An LFT Test (Liver Function Test) is a simple blood test used to check if your liver is working the way it should. It helps doctors see if your liver is working properly or if there could be a problem.
The test looks at specific proteins and enzymes in your blood that give clues about your liver’s health. Some show how well your liver is doing its job, like making important proteins and removing waste. Some results can show if your liver is irritated or has been hurt.
If the results are unusual, it doesn’t always mean there’s a major problem. Your doctor will explain what the results mean and guide you on the next steps.
Types of Liver Tests
- ALT (Alanine Aminotransferase):
Enzymes are mostly in the liver. High levels may mean liver damage.
- AST (Aspartate Aminotransferase):
Found in liver, heart, and muscles. High levels could suggest problems with your liver or muscles. Usually checked with ALT.
- GGT (Gamma Glutamyl Transpeptidase):
Mainly in the liver. High GGT may mean liver or bile duct issues.
- Bilirubin (Total & Direct):
Waste from breaking down red blood cells. High levels can cause jaundice.
● Total: Overall level
● Direct: Processed by the liver
- ALP (Alkaline Phosphatase):
Found in the liver and bones. High levels may mean liver inflammation or blocked bile ducts.
- Albumin:
Main liver-made protein. Low levels could indicate that the liver isn’t functioning properly.
- Total Protein:
Measures all blood proteins. Helps check liver, kidney, or nutrition problems.
- Ammonia Test:
Checks for high ammonia in blood, which can happen if the liver isn’t working right.
- Ceruloplasmin Test:
Checks copper-carrying protein. Helps diagnose Wilson disease (a rare liver condition).
- Bile Acids, Total:
High levels might suggest liver conditions like hepatitis or cirrhosis.
- NAFLD Fibrosis Score:
Estimates liver scarring in fatty liver disease using other liver test results.
When to Get Tested
● Check for liver infections like hepatitis
● Keep an eye on liver diseases, like fatty liver or alcohol-related liver problems
● See how well treatment is working
● Look for signs of serious damage, like cirrhosis (liver scarring)
● Watch for side effects from certain medicines
If your test results are too high or too low, it might mean there’s a liver problem. The results, along with your symptoms, help doctors find the cause.
Preparing for Liver Test
Some foods and medicines can change your liver function test results. Your doctor may tell you to stop eating or skip some medicines before your blood test.
What Happens During the Test
● A nurse or technician will collect a small sample of your blood.
● They’ll use a thin needle and put it into a vein in your arm, usually near your elbow.
● The blood goes into a small tube.
● You may feel a small prick when the needle is inserted.
● Your arm may feel sore for a short time after.
That’s it! The whole process is quick and simple.
