What This Test Measures
This test includes measurements of enzymes and markers that reflect liver function, such as: - **Liver enzymes** (e.g., alanine aminotransferase, aspartate aminotransferase) that indicate liver cell damage. - **Other liver-related substances** (e.g., bilirubin, albumin) that assess liver synthesis and bile flow.
Why It’s Done
Your healthcare provider may order this test if you have symptoms like jaundice (yellowing skin/eyes), fatigue, abdominal pain, or if you have a history of liver disease, alcohol use, or exposure to toxins.
Common Causes of Abnormal Results
Abnormal results may signal conditions like hepatitis (viral, alcoholic), fatty liver disease, cirrhosis, or other liver disorders. Elevated enzymes often appear early in liver damage, while bilirubin or albumin changes may indicate more advanced issues.
What to Expect Before the Test
No special preparation is needed unless instructed. You may be asked to fast for 8–12 hours before drawing blood, but this depends on the specific enzymes being tested. Avoid alcohol for 24 hours before testing if it’s related to liver enzymes.
Reference range
Adult: 10-40 U/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
