What Is Liver Test ?
A Liver Test , also called a liver function test (LFT), is a blood test that measures different enzymes, proteins, and substances in the liver to assess its health and function.
Doctors order liver tests to:
Check for liver diseases (e.g., hepatitis, fatty liver, cirrhosis).
Monitor liver damage from alcohol, infections, or medications.
Diagnose jaundice (yellowing of the skin/eyes).
Track liver function in people with existing liver conditions.
ALT (Alanine Aminotransferase): Detects liver damage.
AST (Aspartate Aminotransferase): Assesses liver and heart function.
ALP (Alkaline Phosphatase): Evaluates bile duct issues.
Bilirubin: High levels indicate liver disease or bile duct problems.
Albumin & Total Protein: Measures liver’s ability to make proteins.
A blood sample is drawn from a vein.
Some tests may require fasting (avoiding food for a few hours before).
Importance Of Liver Test
A Liver Test (Liver Function Test - LFT) is crucial for assessing liver health and detecting potential issues early. Here’s why this test is important:
Helps diagnose hepatitis, fatty liver disease, cirrhosis, and liver infections before symptoms appear.
Early detection allows for timely treatment and better outcomes.
Identifies damage caused by alcohol, medications, toxins, or infections.
Helps prevent further liver deterioration and complications.
High bilirubin levels can indicate jaundice, gallbladder issues, or bile duct blockages.
Assists in diagnosing digestive disorders linked to liver function.
Essential for people with chronic liver disease, hepatitis, or cirrhosis.
Monitors disease progression and treatment effectiveness.
Some medications (e.g., painkillers, cholesterol drugs, antibiotics) can affect the liver.
Regular tests ensure safe medication use without liver damage.
Benefits Of Liver Test
The liver plays a major role in detoxifying the body, digestion, and metabolism.
A liver test ensures it is functioning properly to keep the body healthy.
High bilirubin levels can indicate jaundice, gallbladder problems, or bile duct blockages.
Helps in diagnosing conditions that affect digestion and liver function.
Essential for people with chronic liver disease, hepatitis, or cirrhosis.
Helps monitor disease progression and evaluate treatment effectiveness.
Some medications (e.g., painkillers, antibiotics, cholesterol drugs) can stress the liver.
Regular tests ensure the liver is processing medications properly and safely.
