Find out how well your liver works with a liver function test

What is a liver function test?

Liver function tests, commonly known as LFTs, analyze the levels of enzymes, proteins, and other substances produced by the liver in your blood. These assessments provide important information for healthcare providers about the health and functionality of your liver. A liver panel typically evaluates several substances simultaneously in the same blood sample. Cost of a liver function test This varies depending on the diagnostic lab you visit.

What does a liver function test involve?

Liver function tests assess the levels of enzymes and proteins in your blood, which indicate possible liver problems when they differ from normal levels. This test provides a diagnostic evaluation as well as information about underlying problems. Key measurements include:

• Alanine transaminase (ALT): This enzyme, also called SGPT, is found primarily in the liver and plays a key role in converting protein into energy for liver cells. Elevated levels of ALT in the bloodstream often indicate liver damage, potentially resulting from a variety of conditions such as fatty liver disease, hepatitis or alcohol-induced liver injury.
• Alkaline Phosphatase (ALP): This is an enzyme found in the liver and bones that plays a key role in the breakdown of proteins. High ALP levels may indicate liver damage or problems, such as a blocked bile duct or certain bone disorders like Paget’s disease.
• Aspartate transaminase (AST): AST, or SGOT, is an enzyme that aids in the breakdown of amino acids. While present in various organs, including the liver and muscles, increased AST levels usually indicate liver damage or disease, but may also point to muscle injury or heart problems.
• Albumin and Total Protein: Albumin is a protein synthesized by the liver that is essential for a variety of body functions including maintaining fluid balance and transporting hormones and other substances. Low levels of albumin and total protein in the blood may indicate liver damage or disease, as well as gastrointestinal or kidney-related conditions that affect protein synthesis.
• Gamma-glutamyltransferase (GGT): GGT, an enzyme present in the blood, increases when the liver or bile ducts are damaged. Although it is not specific for liver disease, increased levels of GGT can provide valuable information when interpreted with other liver function tests.
• bilirubin: It is a byproduct of red blood cell breakdown, which is processed by the liver and excreted in the stool. Elevated bilirubin levels may indicate liver dysfunction, such as hepatitis or bile duct obstruction. Additionally, conditions such as certain types of anemia or hepatic duct obstruction may also contribute to increased bilirubin levels.
• Prothrombin time (PT): This measures the time it takes for blood to clot, which reflects the liver’s function in synthesizing clotting factors. An increased PT may indicate liver damage or impaired liver function, but it is necessary to consider other factors such as medication use, especially blood-thinning drugs such as warfarin, which can affect clotting time.
• L-lactate dehydrogenase (LD): It is an enzyme found primarily in the liver and when its levels are increased it can indicate liver damage. However, it is important to note that an increase in LD can also be due to other conditions such as muscle injury or certain cancers, which require a comprehensive diagnostic approach.

Why is a liver function test done?

Liver function tests are mainly performed for the following purposes:

• assessing whether symptoms could be caused by liver disease or damage
• Determining the severity of the diagnosed liver disease
• Monitoring the progression of liver disease or evaluating the efficacy of treatment
• Detecting potential adverse effects of drugs that affect liver function

What do abnormal liver function test results indicate?

While this blood test can provide valuable information, it cannot provide a definitive diagnosis for a specific liver condition. However, it can guide your healthcare provider and help eliminate other possible causes. In addition, diagnostic procedures such as imaging tests, specific virus blood tests, or liver biopsy may be necessary to confirm the diagnosis. Possible diagnoses may include:

• Toxic hepatitis
• Fatty Liver Disease
• Autoimmune hepatitis
• hemochromatosis
• Viral hepatitis (A, B, or C)
• wilson’s disease
• Primary Biliary Cholangitis (PBC)
• Alpha-1 Antitrypsin Deficiency
• liver cancer
• Cirrhosis

Overall, liver function tests provide a straightforward way for you and your healthcare provider to assess the health of your liver. Whether checking for potential liver disease or monitoring the effects of medication or treatment, a small blood sample can provide important information.

Although liver function tests alone may not be enough for a diagnosis, the information gained from these tests informs the next steps in your healthcare journey.
