The LFT test, also known as the Liver Function Test, is a crucial diagnostic tool. It checks the health of your liver by measuring enzymes, proteins, and bilirubin levels in your blood. This test is widely recommended for individuals showing signs of liver disorders or for routine health checkups.
What is an LFT Test?
The LFT test is a group of blood tests that evaluate how well your liver is functioning. It provides insights into issues like liver inflammation, damage, or infection. The test helps detect conditions such as hepatitis, fatty liver disease, and cirrhosis.
Why is the Liver Important?
The liver is one of the body’s most vital organs. It performs several critical functions, including:
- Detoxification: Removes toxins from the blood.
- Protein Synthesis: Produces essential proteins like albumin.
- Bile Production: Helps digest fats.
- Metabolism: Regulates nutrients and stores energy.
When the liver is damaged, these functions can be disrupted. That’s why an LFT test is essential to monitor liver health.
When Should You Take an LFT Test?
Doctors recommend the LFT test if you experience:
- Yellowing of the skin or eyes (jaundice).
- Fatigue or weakness.
- Unexplained weight loss.
- Nausea or vomiting.
- Swelling in the abdomen or legs.
It is also advised for people with a history of alcohol use, liver disease, or hepatitis.
Components of an LFT Test
The LFT test includes the following key parameters:
- Alanine Aminotransferase (ALT): Indicates liver damage.
- Aspartate Aminotransferase (AST): Measures enzyme levels linked to liver and heart health.
- Alkaline Phosphatase (ALP): Evaluates bile duct issues.
- Bilirubin: Assesses bile production and breakdown.
- Albumin and Total Protein: Checks liver’s protein synthesis ability.
These components provide a comprehensive view of liver function.
How is the LFT Test Done?
The test involves drawing a small sample of blood from your arm. You may need to fast for 8–12 hours before the test. Your doctor will provide specific instructions.
The procedure is quick and typically takes less than five minutes. Results are usually available within 24 hours.
What Do LFT Test Results Mean?
- Normal Results: Indicate that your liver is functioning well.
- Abnormal Results: Suggest liver damage, infection, or other health concerns.
Your doctor will interpret the results and recommend further tests or treatment if needed.
What Causes Abnormal LFT Test Results?
Abnormal levels in an LFT test can result from:
- Alcohol Abuse: Damages liver cells over time.
- Hepatitis: Viral infections that inflame the liver.
- Fatty Liver Disease: Caused by obesity or high cholesterol.
- Liver Cirrhosis: Scar tissue replacing healthy liver tissue.
- Medications: Certain drugs can affect liver function.
Timely diagnosis is crucial to address these issues effectively.
