LFT (Liver Function Tests)

Overview:
Liver Function Tests (LFTs) are a group of blood tests that assess the health and function of the liver. The liver plays a vital role in digestion, detoxification, metabolism, and the production of proteins that help with blood clotting. These tests measure various enzymes, proteins, and substances in the blood to evaluate liver function and detect liver damage or disease.

What it detects:
LFTs measure several key markers, including:

Alanine Aminotransferase (ALT): An enzyme that helps break down proteins; high levels can indicate liver damage.

Aspartate Aminotransferase (AST): An enzyme found in the liver, heart, and muscles; elevated levels may indicate liver damage or muscle injury.

Alkaline Phosphatase (ALP): An enzyme related to bile ducts; elevated levels can indicate liver or bone disorders.

Bilirubin: A substance produced by the breakdown of red blood cells; high levels can indicate liver disease or bile duct obstruction.

Albumin: A protein made by the liver; low levels can indicate liver dysfunction or malnutrition.

Total Protein: Measures the total amount of proteins in the blood, including albumin; abnormal levels may suggest liver or kidney disease.

These tests are commonly used to monitor liver health, diagnose liver diseases (e.g., hepatitis, cirrhosis, fatty liver disease), and assess liver function in people with known liver conditions.

Who should get it:
Individuals with symptoms of liver disease, such as jaundice (yellowing of the skin or eyes), abdominal pain, nausea, or fatigue, should consider this test. It is also recommended for individuals with a history of alcohol consumption, viral infections (e.g., hepatitis), obesity, or those taking medications that can affect the liver.

Sample required:
A blood sample is required for this test.

Fasting requirements:
Fasting is not usually required, but it may be recommended in some cases to ensure accurate results.

Processing time:
Results available on Same Day.
