The liver performs many important functions in the body, including processing nutrients, helping remove waste products and producing essential proteins. A Liver Function Test, commonly known as an LFT, is a group of blood tests that helps assess different parameters related to liver health.
Liver health may be monitored as part of a routine health checkup or when a doctor recommends testing based on symptoms, medical history or existing health conditions. Understanding the purpose of an LFT can help you know when this blood test may be useful.
What Is a Liver Function Test (LFT)?
A Liver Function Test is a blood test panel that measures different enzymes, proteins and substances associated with the liver.
Depending on the laboratory and test package, an LFT may include:
SGPT (ALT)
SGOT (AST)
Alkaline Phosphatase (ALP)
Total Bilirubin
Direct Bilirubin
Indirect Bilirubin
Total Protein
Albumin
Globulin
A/G Ratio
The exact parameters included can vary depending on the selected test or health checkup package.
Why Is a Liver Function Test Recommended?
A doctor may recommend an LFT for routine health monitoring, to investigate certain symptoms or to monitor an existing medical condition.
Liver function testing may be considered for people experiencing symptoms such as persistent tiredness, loss of appetite, nausea, abdominal discomfort, dark-coloured urine or yellowing of the eyes or skin.
Testing may also be recommended for people with certain health conditions, individuals taking long-term medications or those undergoing regular preventive health checkups.
What Do Common LFT Parameters Check?
SGPT (ALT)
SGPT, also called ALT, is an enzyme found mainly in liver cells. Changes in ALT levels may provide useful information when assessing liver-related health.
SGOT (AST)
SGOT, also known as AST, is an enzyme found in the liver and other tissues. Doctors usually interpret AST results together with other test parameters.
Bilirubin
Bilirubin is produced during the normal breakdown of red blood cells. The liver helps process bilirubin. LFT reports may include total, direct and indirect bilirubin measurements.
Alkaline Phosphatase (ALP)
ALP is an enzyme associated with different tissues, including the liver and bones. Its interpretation depends on other laboratory findings and the person's overall health condition.
Albumin and Total Protein
Albumin and other proteins perform important functions in the body. These values may also be included when assessing different aspects of liver-related health.
Does a Liver Function Test Require Fasting?
Fasting requirements depend on the tests being performed.
An LFT alone may not always require fasting. However, if the test is booked together with a lipid profile, fasting blood sugar or a complete health checkup package, fasting may be required.
It is always best to confirm the preparation instructions before giving your blood sample.
How Is an LFT Performed?
A Liver Function Test is performed using a blood sample.
The usual process includes:
Booking the required test
Confirming any fasting or preparation instructions
Blood sample collection by a trained professional
Laboratory testing
Receiving the diagnostic report
For people who cannot easily visit a diagnostic centre, home sample collection can provide a convenient alternative.
