Why This Test Matters

Your liver produces and releases many proteins and enzymes into your bloodstream. When the liver is injured or diseased, some of these proteins may leak into the blood at higher levels. This test looks for signs of these proteins, which can indicate liver problems like inflammation, infection, or scarring.

What to Expect Before the Test

No special preparation is usually needed. You may have a small needle inserted into your arm to draw blood. If you’re on blood thinners or have a history of bleeding issues, let your doctor know before the test.

Common Causes of Abnormal Results

Elevated levels of these markers can occur with liver diseases such as hepatitis, cirrhosis, fatty liver, or alcohol-related liver damage. They may also appear with other conditions like heart problems, infections, or certain medications.

What the Results Mean

While this test doesn’t provide a single number range, doctors compare your results to your baseline or other tests to determine if your liver function is affected. High levels may prompt further testing or follow-up.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What triggers this test?
Your doctor may order this test if you have symptoms like unexplained fatigue, jaundice (yellowing of skin/eyes), abdominal pain, or if they suspect liver disease based on your medical history, medications, or other test results.
How often should I get this test?
Frequency depends on your health. If you have a known liver condition, your doctor may recommend regular testing. If this is a one-time screening, it may not be repeated unless symptoms or other test results suggest further evaluation.
Can lifestyle changes affect this test?
Yes—alcohol consumption, diet (especially high-fat foods), medications, and infections can impact liver enzymes. Avoiding alcohol, eating a balanced diet, and following your doctor’s advice can help support liver health.
