What is an LFT Test?

by admin in Uncategorized on January 21, 2025

LFT stands for Liver Function Test, a blood test that evaluates the health of your liver by measuring levels of enzymes, proteins, and substances produced or processed by the liver. The test helps detect liver damage, inflammation, or disease.


Key Components of an LFT Test

  1. Alanine Aminotransferase (ALT):
    • An enzyme found in the liver. High levels indicate liver damage.
  2. Aspartate Aminotransferase (AST):
    • Another enzyme linked to liver health, often checked alongside ALT.
  3. Alkaline Phosphatase (ALP):
    • Enzyme linked to bile ducts. Elevated levels may indicate blockage or liver disease.
  4. Bilirubin:
    • A substance produced during the breakdown of red blood cells. High levels cause jaundice and may signal liver or bile duct issues.
  5. Albumin and Total Protein:
    • Proteins produced by the liver. Low levels may indicate liver dysfunction or nutritional deficiencies.
  6. Gamma-Glutamyl Transferase (GGT):
    • Indicates bile duct issues or liver damage, often linked to alcohol use.

Why is an LFT Test Important?

LFTs help diagnose and monitor conditions such as:

  • Hepatitis (viral or autoimmune).
  • Fatty liver disease (alcoholic and non-alcoholic).
  • Cirrhosis or liver fibrosis.
  • Liver cancer or bile duct obstruction.
  • Drug-induced liver injury.

How to Maintain and Improve Liver Health

Your liver plays a crucial role in detoxifying your body, producing bile, and supporting digestion. Here are steps to keep it healthy and, if necessary, help it recover:


1. Adopt a Liver-Friendly Diet

  • Increase Antioxidants: Include fruits like berries, citrus, and vegetables like spinach, broccoli, and carrots.
  • Healthy Fats: Consume avocado, nuts, and olive oil, which are easier on the liver.
  • Limit Processed Foods: Reduce sugar, trans fats, and artificial additives.
  • Hydration: Drink plenty of water to support liver detoxification.

2. Avoid Excess Alcohol

  • Excessive alcohol consumption can lead to fatty liver, cirrhosis, or liver failure. If you drink, stick to moderate levels or abstain entirely.

3. Exercise Regularly

  • Physical activity reduces fat accumulation in the liver and promotes overall health. Aim for at least 30 minutes of moderate exercise most days.

4. Maintain a Healthy Weight

  • Obesity is a major cause of non-alcoholic fatty liver disease (NAFLD). Weight loss through a balanced diet and exercise can reverse early liver damage.

5. Limit Medication and Supplements

  • Overuse of medications like acetaminophen or unregulated supplements can strain the liver. Always consult a doctor before starting new medications.

6. Prevent Infections

  • Protect yourself from hepatitis A, B, and C by:
    • Getting vaccinated (for hepatitis A and B).
    • Practicing safe hygiene and avoiding shared needles.
    • Using safe sexual practices to prevent transmission.

7. Avoid Toxins

  • Minimize exposure to chemicals like pesticides, cleaning agents, and aerosol products. Always use these substances in ventilated areas and wear protective gear.

8. Manage Chronic Conditions

  • Conditions like diabetes or high cholesterol can impact liver health. Proper management of these conditions reduces liver-related complications.
