Q. What specific parameters are measured in a typical liver function test (LFT) panel?
Doctor Answer is medically reviewed by SecondMedic medical review team.
In a typical liver function test (LFT) panel, several key parameters are measured to assess the health and function of the liver. These parameters include:
1. Alanine Aminotransferase (ALT): This enzyme is found in liver cells. Elevated ALT levels can indicate liver damage or disease, such as hepatitis.
2. Aspartate Aminotransferase (AST): Another enzyme found in liver cells, elevated AST levels may suggest liver injury, although it's also found in other organs like the heart and muscles.
3. Alkaline Phosphatase (ALP): This enzyme is present in the bile ducts and bone. Elevated ALP levels can indicate liver or bone disorders, or issues with bile flow.
4. Total Bilirubin: Bilirubin is a breakdown product of red blood cells. Elevated levels can indicate liver disease or problems with bile excretion.
5. Albumin: This is a protein produced by the liver. Low levels can indicate liver damage or disease affecting protein production.
6. Total Protein: Measures the total amount of protein in the blood, which can be affected by liver function.
7. Gamma-Glutamyl Transferase (GGT): Elevated GGT levels can indicate liver or bile duct problems, or excessive alcohol consumption.
These parameters provide valuable insights into liver health and can help diagnose various liver conditions such as hepatitis, fatty liver disease, cirrhosis, or liver tumors.
Understanding the results of these tests requires interpretation by a healthcare provider, who can assess the overall picture and recommend further investigations if necessary. Remember, individual results may vary, so it's essential to discuss any concerns with your healthcare professional for personalized advice and treatment.
