Liver Function Test (LFT) evaluates how well your liver is working by measuring enzymes, proteins, and substances produced or processed by the liver. It helps detect liver damage, disease, and monitor liver health.
Your liver performs over 500 vital functions. With rising rates of fatty liver disease due to modern lifestyle, LFT is crucial for early detection of liver problems before symptoms appear. Essential for those taking medications that can affect liver function.
Increasingly important due to lifestyle factors like alcohol consumption, processed foods, obesity, and exposure to environmental toxins. Critical for early detection of non-alcoholic fatty liver disease, now common in urban populations.
Fasting for 8-12 hours may be required depending on the specific tests included. Avoid alcohol for 24 hours before the test. Follow your doctor's instructions about medications.
Elevated liver enzymes (ALT, AST) may indicate liver damage. Abnormal bilirubin, albumin, or protein levels can suggest various liver conditions. Results must be interpreted by a healthcare provider.
ALT: 7-56 U/L, AST: 10-40 U/L, Bilirubin: 0.2-1.2 mg/dL, Albumin: 3.5-5.0 g/dL
Medications, alcohol, viral infections, fatty liver disease, autoimmune conditions, and certain supplements can elevate liver enzymes.
Mild elevations may be temporary and benign, but require follow-up testing and evaluation by a healthcare provider to determine the cause.
Avoid alcohol, follow fasting instructions, and inform your doctor about all medications and supplements you're taking.
