The Liver Function Test (LFT) is a simple blood test that checks how well your liver is working. It measures six key enzymes and bilirubin levels—ALT, AST, ALP, GGT, total bilirubin and direct bilirubin—to flag possible liver stress or disease, which can be important for anyone taking medication, drinking alcohol, or managing metabolic health. This test is ideal for adults who need a baseline liver check or ongoing monitoring, and it comes with a venous blood draw and a GP‑led consultation, all for £215.
About this treatment
A Liver Function Test (LFT) provides a snapshot of hepatic health by quantifying six specific biomarkers in a single venous blood sample. The panel includes ALT (Alanine Aminotransferase) and AST (Aspartate Aminotransferase), enzymes that rise when liver cells are damaged; ALP (Alkaline Phosphatase) and GGT (Gamma‑Glutamyl Transferase), which reflect bile‑duct function and alcohol‑related stress; and both total and direct bilirubin, which indicate how…

Biomarkers tested
6An enzyme found in the liver, bones, kidneys, and digestive system. Elevated ALP can indicate bile duct obstruction, liver disease, or bone disorders. It's normally higher in children and during pregnancy due to bone growth.
A liver enzyme that helps convert proteins into energy. ALT is found primarily in the liver, making it a highly specific marker for liver damage. Elevated levels may indicate hepatitis, fatty liver disease, or medication-related liver injury.
An enzyme found in the liver, heart, and muscles. While less liver-specific than ALT, elevated AST can indicate liver damage, heart attack, or muscle injury. The AST/ALT ratio helps distinguish between different liver conditions.
Bilirubin is a substance produced during the normal breakdown of red blood cells. High levels can lead to jaundice and indicate liver or bile duct problems.
Elevated levels may indicate a liver or bile duct blockage.
A liver enzyme sensitive to alcohol use and bile duct problems. GGT is often the first liver enzyme to rise when bile ducts are blocked. Combined with ALP, it helps determine whether elevated ALP is from liver or bone.
