Lab Results Explainer

Understand your liver function tests. Simple explanations of what each test means and what abnormal values indicate.

Select a Test

ALT (Alanine Aminotransferase)

Normal Range:

7-56 U/L (may vary by lab)

What is ALT?

An enzyme found primarily in liver cells. When liver cells are damaged, ALT leaks into the bloodstream.

Why Does It Matter?

ALT is very specific to the liver. High levels usually indicate liver damage or inflammation.

What If It's Abnormal?

Elevated ALT suggests liver injury from fatty liver disease, hepatitis, cirrhosis, or other conditions.

What to do: Consult your doctor if ALT is elevated. Lifestyle changes and monitoring are usually recommended.

Understanding Your Liver Panel

Common Patterns in MASLD

Mild Fatty Liver

Slightly elevated ALT/AST, normal bilirubin and albumin

Moderate Disease

More elevated ALT/AST, possibly elevated GGT

Advanced/Cirrhosis

High AST/ALT ratio, elevated bilirubin, low albumin, low platelets

When to See a Doctor

•Any abnormal liver test result
•ALT or AST more than 2-3 times normal
•Elevated bilirubin (yellowing of skin/eyes)
•Low albumin or platelets
•Worsening trends in repeated tests

Tips for Better Results

✓ Get fasting blood tests for most accurate results
✓ Keep a record of your test results over time
