Liver Function Test (LFT)
What is an LFT test?
Why is the LFT test done?
- Detect liver infections like hepatitis
- Check for fatty liver or alcohol-related liver damage
- Monitor side effects of medicines
- Evaluate jaundice or abnormal bilirubin levels
- Assess overall liver health during routine check-ups
What does the LFT test measure?
- Bilirubin (Total, Direct, Indirect) – Indicates liver’s ability to process waste
- SGOT / AST (Aspartate Transaminase) – Enzyme released when liver is damaged
- SGPT / ALT (Alanine Transaminase) – Enzyme that increases in liver injury
- Alkaline Phosphatase (ALP) – Linked to bile duct or bone disorders
- Total Protein & Albumin – Reflect liver’s protein-synthesizing function
- Globulin & A/G Ratio – Help assess immune and liver balance

More Frequently Asked Questions
Do I need to fast before the LFT test?
Yes, fasting for 8–10 hours is recommended for accurate results, especially if other tests like lipid profile are being done along with LFT.
What are the normal ranges in LFT?
Typical reference values (may vary slightly by lab):
- – Bilirubin (Total): 0.2 – 1.2 mg/dL
- – SGOT (AST): up to 40 U/L
- – SGPT (ALT): up to 40 U/L
- – ALP: 44 – 147 U/L
- – Albumin: 3.5 – 5.5 g/dL
What does a high SGPT or SGOT mean?
- – Elevated SGPT/SGOT levels may indicate liver inflammation, fatty liver, viral hepatitis, alcoholic liver disease, or drug-induced liver injury.
- – Further evaluation may be needed depending on the cause.
Can LFT detect fatty liver?
Yes, high ALT (SGPT) or AST (SGOT) levels can suggest fatty liver, though ultrasound or FibroScan may be advised for confirmation.
What causes high bilirubin?
High bilirubin levels cause jaundice (yellowing of skin/eyes). It may be due to hepatitis, bile duct blockage, hemolysis, or liver dysfunction.
Is the LFT test safe and simple?
Yes. It only requires a small blood sample collected by trained phlebotomists. The procedure is safe and takes just a few minutes.
How long will it take to get the results?
At Mitra Diagnostics, LFT results are typically ready within a few hours. Reports are available both online and via WhatsApp.
Can I get the LFT test done at home?
Yes! Mitra Diagnostics offers home sample collection for your convenience. Our team visits your home and delivers reports digitally.
What are the symptoms that may require an LFT test?
You should consider getting an LFT done if you experience:
- – Yellowing of eyes or skin
- – Fatigue or weakness
- – Loss of appetite
- – Nausea or vomiting
- – Abdominal pain or swelling
- – Dark urine or pale stool
How often should I get an LFT done?
- – Once a year during routine health check-up
- – If you are on long-term medication (especially for diabetes, cholesterol, or TB)
- – If you consume alcohol regularly or have a history of liver disease
Can medications affect LFT results?
- Yes. Some painkillers, antibiotics, and cholesterol medicines can temporarily raise liver enzymes. Always inform your doctor about your current medications.
What should I do if my LFT results are abnormal?
Do not panic — mild variations can occur. Consult your doctor for interpretation. They may suggest lifestyle changes, repeat testing, or further imaging if needed.
Can LFT detect liver cancer?
LFT can indicate liver dysfunction, but it cannot diagnose cancer directly. If results are abnormal, your doctor may recommend ultrasound, CT, or specific tumor marker tests.
