Table of Contents • • • • • • • • • • • • It measures the levels of some enzymes and proteins present in the blood. The other terms for liver function tests are liver panel, liver profile hepatic function panel, and liver function panel. The purpose of the test is to check the overall condition of the liver. The liver is one of the essential body organs. It performs a variety of functions such as getting rid of contaminants from the blood, regulates blood clotting, stores essential vitamins and minerals, get rid of bacteria from the blood, creates factors that fight off infection, produces enzymes, proteins, cholesterols, and bile, helps maintains a balance between different hormones of the body, processes substances that could harm the body, and helps in regulating blood sugar level.

Picture Source: fattyliverguide.com What is checked during the liver function test/liver panel? #1 – Liver Proteins • Total Protein –It measures the total amount of protein present in the blood. The ideal level of total protein is 6.3 to 7.9 g/dL. • Albumin –It is a type of protein made in the liver. It is responsible for various bodily processes such as nourishing the tissues, stop the leakage of fluid out of the blood vessels, and transports essential substances throughout the body like vitamins, and hormones. Checking the level of albumin is a must as it assesses the capacity...

Liver function tests are blood tests that can be used to monitor the health of your liver. Ask the doctor what you need to do to prepare. In some cases you may need to avoid food or certain medications before the test. Depending on the test, either higher- or lower-than-typical levels of these enzymes or proteins can indicate a problem with your liver. Some of the reasons liver function tests may be performed include screening for diseases such as hepatitis, monitoring the side effects of your medications, and examining the severity of liver disease. In this article, we take a look at when you might need a liver function test, the different types of tests used, and how to interpret results. Share on Pinterest Medical Illustration by Bailey Mariner A liver function test is often recommended in the following situations: • to check for damage from liver infections, such as • to monitor the side effects of certain medications because some medications are known to affect the liver, including: • • • • • tuberculosis drugs • if you already have liver disease, to monitor the disease and how well a particular treatment is working • if you’re experiencing the symptoms of a liver disorder or have a family history of a liver disease, such as • if you have certain medical conditions, such as: • high triglycerides • • • • if you drink alcohol frequently • if you have Certain tests can reflect different aspects of liver function. For example, elevated Liver function tests are used to mea...

What are some of the most common liver tests? A series of special blood tests can often determine whether or not the liver is inflamed, injured, or functioning properly. These tests can also distinguish between acute and chronic liver disorders and between hepatitis (infection or inflammation of the liver) and cholestasis (disruption in the formation of or obstruction in the flow of bile). The most commonly performed blood tests include the following: Function tests • Serum bilirubin test. This test measures the levels of bilirubin in the blood. Bilirubin is made by the liver and is excreted in the bile. Elevated levels of bilirubin may indicate an obstruction of bile flow or a problem in the processing of bile by the liver. • Serum albumin test. This test is used to measure the level of albumin (a protein in the blood) andmay be usefulin the diagnosis of liver disease. Low levels of albumin may indicate the liver is not functioning properly. • International normalized ratio (INR), formally called prothrombin time (PT) test. This test measures how long it takes for blood to clot. Blood clotting needs vitamin K and a protein that is made by the liver. Prolonged clotting may indicate liver disease or other deficiencies in specific clotting factors. Liver enzymes • Serum alkaline phosphatase test. This test is used to measure the level of alkaline phosphatase (an enzyme) in the blood. Alkaline phosphatase is found in many tissues, with the highest concentrations in the liver,...

What Is a Liver Function Test? A Some of the tests look for enzymes that you’d find in your blood only when your Your liver does all kinds of work that’s crucial for your health. It helps break down food, clean your blood, make proteins, and store energy. If something goes wrong with it, you might have a number of symptoms, from yellow Why Are Liver Function Tests Done? You might have this test to check for a • Lack of appetite • • Weakness or feeling very • Yellowish • • Swelling in your belly (less common) Often, however, you don’t notice any symptoms. Your doctor may order a liver test if you’re more likely to have liver damage or disease, like if you: • Drink heavily or have an • Have a family member with liver disease • Are very • Take medicine that can harm your liver • Have The liver test can also help your doctor learn whether an illness is getting worse or how well treatment is working. Types of Tests and What They Measure There are a number of liver tests, with lots of complex names. Some common ones include: • Alanine transaminase (ALT) test. ALT is an • Alkaline phosphatase (ALP) test. ALP is an enzyme in your liver, bile ducts, and • Albumin and total protein test. Your liver makes two main proteins: albumin and globulin. Low levels might mean damage or disease. Keep in mind that your • Aspartate transaminase (AST) test. AST is another enzyme in your liver. High blood levels could be a sign of damage or disease. • Bilirubin test. Your body makes bilirubin when...

Overview Liver function tests are blood tests used to help diagnose and monitor liver disease or damage. The tests measure the levels of certain enzymes and proteins in your blood. Some of these tests measure how well the liver is performing its normal functions of producing protein and clearing bilirubin, a blood waste product. Other liver function tests measure enzymes that liver cells release in response to damage or disease. Why it's done Liver function tests can be used to: • Screen for liver infections, such as hepatitis • Monitor the progression of a disease, such as viral or alcoholic hepatitis, and determine how well a treatment is working • Measure the severity of a disease, particularly scarring of the liver (cirrhosis) • Monitor possible side effects of medications Liver function tests check the levels of certain enzymes and proteins in your blood. Levels that are higher or lower than normal can indicate liver problems. Some common liver function tests include: • Alanine transaminase (ALT). ALT is an enzyme found in the liver that helps convert proteins into energy for the liver cells. When the liver is damaged, ALT is released into the bloodstream and levels increase. • Aspartate transaminase (AST). AST is an enzyme that helps metabolize amino acids. Like ALT, AST is normally present in blood at low levels. An increase in AST levels may indicate liver damage, disease or muscle damage. • Alkaline phosphatase (ALP). ALP is an enzyme found in the liver and bone a...

Overview What are liver function tests? Liver function tests are What are the five primary liver function tests? The most common liver tests include: • Liver enzymes test. Your • Total protein test. A total protein test measures levels of protein in your blood. Your liver makes protein, and low protein levels may indicate that your liver isn’t functioning optimally. • Bilirubin test. Bilirubin is a waste product that your liver deposits in bile. • LDH test. Lactate dehydrogenase (LDH) is an enzyme found in many of your body’s tissues, including your liver. • Prothrombin Time (PT) test. This test measures how long it takes for a sample of your blood to clot, a process that involves proteins that your liver produces. These tests are all part of a routine blood panel called a When are tests done to check liver function? Your healthcare provider might want to check these values to screen you for possible hepatitis or other liver diseases. If they already know that you have What kinds of things can a liver panel tell you? Different values and ratios of different substances may tell your healthcare provider: • If you have liver inflammation (hepatitis). • Whether the inflammation is • Whether you have a problem in your liver itself or in your bile ducts. • If your liver function is impaired, and if so, how much. • If your bile flow is impaired, and if so, how much. • Whether your medications are affecting your liver, and if so, how much.
