HBRI doing TMAU urine (phenotype) testing again

The HBRI website says that it is accepting urine samples for TMAU phenotype testing again. This has been confirmed by email. HBRI is the institute of Dr John Cashman, who has a long history in TMAU/FMO3 research.

They test for trimethylamine-oxide in the urine, as well as trimethylamine. The test is conducted in-house and the cost is $400. A sample must be sent frozen overnight.

This means there are now 3 known TMAU urine testing sites in the USA ; HBRI in San Diego, UC Denver, and Arkansas Children's Hospital.

UC Denver and HBRI both test for TMA and TMA-oxide in their urine test, with Denver costing $250 and HBRI costing $400. But with HBRI, you can test direct without the need for a Dr requesting the test.

We keep a note of all the known TMAU test labs in the world on our MeBO TMAU page :
