The TMAO (Trimethylamine N-oxide) analysis is a test used to measure the levels of TMAO in the blood, a compound produced in the body as a result of metabolizing certain foods, such as red meat and egg yolks. TMAO is an important marker for assessing health risks associated with cardiovascular diseases, as studies suggest a link between elevated TMAO levels and an increased risk of these conditions. This test helps guide medical decisions and lifestyle changes, such as dietary modifications, contributing to improved overall health and a reduction in risks related to metabolism.
