Hello welcome to our Biology Ranker website. In today’s article (Liver Function Test), we are going to provide you with a detailed analysis of liver function tests and what is the benefit of these tests,s and how they are important for you. We request you that please read the article from the start point to the end point so that everything is clear in your understanding.
Some important types of question people generally asked such, What Is Lft, Normal Liver Function Tests Values, Liver Function Tests Normal Values, Liver Function Tests Normal Ranges, Liver Function Tests Cost, Liver Function Tests Results Explained, Liver Blood Test Name, How Can I Check My Liver Health at Home, What Is Liver Function Tests, Liver Function Tests, What Is Lft Test, Liver Blood Test, Liver Enzymes, Liver Function Tests Name, etc.
What are the Liver function tests?
The liver of any human body is the vital organ of the body. And we need a good liver to survive a healthy life. But if our liver does not function correctly it is called abnormal liver. And that’s why we need liver function tests. Liver function test at a trial of the blood that tells about the enzymes, hormones, and other essential proteins that are secreted by the liver.
A liver function test analyzes any abnormality happening in the liver by the blood sample. There are many important so much important substances like proteins as well as enzymes that are needed to work for a liver in a good way.
Important Substances Diagnosed in LTFs
We are giving you the list below of some important proteins and enzymes and others that are diagnosed in the liver function test:
- The very first is Albumin protein, this Albumin protein is made as well as secreted by the liver. This is a very much essential and vital protein for life.
- On the second number, we made a diagnosis of the total proteins available in the blood as well as the critical amount present in the blood.
- ALP (alkaline phosphatase), ALT (alanine transaminase), AST (aspartate aminotransferase), and GGT (gamma-glutamyl transferase) are enzymes produced by the liver. These enzymes play important roles in various liver functions and are commonly used as indicators or markers of liver health and function in medical tests.
- There is also a waste product produced by the liver that is called bilirubin. This belief is stored in the gallbladder.
- Lactate dehydrogenase (LD) is a very important enzyme that is present in almost all cells of the human body. The primary role is to make the conversion of lactate into pyruvate, which is used in cellular metabolism. However, when cells are damaged or injured due to various diseases or injuries, LD is released into the bloodstream.
- Another important protein is used to plot the blood on the injury. This protein is called Prothrombin time.
How to know that the liver is not functioning well?
After doing the liver function test if one or more of these substances showing the out range parameter from the normal range it can be a sign of liver malfunctioning.

Uses of Liver Function Test?
Liver function tests (LFTs) are a collection of blood tests that provide important information about the liver’s health and function. These tests aid healthcare practitioners in evaluating liver function, diagnosing liver illnesses, monitoring ongoing liver problems, and determining therapy efficacy. Here are some common uses for liver function tests:
Screening and general assessment: LFTs are frequently performed as part of routine health check-ups to monitor overall liver function, particularly in persons who may be at increased risk for liver illnesses, such as those with a history of alcohol misuse, hepatitis infection, or certain drugs.
Diagnosis of liver disease: Abnormal LFT values are indicative of the existence of liver disease. Higher levels of liver enzymes such as ALT, AST, and ALP may indicate liver injury or inflammation, whereas deviations in bilirubin levels may indicate bile production. LFTs help in the diagnosis of disorders such as hepatitis, liver cirrhosis, non-alcoholic fatty liver disease (NAFLD), autoimmune liver diseases, and others.
Monitoring liver diseases: LFTs can be used to track the progress of liver illnesses, estimate the severity of liver damage, and measure the efficiency of therapy strategies. Serial LFTs may help in the monitoring of disease progression or response to medications by tracking changes in liver enzyme levels over time.
Disease diagnosed by Liver function test
Now we are going to provide you the list of diseases diagnosed by the liver function test. Liver function tests (LFTs) may help in the detection and assessment of a variety of liver diseases. The following are some of the most common liver conditions that can be detected by LFTs:
Hepatitis: Liver function tests (LFTs) are commonly utilized to diagnose several kinds of hepatitis, including viral hepatitis (such as hepatitis A, B, or C), autoimmune hepatitis, and drug-induced hepatitis. LFTs can detect the presence and progression of liver cirrhosis, late-stage damage of the liver caused by chronic liver disorders such as hepatitis or alcohol consumption.
Non-alcoholic Fatty Liver Disease (NAFLD): LFTs can be used for the diagnosis of NAFLD, which is marked by fat accumulation in the liver that isn’t caused by alcohol usage.
Alcoholic Liver Disease: LFTs can help in the diagnosis and monitoring of liver damage induced by excessive alcohol consumption, such as alcoholic fatty liver disease, alcoholic hepatitis, and alcoholic cirrhosis.
Drug-Induced Liver Injury: LFTs can detect liver damage caused by particular medications, herbal supplements, or toxins, resulting in determining the cause of drug-induced liver problems.
Biliary Diseases: LFTs can help in the identification of bile ducts or gallbladder diseases such as bile duct obstruction, gallstones, or primary biliary cholangitis.
Frequently Asked Questions about Liver Function Test:
1. What is a liver function test?
A liver function test is a blood test that analyzes the levels of enzymes, hormones, and proteins secreted by the liver to assess its overall health and functioning.
2. Why is a liver function test performed?
A liver function test is performed to detect and diagnose any abnormalities or diseases affecting the liver, such as liver damage, liver inflammation, liver infections, and liver diseases like hepatitis.
3. What are the important substances analyzed in liver function tests?
A liver function test analyzes important substances such as albumin protein, total protein levels, enzymes like alanine aminotransferase (ALT) and aspartate aminotransferase (AST), bilirubin, alkaline phosphatase, and gamma-glutamyl transferase (GGT).
4. What does albumin protein signify in liver function tests?
Albumin protein is produced and secreted by the liver. A decrease in albumin levels may indicate liver dysfunction or disease, as this protein plays a vital role in maintaining fluid balance and transporting hormones and other substances in the body.
5. How is a liver function tests performed?
A liver function test is performed by taking a blood sample from a vein in your arm. These samples after collection sent to a laboratory for detailed analysis.
5. Is any preparation needed before a liver function test?
Preparation instructions may vary depending on the healthcare provider. However, fasting for a certain period of time (usually 8-12 hours) may be required before the test to obtain accurate results.
6. Are there any risks associated with a liver function test?
A liver function test is a simple
