Liver Function Test (LFT): Why It’s Important & What Results Mean
Introduction
Your liver is one of the most vital organs in your body, responsible for digestion, metabolism, detoxification, and more. When the liver is not working properly, it can lead to serious health issues that may go unnoticed in the early stages. That’s where the Liver Function Test (LFT) comes in. This simple blood test gives doctors important insights into your liver’s health. At clinics like Gastro Liver Care Pune, LFTs are a routine but essential diagnostic tool to ensure your liver is functioning well.
What Is a Liver Function Test (LFT)?
A Liver Function Test is a set of blood tests that measure specific enzymes, proteins, and substances produced by the liver. These markers help evaluate liver function and detect any damage, infection, or disease.
Key Components of LFT
- Alanine Aminotransferase (ALT): High levels suggest liver injury or hepatitis.
- Aspartate Aminotransferase (AST): Elevated in liver or muscle damage.
- Alkaline Phosphatase (ALP): Increased levels may point to bile duct issues or liver disease.
- Bilirubin: High bilirubin causes jaundice and indicates liver or bile duct problems.
- Albumin and Total Protein: Low levels suggest reduced liver function.
- Gamma-Glutamyl Transferase (GGT): Often elevated in alcohol-related liver damage.
Why Is LFT Important?
- Early Detection of Liver Diseases: Conditions like hepatitis, cirrhosis, and fatty liver can be caught early.
- Monitoring Existing Conditions: Patients with chronic liver disease need regular monitoring.
- Checking Medication Effects: Certain medicines can harm the liver; LFTs help track this.
- Evaluating Overall Health: A healthy liver means better digestion, energy, and immunity.
Symptoms That May Require an LFT
You should consult a gastroenterologist if you notice:
- Yellowing of skin and eyes (jaundice)
- Persistent fatigue or weakness
- Abdominal pain or swelling
- Dark urine or pale stools
- Nausea, vomiting, or loss of appetite
At Gastro Liver Care Pune, doctors recommend LFTs for anyone experiencing these symptoms to ensure timely diagnosis.
What Do the Results Mean?
- Mildly Elevated Levels: Could be due to medications or temporary infection.
- Significantly Elevated Levels: Suggests hepatitis, liver inflammation, or bile duct blockage.
- Low Protein or Albumin Levels: May indicate chronic liver disease or nutritional deficiency.
Interpretation should always be done by a qualified gastroenterologist.
How to Prepare for an LFT
- Fast for 8–12 hours if instructed.
- Avoid alcohol before the test.
- Inform your doctor about current medications.
