The Liver Function Test (LFT) is an essential diagnostic tool used to evaluate how well your liver is working. The liver plays a major role in metabolism, detoxification, and nutrient storage, making it one of the body’s most vital organs. If your doctor suspects liver disease, or you’re experiencing symptoms like fatigue, nausea, or jaundice, you may be advised to undergo an LFT to assess your liver’s health.
At Khan Lab and Diagnostic Centre, a trusted name in Pakistan’s healthcare sector, the Liver Function Test is conducted using modern, fully automated biochemical analyzers. The lab ensures precision, reliability, and timely results giving patients complete confidence in their health reports.
Whether you’re screening for hepatitis, fatty liver, or monitoring treatment progress, the Khan Lab LFT provides comprehensive insights into your liver’s functioning.
What is the Liver Function Test (LFT)?
The Liver Function Test, commonly abbreviated as LFT, measures the levels of various liver enzymes, proteins, and substances in your blood. These values help determine how well your liver is performing its many roles from filtering toxins to producing bile and essential proteins.
The test usually includes the following parameters:
- Alanine Aminotransferase (ALT)
- Aspartate Aminotransferase (AST)
- Alkaline Phosphatase (ALP)
- Total and Direct Bilirubin
- Albumin (ALB)
- Total Protein (TP)
- Gamma-Glutamyl Transferase (GGT)
- A/G Ratio (Albumin/Globulin Ratio)
Doctors recommend an LFT if you have symptoms of liver disorders, consume alcohol frequently, take long-term medications, or have a history of viral hepatitis.
Why is the Liver Function Test Important?
The LFT provides critical information about your liver’s ability to process nutrients and eliminate toxins. Detecting liver dysfunction early allows for timely treatment and prevents progression to severe conditions like cirrhosis or liver cancer.
This test helps in:
- Detecting hepatitis, fatty liver disease, or cirrhosis
- Monitoring side effects of medications that may affect the liver
- Evaluating alcohol-related liver damage
- Assessing overall metabolic health
- Monitoring progress during liver treatment
In short, the Liver Function Test is an essential part of preventive healthcare for adults, especially those at risk of liver problems.
When Should You Get a Liver Function Test (LFT)?
You should consider an LFT if you experience:
- Persistent fatigue or weakness
- Yellowish skin or eyes (jaundice)
- Abdominal swelling or pain
- Dark urine or pale stool
- Loss of appetite or nausea
- History of hepatitis, alcohol use, or obesity
Additionally, doctors recommend regular LFTs for patients taking cholesterol-lowering drugs, painkillers, or anti-tuberculosis medicines.
How to Prepare for the Liver Function Test (LFT)?
To ensure accurate results, follow these simple preparation tips:
- Fasting: Avoid eating or drinking (except water) for 8-12 hours before the test.
- Avoid Alcohol: Refrain from drinking alcohol for at least 24 hours before testing.
- Medication: Inform your doctor about all medications and supplements you take.
- Diet: Avoid high-fat or oily meals the day before.
- Stay Hydrated: Drink plenty of water to make blood collection easier.
Following these steps helps ensure the Khan Lab LFT results accurately reflect your liver’s true condition.

Liver Function Test (LFT) Report & Normal Values
| Parameter | Normal Range |
| ALT (Alanine Aminotransferase) | 7 – 56 U/L |
| AST (Aspartate Aminotransferase) | 10 – 40 U/L |
| ALP (Alkaline Phosphatase) | 44 – 147 U/L |
| Total Bilirubin | 0.1 – 1.2 mg/dL |
| Direct Bilirubin | 0.0 – 0.3 mg/dL |
| Albumin | 3.5 – 5.0 g/dL |
| Total Protein | 6.0 – 8.3 g/dL |
| GGT | 9 – 48 U/L |
| A/G Ratio | 1.0 – 2.5 |
Your doctor interprets these values to detect possible liver dysfunctions. Deviations may indicate conditions like hepatitis, liver inflammation, or bile duct obstruction.
Understanding Abnormal Results
Abnormal LFT values can signal several medical conditions:
- High ALT/AST: May indicate liver inflammation or viral hepatitis.
- Increased ALP: Could point to bile duct blockage or bone disorders.
- High Bilirubin: Suggests jaundice or impaired bile flow.
- Low Albumin: May indicate poor liver function or malnutrition.
Your physician may recommend further imaging or blood tests to identify the root cause. Avoid self-interpretation, always discuss your report with a qualified doctor.
