What Blood Test Is For Liver Function – Liver function tests (also called a liver panel) are blood tests that measure various enzymes, proteins, and other substances made by the liver. These tests check the overall health of your liver. Different substances are often tested in a blood sample at the same time, and may include:

If the level of one or more of these substances is outside the normal range, it may be a sign of liver disease.

You may also need these tests if you have certain risk factors. You may be at higher risk for liver disease if you:

A healthcare professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected in a test tube or glass. You may feel a small sting when the needle goes in or out. This usually takes less than five minutes.

There is very little risk to having a blood test. You may have slight pain or bruising where the needle was inserted, but most symptoms go away quickly.

If your liver function test results are abnormal, it may mean that your liver is damaged or not working properly. Liver damage can be caused by a number of different conditions, including:

If your liver function tests are not normal, your provider may need other tests to confirm or rule out a specific diagnosis. These tests may include other blood tests and/or a liver biopsy. A biopsy is a procedure that removes a small sample of tissue for testing.

The liver is involved in many metabolic, digestive, filtration and hormonal functions. It is also the largest organ in our body and weighs more than one kilogram.

In addition to producing cholesterol to strengthen our cell structure, the liver also maintains the chemical balance in our blood, secretes bile that helps filter metabolic waste, aids in the digestion of fat, and converts glucose into glucose. Stores The liver can also be considered a gland because of the secretion of bile juice and its hormonal functions, especially in the chemical transformation of thyroid hormones.

Many enzymes and proteins are synthesized in the liver. In addition to its role in secreting albumin, it is another protein that regulates blood volume.

Proteins produced in the liver are involved in cellular functions including digestion and the transport of cholesterol in the blood throughout the body.

Liver Function Tests: Indication And Interpretation

The liver also produces enzymes that speed up chemical and molecular functions in our body including amino acid (protein) metabolism. The main enzymes made in the liver cells and bile ducts are alkaline phosphatase (ALP), alanine transaminase (ALT), aspartate transaminase (AST) and gamma-glutamyltransferase (GGT). However, these enzymes should not be found in the blood if the liver is healthy. They only enter the bloodstream if there is a major liver infection or inflammation.

“Liver function tests are a group of blood tests that help diagnose and monitor liver disease or damage. These tests measure the levels of certain enzymes and proteins in the blood,” says Dr. Ravindra Nidhoni, Consultant, Liver Transplant Surgery, Fortis Hospital, Bannerghatta Road, Bangalore explains. Elevated enzyme levels detected indicate hepatocyte (liver cell) damage.

According to Dr. Prasanna Bhatt KS, Consultant, Hepatology and Transplant Physician, Manipal Hospitals, Bangalore, the liver function test does not require any preparation or fasting.

“For those over 30 years of age, it is advisable to have liver function tests during their regular health checkups,” he adds.

Albumin maintains the osmotic pressure of the bloodstream and prevents it from leaking out of the blood vessels into the tissues. Albumin levels indicate the protein synthesis function of the liver. “Within a month of liver damage, albumin levels start to drop,” explains Dr. Butt.

Dr. Nidoni adds that low albumin and total protein values ​​mean that the liver cannot produce proteins important for cell functions and vital functions such as the transport of essential molecules such as lipids through the bloodstream.

Dr. Bhatt also adds that globulin levels are also checked during liver function tests. Globulins are a group of proteins found in the blood that help fight infections and also help blood clot. Total albumin and globulin readings are used to calculate the albumin/globulin (A/G) ratio. If this ratio is above the permissible limit, there is a high chance of liver or kidney infection.

This test measures the amount of ALP in the blood. The ALP enzyme is found throughout the body but is most commonly found in the liver, bones, kidneys, and even the digestive tract. “It is an important enzyme for breaking down proteins. But if ALP levels are higher than normal it can indicate liver cancer, cirrhosis, hepatitis or even a blockage in the bile ducts,” explains Dr. Nidoni.

ALT is another enzyme found in the liver that helps convert protein into energy for liver cell function.

“If liver cells are damaged, ALT enzymes are released into the blood,” explains Dr. Butt. Dr. Nidoni emphasized that high ALT values ​​indicate either liver infections or obstruction of blood flow to the liver. It can also indicate liver cancer and cirrhosis.

AST is another liver enzyme for amino acid metabolism. If AST is found in the blood it indicates a liver complication or muscle damage, says Dr. Nidoni. High AST can mean hepatitis, cirrhosis, mononucleosis (a viral infection) or other liver diseases. It can also indicate heart complications or pancreatitis.

Bilirubin is a pigment produced by the breakdown of hemoglobin in the bile ducts. It is usually discharged in the bath. “A high level of bilirubin in your blood is a warning sign that your liver can’t clear enough bilirubin,” says Dr. Butt. That’s why when people have jaundice, bilirubin is high and indicates liver damage. High bilirubin levels can also be the result of other liver conditions including cancer or pancreatitis. There are two types of bilirubin – the indirect type, which travels in the blood to the liver, and the direct type, which undergoes changes in the liver and is excreted in the stool.

Decoding The Basic Liver Function Tests

GGT is an enzyme found in the liver, kidneys, and pancreas. “High GGT levels in the blood are due to alcohol abuse and also indicate damage to the bile ducts and fatty liver,” explains Dr. Butt.

A prothrombin time test is a blood test that measures how long it takes for blood to clot. An increase in PT may indicate liver damage, but it can also be elevated if you are on blood thinners.

Results are expressed as international normalized ratio (INR) and the normal range for this is between 0.9 and 1.1.

A liver function test involves a simple blood test but can check the levels of enzymes and proteins which are great indicators of liver health. People over the age of 30 should get regular updates on their liver status. These tests can often reveal other underlying kidney and stomach problems.

Liver function tests (LFT) are a group of blood tests that provide important information about the liver, including its ability to process chemicals and filter toxins from the body.

Interesting facts about the liver The liver is the largest internal organ in the human body. It performs more than 500 vital functions, including detoxification, metabolism, and nutrient storage. The liver can regenerate itself, allowing it to recover from certain types of damage. It produces bile, a substance necessary for the digestion and absorption of fat. The liver plays an important role in blood clotting by producing important proteins.

Summary To prepare for an LFT test, tell the doctor about the medication, take a blood sample, and follow up with the doctor to discuss the results.

High levels may indicate liver disease, blockage of the bile ducts, or other conditions that affect bilirubin metabolism. Low levels indicate anemia, hypothyroidism, liver disease
