What Does a Liver Function Test Show? Understand Your Report Clearly
You’ve done a Liver Function Test (LFT)…

SGPT
SGOT
Bilirubin
Confusing?
Don’t worry — this guide will help you understand what your liver test actually shows in simple language.
What is a Liver Function Test (LFT)?
A Liver Function Test (LFT) is a group of blood tests that check how well your liver is working.
It helps detect:
- Liver damage
- Infections
- Fatty liver
- Inflammation
What Does an LFT Measure?
Let’s break down the main components
1. SGPT (ALT)
Think of it as a liver damage marker
- High SGPT = Liver stress or damage
- Common in fatty liver, alcohol damage
Higher levels = concern
2. SGOT (AST)
Another enzyme linked to liver and muscle health
- Elevated levels may indicate:
- Liver injury
- Muscle issues
3. Bilirubin
This measures how your liver processes waste.
- High bilirubin can cause:
- Yellowing of skin (jaundice)
- Dark urine
Indicates liver dysfunction
4. Alkaline Phosphatase (ALP)
Linked to bile flow and liver function
- High levels may indicate:
- Blockage in bile ducts
- Liver disease
5. Total Protein & Albumin
These show how well your liver produces proteins.
- Low levels may indicate:
- Liver damage
- Nutritional issues
What a Liver Test Actually Tells You
A Liver Function Test helps identify:
- Liver inflammation
- Fatty liver disease
- Liver infection (hepatitis)
- Alcohol-related damage
- Blockages in bile flow
It gives a complete picture of liver health
Important Point Most People Miss
A single value is not enough.
Doctors look at:
- Combination of values
- Trends over time
That’s how accurate diagnosis is made
Symptoms That May Need an LFT
You should consider testing if you have:
- Fatigue or weakness
- Loss of appetite
- Abdominal pain
- Yellowing of eyes/skin
- Unexplained weight loss
These may indicate liver problems

Show no symptoms in early stages
By the time symptoms appear, damage may already be advanced
That’s why regular testing is important
Who Should Get LFT Done?
You should test if you:
- Consume alcohol regularly
- Have obesity or belly fat
- Have diabetes or high cholesterol
- Take long-term medications
These increase risk of fatty liver and liver damage
Can Liver Health Be Improved?
