Understanding Lab Tests for Favism
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Favism is a potentially life-threatening condition that occurs when individuals with glucose-6-phosphate dehydrogenase (G6PD) deficiency consume fava beans or are exposed to certain other triggers. This hereditary enzyme deficiency can cause sudden destruction of red blood cells, leading to severe anemia, jaundice, and kidney problems.
Recommended Test
Glucose-6-Phosphate Dehydrogenase Quantitative
This blood test directly measures the level of G6PD enzyme in red blood cells. A deficiency in this enzyme is the underlying cause of favism. Testing can identify individuals at risk before they experience a potentially dangerous hemolytic episode from consuming fava beans or other triggers.

Diagnosing G6PD Deficiency to Prevent Favism
Since favism is a direct result of G6PD deficiency, identifying this genetic condition through blood testing is crucial for prevention. Individuals with this deficiency need to avoid specific triggers, including fava beans, certain medications, and other substances that can cause red blood cell breakdown.
Why Early Detection Matters
G6PD deficiency affects millions of people worldwide, particularly those of Mediterranean, African, and Asian descent. Early detection through blood testing allows individuals to take preventive measures and avoid triggers that could cause severe complications including hemolytic anemia and organ damage.
