TMAO (Trimethylamine N-Oxide)
### A Trimethylamine N-oxide (TMAO) lab test measures the level of TMAO in the blood, a compound produced by gut bacteria during the digestion of certain nutrients, such as choline, lecithin, and carnitine, which are found in red meat, eggs, and dairy products. Elevated TMAO levels are associated with an increased risk of cardiovascular diseases, including heart attack, stroke, and atherosclerosis. This test is used to assess cardiovascular risk by evaluating TMAO levels as a marker of gut microbiome activity and its influence on heart health.
