Introduction[edit | edit source]
Groups of blood tests performed to know the condition of a liver of a patient are known as liver function tests (LFT) or liver panel or hepatic function panel or hepatic panel.[1]
Components of Liver Function Tests[edit | edit source]
Alanine Transaminase (ALT); Normal value: 0-45 IU/L
Aspartate Transaminase (AST); Normal value: 0-35 IU/L[2] |
---|
Causes of raised transaminases:
|
Alkaline phosphatase (ALP); Normal value: 30–120 IU/l[2] |
---|
Causes of raised ALP:
|
Gammaglutamyl transferase (GGT); Normal value: 0 to 30 IU/L[2] |
---|
Causes of raised GGT:
|
Bilirubin; Normal value: 2 to 17 micromoles/L[2] |
---|
Causes of isolated hyperbilirubinemia:
|
Prothrombin time; Normal value: 10.9 to 12.5 seconds[2] |
---|
Causes of prolonged prothrombin time:
|
Albumin; Normal value: 40 to 60 g/L[2] |
---|
With progressive liver disease serum albumin levels fall, reflecting decreased synthesis. Albumin levels are dependant on a number of other factors such as the nutritional status, catabolism, hormonal factors, and urinary and gastrointestinal losses.[3] |
