Additional Information
TMAO levels are lower in humans who follow a vegetarian or vegan diet than in omnivores. Because TMA and TMAO are naturally abundant in some fish, patients should fast overnight and refrain from consuming fish and other marine food items the day before the blood draw. Fasting for 10 to 12 hours is recommended.
