Understanding Low ALT (Alanine Aminotransferase) Levels

ALT is an enzyme primarily found in liver cells. Low ALT levels (below 7 U/L) are relatively uncommon and may indicate certain health conditions or advanced liver disease.

What is Considered Low?

An ALT level below 7 U/L is considered low. While low ALT is generally not a major concern, it may indicate:

  • Vitamin B6 deficiency
  • Chronic liver disease
  • Advanced cirrhosis
  • Malnutrition
  • Frailty syndrome

  • Ascites
  • Spider angiomas
  • Palmar erythema

Systemic Symptoms

  • Malnutrition signs
  • Poor wound healing
  • Reduced muscle mass
  • Decreased energy
  • General weakness

Causes

  • Severe illness

Diagnosis

The diagnosis of low ALT involves:

  1. Medical history review
  2. Physical examination
  3. Blood tests including:
    • Complete liver panel
