Q. How do liver function tests (LFT) help in diagnosing liver diseases?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Liver function tests (LFT) play a crucial role in diagnosing liver diseases by providing valuable insights into the health and functioning of the liver. These tests measure various enzymes, proteins, and substances in the blood that indicate how well the liver is working.
One key marker in LFT is alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Elevated levels of ALT and AST in the blood may indicate liver damage, such as from hepatitis or fatty liver disease.
Another important parameter measured is bilirubin, which can help identify conditions like jaundice or liver inflammation. High bilirubin levels may suggest a problem with the liver's ability to process and excrete bilirubin.
LFT also includes tests for albumin and total protein levels. Low levels of these proteins can indicate chronic liver disease or malnutrition.
Moreover, LFT measures alkaline phosphatase (ALP) levels, which can be elevated in conditions affecting bile ducts or bones.
By analyzing these markers together, doctors can assess overall liver function and detect a range of liver diseases, including hepatitis, cirrhosis, and liver cancer.
Interpreting LFT results requires expertise and may involve further testing or imaging to confirm a diagnosis. Understanding LFT results helps doctors develop tailored treatment plans and monitor the progression of liver diseases.
Regular liver function testing is recommended for individuals with risk factors such as alcohol abuse, obesity, viral hepatitis, or family history of liver disease.
In summary, liver function tests are instrumental in diagnosing liver diseases by assessing liver enzyme levels, bilirubin, proteins, and other indicators. These tests provide valuable information that guides treatment decisions and disease management. Early detection through LFT can lead to timely interventions and improved outcomes for patients with liver conditions.
