The body odor and halitosis community has a great interest in Trimethylaminuria, given that it is the only generally accepted systemic body odor by the orthodox medical system. Regular readers will be aware there are very few labs who test for TMAU, and that those labs generally have their own protocol which varies from the others.

The urine test at the labs can vary in instructions, in the equipment used for testing, and in interpretation of the results. Below is a table of the known information about each TMAU urine test lab. If you know that any information is incorrect we would be happy to be informed.

One benefit of knowing the various differences is that since the results are usually the same for each lab, you can compare your results against their reference ranges.

MEBO Research is attempting to construct and update a table of the various procedures that labs use for TMAU testing. The latest version can be seen in this PDF table. If there are any errors, or anyone has new information on TMAU test labs, feel free to let us know.
