They help diagnose liver diseases, monitor the progression of liver disease, and assess the effectiveness of treatment.

The Guide to Liver Function Testswill give you a comprehensive outline on everything you need to know about LFTs.


The liver is one of the most crucial organs in the human body, playing a vital role in various processes such as detoxification, metabolism, and digestion.

Unfortunately, the liver is also susceptible to damage and disease, making it important to monitor its health regularly. One of the most common ways to do this is through liver function tests (LFTs).

We will take a look at some of thebest liver function tests, Learn about Liver function Test names and their purposes.

When is a liver Function Test Suggested?

  • From measuring enzyme levels such as Alanine transaminase (ALT) and Aspartate transaminase (AST), to evaluating the presence of yellow pigments like bilirubin and gamma-glutamyl transferase (GGT), LFTs provide a comprehensive overview of the liver’s function.
  • The tests also measure the accurate measurement of total protein and albumin, produced by the liver, and prothrombin time (PT), which estimate and provide accurate information about the liver’s ability to produce factors necessary for blood to clot.

In this section of the mini guide to liver function tests, we will consider the available causes of LFTs and why they are constituted by doctors.

  • Symptoms of liver disease: If a patient is experiencing symptoms such as abdominal pain, jaundice, fatigue, nausea, or loss of appetite, an LFT is generally ordered to determine if liver disease is the underlying cause.
  • Monitoring liver disease progression: A patient has been diagnosed with liver diseases, such as hepatitis or cirrhosis, LFTs are performed regularly by certified doctors to monitor the progression of the disease and assess the effectiveness of treatment.
  • Routine health screenings: They are often part of regular & routine health screenings and performed as part of a comprehensive physical examination or as an extension of a pre-employment or insurance medical exam.
  • Monitoring the effects of medication: Certain medications, such as acetaminophen or prescription drugs, can affect the liver. LFTs are conducted before starting a new medication and periodically during treatment to monitor for information about liver-related side effects.
  • Alcohol abuse: Alcohol abuse has statistically killed more people in India than most of the feared methods to perish and it remains a constant. LFTs are recommended by doctors to individuals who have a history with certain liquid abuse.

A specific LFT measures a completely different but certainly correlated aspect of liver function and health.

A combination of tests and health values must be ascertained effectively to measure specific digitals and to ascertain accurate recommendations

Alanine Transaminase (ALT) Test
ALT is an enzyme primarily found in the liver and is released into the bloodstream when there is liver damage. Elevated levels of ALT can indicate liver disease or injury.

Alkaline Phosphatase Test (ALP)

ALP is an enzyme found in the bile ducts, bone, and liver. Elevated levels of ALP can indicate liver disease or blockage of the bile ducts.

ALBUMIN AND Total Protein Test

  • Albumin is the most abundant protein in the blood and is produced by the liver. Low levels of albumin can indicate liver disease or malnutrition.
  • Total protein measures the amount of protein in the blood, including albumin, which is produced by the liver. Low levels of total protein can indicate liver disease or other health problems.

Aspartate Transaminase (AST) Test

Aspartate transaminase (AST) – AST is an enzyme that is present in many tissues in the body, including the liver. Like ALT, elevated levels of AST can indicate liver damage or disease.

Bilirubin Test

Bilirubin is a yellow pigment formed from the degradation of red blood cells and subsequently processed by the liver before being eliminated in the bile. Elevated levels of bilirubin can indicate liver disease or blockage of the bile ducts.
