Understanding Liver Function Tests: What They Reveal About Your Health
The liver plays a vital role in digestion, metabolism, detoxification, and overall health. When it becomes inflamed, damaged, or diseased, symptoms may not always be obvious in the early stages. This is where Liver Function Tests (LFTs) come in. These simple blood tests provide valuable insights into how well your liver is working and can help detect conditions early before they progress.
If you’re experiencing fatigue, jaundice, or digestive problems, or if you’ve been advised to undergo LFTs, this guide will help you understand their purpose, types, and interpretation. For expert evaluation, consulting a liver specialist in Gurgaon like Dr. Mukesh Nandal is essential.
What Are Liver Function Tests?
Liver Function Tests (LFTs) are a group of blood tests that measure different enzymes, proteins, and substances produced by the liver. They help determine whether the liver is functioning normally or if there is damage.
Doctors commonly recommend LFTs for people with:
- Symptoms such as jaundice, dark urine, or abdominal pain
- Risk factors like alcohol use, obesity, or viral hepatitis
- Existing liver conditions such as fatty liver disease or cirrhosis
- Regular monitoring of long-term medications that may affect the liver
Why Are Liver Function Tests Important?
The liver doesn’t always show early warning signs of trouble. LFTs provide crucial information by:
- Detecting liver inflammation or damage
- Monitoring the progression of liver diseases
- Guiding treatment for conditions like fatty liver, hepatitis, or cirrhosis
- Checking how well medications are tolerated
- Helping specialists decide whether advanced care or intervention is needed
For patients with chronic issues, timely testing can make a significant difference in outcomes.
Types of Liver Function Tests
An LFT panel usually includes the following tests:
1. Alanine Transaminase (ALT)
High ALT levels suggest liver cell injury, often due to hepatitis, fatty liver, or alcohol damage.
2. Aspartate Transaminase (AST)
Like ALT, elevated AST indicates liver inflammation but may also reflect muscle damage.
3. Alkaline Phosphatase (ALP)
Raised ALP levels can signal blocked bile ducts, gallstones, or liver disease.
4. Gamma-Glutamyl Transferase (GGT)
GGT is used to detect bile duct problems and alcohol-related liver issues.
5. Bilirubin
Excess bilirubin in the blood causes jaundice and may indicate hepatitis, cirrhosis, or blocked bile ducts.
6. Albumin & Total Protein
Low albumin levels may suggest chronic liver disease or cirrhosis.
7. Prothrombin Time (PT)
Measures blood clotting ability. Prolonged PT may reflect impaired liver function.
Together, these results give doctors a complete picture of how the liver is functioning.
How to Interpret Liver Function Tests?
While results may vary slightly depending on the lab, here’s a general interpretation:
- Mild Elevations (1-2 times normal): Often linked to fatty liver or medication side effects.
- Moderate to Severe Elevations: May suggest hepatitis, cirrhosis, or bile duct obstruction.
- Very High Levels: Can be due to acute viral hepatitis or drug-induced liver injury.
It’s important not to self-diagnose. A liver cirrhosis specialist in Gurgaon can accurately interpret the results in the context of your health history.
What Conditions Can Liver Function Tests Detect?
LFTs are useful in diagnosing and monitoring a range of conditions, such as:
- Fatty Liver Disease: Linked to obesity, diabetes, or alcohol. Early fatty liver treatment in Gurgaon can reverse the condition.
- Viral Hepatitis (A, B, C, E): Causes inflammation and long-term damage if untreated.
- Cirrhosis: Advanced scarring of the liver due to chronic injury. Requires specialist management.
- Liver Cancer: LFTs, combined with imaging, help in diagnosis and monitoring.
- Alcohol-Related Liver Disease: Common in long-term heavy drinkers.
Preparation for a Liver Function Test
Usually, no special preparation is needed. However:
- You may be asked to fast for 8-12 hours before the test.
- Inform your doctor about ongoing medications, as some can affect results.
- Avoid alcohol for 24 hours before testing.
Next Steps After Abnormal Results
If your results are abnormal, your doctor may suggest:
- Additional imaging tests such as ultrasound or CT scan
- FibroScan to measure liver stiffness
- Biopsy in select cases to confirm diagnosis
- Lifestyle modifications including diet, exercise, and limiting alcohol
Consulting a liver specialist in Gurgaon ensures timely evaluation and the right treatment approach.
