Liver Function Test (LFT).
Checks how well your liver is working, using a group of markers rather than a single number. Useful for general health screening, investigating symptoms, or monitoring medication that can affect the liver.
Several markers, one clearer picture.
A liver function test measures several substances made or processed by the liver, including proteins, bilirubin, and a group of liver enzymes. Looking at these together gives a fuller picture of liver health than any single marker alone.
Markers included: albumin, total protein, globulin, total bilirubin, alanine transaminase (ALT), aspartate aminotransferase (AST), gamma glutamyl transferase (GGT), alkaline phosphatase (ALP).
This test is commonly used for general health screening, investigating symptoms such as fatigue or abdominal discomfort, or monitoring the liver while taking certain medications, including some used for cholesterol or weight management.
