Understanding Alanine Aminotransferase (ALT)

Alanine Aminotransferase (ALT) is a key biomarker in blood tests that an enzyme found in the liver, used to assess liver health.

What is Alanine Aminotransferase?

An enzyme found in the liver, used to assess liver health.

Normal Range

Low < 7 U/L
Normal 7 - 55 U/L
High > 55 U/L

The normal Alanine Aminotransferase range is between 7.0 and 55.0 U/L.

High Alanine Aminotransferase Levels (Above 55.0 U/L)

Causes of High Alanine Aminotransferase

High ALT suggests liver inflammation due to alcohol, fatty liver disease, hepatitis, or medication toxicity. Reducing alcohol, improving diet, and addressing liver issues can help lower ALT.

Health Effects of High Alanine Aminotransferase

Chronically high ALT indicates liver inflammation, potentially leading to cirrhosis, liver failure, and metabolic disturbances.

Low Alanine Aminotransferase Levels (Below 7.0 U/L)

Causes of Low Alanine Aminotransferase

Low ALT is uncommon but may be linked to chronic liver disease, malnutrition, or vitamin B6 deficiency. Ensuring proper liver function and maintaining a nutrient-rich diet can help.

Health Effects of Low Alanine Aminotransferase

Low ALT is generally not a concern unless accompanied by signs of liver dysfunction or metabolic issues.

Treatment and Management

For High Alanine Aminotransferase

  • Medical evaluation to determine the underlying cause
  • Lifestyle modifications as recommended by your healthcare provider
  • Regular monitoring of Alanine Aminotransferase levels
  • Follow-up testing as needed

For Low Alanine Aminotransferase

  • Medical evaluation to identify the root cause
  • Appropriate supplementation if recommended
  • Dietary changes as advised
  • Regular monitoring and follow-up

When to See a Doctor

Consult your healthcare provider if:

  • Your Alanine Aminotransferase levels are consistently outside the normal range
  • You experience symptoms associated with abnormal Alanine Aminotransferase levels
  • You have risk factors for conditions affecting Alanine Aminotransferase levels
  • You’re taking medications that may affect Alanine Aminotransferase levels

Prevention

  • Regular health check-ups
  • Balanced diet
  • Regular exercise
  • Stress management
  • Adequate sleep
  • Avoiding known triggers
