Waiting to get tested/TMAU

I have contacted Dr. Preti and the health center in CO about testing, from what I understand they are both having delays and will be longer than first thought. It seems like most people that have tested positive and  tried cleansing and antibiotics have had some success. I'm just curious if there is anyone that has not seen any result?

Has anyone tested negative for TMAU and used antibiotics with good results?

Thanks
