignore
- Yellow eyes (jaundice)
