Doctor/Practitioner
Certain lab tests may come back in the "normal" range. Reference ranges do not always mean "optimal." Patients may still experience symptoms in the "normal" range. It is important to speak with a qualified health practitioner regarding normal vs optimal.
Note
These lab tests can be purchased without a physician and drawn at a Quest Diagnostics location. A small draw fee of $ 8 will be applied at checkout. There are no other "hidden" fees unless noted on the lab test.
Currently, NY, NJ, and RI state laws prohibit direct-access testing. These lab tests cannot be conducted at lab locations within these states at this time.
Lab Test Category

TMAO (Trimethylamine N-Oxide)

Alternative Name(s)

Tri N-Oxide

Patient Preparation

Patients should fast overnight and refrain from consuming fish or other seafood the day before the blood draw to avoid false elevations in TMAO.

Clinical Significance

Gut microbes live symbiotically within the human digestive tract and play important roles in host defense, immunity, and nutrient processing and absorption. The diverse community is unique to each person and influenced by both acute and chronic dietary exposures to various food sources. Nutrients such as phosphatidylcholine (also known as lecithin), choline, and L-carnitine are abundant in animal-derived products such as red meat, egg yolk and full-fat dairy products. When consumed, these nutrients are processed by gut bacteria resulting in the release of various metabolites including TMA (trimethylamine) into the blood. TMA is then transported to the liver where it is converted into TMAO (trimethylamine N-oxide) which has been shown to regulate various physiological processes involved in the development of atherosclerosis.
