Liver Function Test (LFT)

Concerned about how alcohol, medications, or other factors might be affecting your liver health, or experiencing symptoms that could indicate liver problems?

Overview

Your liver is like a sophisticated chemical processing plant working around the clock to keep you healthy, handling over 500 different jobs from filtering toxins out of your blood to producing the proteins your body needs to function. Think of liver function tests as a comprehensive inspection of this vital factory – they measure specific enzymes that leak into your bloodstream when liver cells are damaged, proteins that show how well your liver is manufacturing essential components, and waste products like bilirubin that can build up and cause yellowing of your skin and eyes if your liver isn't processing them properly.

What makes liver monitoring so important is that your liver is incredibly resilient and can keep working even when significantly damaged, often without causing obvious symptoms until problems become serious. These tests act like an early warning system, catching issues before you feel sick, whether they're caused by medications, infections, lifestyle factors like alcohol, or conditions like fatty liver disease. By getting a clear picture of how well your internal processing plant is running, you and your healthcare provider can address any concerns early and keep this hardworking organ functioning at its best.

Symptoms

You may benefit from this test if you experience:
Upper abdominal pain or discomfort Nausea in the morning Feeling tired all the time Annual physical exam High alcohol consumption Pale or clay-colored stools Difficulty controlling drinking or drug use Drug interactions concerns Binge drinking patterns Current or former smoking Medication interactions in elderly

Purpose

Essential for anyone taking medications that can affect the liver, regular alcohol consumers, individuals with hepatitis or family history of liver disease. Important for people with diabetes, obesity, or metabolic syndrome at risk for fatty liver disease. Valuable for routine health screening, monitoring liver health, and investigating symptoms like fatigue, abdominal pain, or jaundice.

How to prepare

Fasting for 8-12 hours recommended for most accurate results, particularly for bilirubin and protein measurements. Avoid alcohol for 24-48 hours before testing. Inform your healthcare provider about all medications and supplements as many can affect liver enzymes. Stay hydrated but avoid excessive water intake immediately before testing.

Understanding results

Normal ranges: ALT 10-40 U/L, AST 10-40 U/L, ALP 30-120 U/L, GGT <50 U/L (men), <35 U/L (women), Bilirubin 5-20 μmol/L, Albumin 35-50 g/L. Elevated enzymes may indicate liver cell damage, bile duct problems, or other liver conditions. Low albumin might suggest liver dysfunction, malnutrition, or protein loss. Results are interpreted together with symptoms and medical history.

After the test

Discuss any abnormal results with your healthcare provider immediately. Further testing may include hepatitis screening, liver ultrasound, or additional blood tests to identify specific causes. Treatment depends on underlying conditions and may include lifestyle changes, medication adjustments, or specific therapies. Regular monitoring may be required for chronic liver conditions.
