Description
The Liver Function Test is a comprehensive panel that reveals how well your liver is working, detecting damage and disease often before any symptoms appear.
About the Liver Function Test (LFT)
An LFT measures a group of enzymes and proteins — including ALT, AST, ALP, bilirubin and albumin — that reflect the health of your liver. Abnormal results can point to inflammation, fatty liver, hepatitis, alcohol-related damage or the effects of certain medications. Because the liver often functions silently until significantly affected, this panel is an important part of routine screening and of monitoring known liver conditions.
Preparation and turnaround
A venous blood sample is required; fasting is sometimes requested, and our team will confirm when you book. The test takes only a few minutes and results are usually available within one working day. Abnormal results are best reviewed with a doctor, who may recommend imaging or hepatitis screening to establish the cause.
Frequently asked questions
Do I need to fast for an LFT?
Fasting is sometimes requested, particularly if the LFT is combined with glucose or a lipid profile. We will confirm the preparation needed when you book.
What can abnormal liver enzymes indicate?
Raised enzymes can reflect fatty liver, inflammation, hepatitis, alcohol-related changes or medication effects. Further tests help identify the specific cause.
Can the liver be damaged without symptoms?
Yes. The liver often works normally until significantly affected, which is why blood testing is valuable for early detection.
