Your liver is one of the most vital organs in the body, responsible for detoxifying harmful substances, producing essential proteins, and supporting digestion. However, liver diseases often develop silently, showing symptoms only at advanced stages.
A Liver Function Test (LFT) is a simple blood test that helps assess the health of your liver and detect problems early. Whether you’re experiencing symptoms or just want a routine check-up, understanding LFT can help you take control of your health.
What is a Liver Function Test (LFT)?
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 evaluate how well your liver is functioning and identify any damage or inflammation.
Why is a Liver Function Test Important?
LFT is essential for:
- Detecting liver diseases early
- Monitoring conditions like hepatitis or fatty liver
- Evaluating the impact of medications on the liver
- Assessing liver function before surgeries
- Monitoring alcohol-related liver damage
Early diagnosis can prevent serious complications such as liver failure or cirrhosis.
Common Symptoms That Require an LFT
You should consider getting a Liver Function Test if you experience:
- Persistent fatigue
- Yellowing of skin or eyes (jaundice)
- Abdominal pain or swelling
- Dark urine
- Nausea or vomiting
- Unexplained weight loss
Even without symptoms, routine screening is recommended for people with risk factors like obesity, diabetes, or alcohol consumption.
What Does a Liver Function Test Include?
An LFT typically includes the following parameters:
- ALT (Alanine Aminotransferase) – Indicates liver cell damage
- AST (Aspartate Aminotransferase) – Helps detect liver injury
- ALP (Alkaline Phosphatase) – مرتبط with bile ducts
- Bilirubin – Measures liver’s ability to remove waste
- Albumin – Indicates liver’s protein production
- Total Protein – Overall liver function indicator
Liver Function Test Normal Range
Normal values may vary slightly depending on the lab, but generally:
- ALT: 7–56 U/L
- AST: 10–40 U/L
- ALP: 44–147 IU/L
- Bilirubin: 0.1–1.2 mg/dL
- Albumin: 3.5–5.0 g/dL
Abnormal results do not always mean serious disease, but they require further evaluation by a doctor.
Liver Function Test Procedure
The LFT procedure is simple and quick:
- A healthcare professional collects a blood sample from your vein
- The sample is sent to a laboratory for analysis
- Results are usually available within 24 hours
Preparation Tips:
- Fasting for 8–10 hours may be required
- Avoid alcohol before the test
