About this test
What is a Liver Function Test (LFT)?
A liver function test is a blood panel that checks how well your liver is working. It measures several enzymes, proteins and substances that the liver produces or processes.
Key Parameters
| Test | What it shows |
|---|---|
| ALT (SGPT) | Damage or inflammation of liver cells |
| AST (SGOT) | Liver cell injury and, if high, can also indicate heart or muscle damage |
| ALP | Bone growth, bile duct blockage or liver disease |
| GGT | Bile duct problems, alcohol use or liver disease |
| Bilirubin | Breakdown of red blood cells and liver excretion function |
| Albumin | Liver’s protein‑producing capacity |
| Total Protein | Overall protein status, including liver and kidney function |
| INR (PT) | Blood clotting ability, reflecting liver synthesis of clotting factors |
Why is it done?
- Routine health check‑ups
- Evaluation of symptoms such as jaundice, abdominal pain, fatigue or unexplained weight loss
- Monitoring chronic liver conditions (hepatitis, fatty liver, cirrhosis)
- Screening for drug‑induced liver injury or alcohol‑related damage
Early Detection
LFT can help identify signs of liver disease or bile duct problems, but it does not diagnose on its own. A doctor interprets the results with your symptoms, history and other investigations.
What do abnormal results mean?
- High enzymes (ALT, AST, ALP, GGT) may indicate liver inflammation, hepatitis, fatty liver, bile duct obstruction, or alcohol‑related damage.
- High bilirubin suggests impaired bile excretion or hemolysis.
- Low albumin can point to chronic liver disease, malnutrition or kidney problems.
Many factors—diet, medications, alcohol, recent exercise, hydration—can affect these numbers, so results are considered in context.
Who should get it?
- Adults with risk factors for liver disease (heavy alcohol use, obesity, diabetes, viral hepatitis exposure)
- Patients on hepatotoxic medications
- Individuals with unexplained jaundice, abdominal pain or fatigue
- Routine screening in high‑risk populations
Short summary: A liver function test is a simple blood panel that helps doctors assess liver health and detect potential problems early.
Used for detecting / monitoring
Before your test
Preparation
- Fasting: No fasting required for a standard LFT. If you are also having a fasting glucose or lipid panel, fast for 8–12 hours.
- Medication: Continue your usual medications unless your doctor advises otherwise. Note that some drugs (e.g., statins, anticonvulsants) can affect liver enzymes.
- Hydration: Drink plenty of water the day before; avoid excessive alcohol for 24–48 hours.
- Procedure: A trained phlebotomist will draw 5–10 mL of blood from a vein in your arm. The process takes about 5 minutes and may cause a brief pinch.
- Aftercare: You can resume normal activities immediately. If you feel faint, sit or lie down for a few minutes.
- Confirm with your doctor or lab: Always check specific instructions with your healthcare provider. This information is educational and not a substitute for professional medical advice.
Sample type: Blood
Report parameter guide
ALT
Alanine aminotransferase – enzyme released when liver cells are damaged
Low: may indicate low liver enzyme production or severe liver failure
High: may indicate liver cell injury, hepatitis, fatty liver, or drug toxicity
AST
Aspartate aminotransferase – enzyme found in liver and other tissues
Low: may indicate low enzyme production or severe liver damage
High: may indicate liver injury, hepatitis, heart attack, or muscle damage
ALP
Alkaline phosphatase – enzyme linked to bile ducts and bone
Low: may indicate low bone growth or malnutrition
High: may indicate bile duct obstruction, liver disease, bone disorders, or pregnancy
GGT
Gamma‑glutamyl transferase – enzyme reflecting bile duct function
Low: rarely clinically significant
High: may indicate bile duct blockage, alcohol use, or liver disease
Bilirubin total
Total bilirubin – waste product processed by the liver
Low: may indicate low red blood cell breakdown or liver dysfunction
High: may indicate jaundice, liver disease, bile duct blockage, or hemolysis
Bilirubin direct
Direct (conjugated) bilirubin – processed by the liver
Low: rarely clinically significant
High: may indicate liver cell injury, bile duct obstruction, or hepatitis
Bilirubin indirect
Indirect (unconjugated) bilirubin – before liver processing
Low: rarely clinically significant
High: may indicate increased red blood cell breakdown or early liver dysfunction
Albumin
Albumin – main protein made by the liver
Low: may indicate liver disease, malnutrition, or kidney loss
High: may indicate dehydration or high protein intake
Total protein
Total protein – sum of albumin and globulins
Low: may indicate malnutrition, liver or kidney disease
High: may indicate dehydration, chronic inflammation, or infection
