Hello, this is Dr. David. I am reviewing your question now and will be with you momentarily.

Expert:  Dr. David replied 4 months ago.

are you male or female? how old are you?

you can get false positive in ETG in your urine if you have a urinary tract infection.

you should ask them to check your urine for bacteria and UTI.

here are some articles about that

References regarding the value of using EtS as well as EtG testing. (It costs the lab about 50 cents more to test for both analytes.)

I am a physician in a PHP program, have been sober since the 4/1, and received the letter today where they state that my etg level is 11,800ng/mL, and ets 1710 ng/ml. It is very frustrating as there was no alcohol use.
Expert:  Dr. David replied 4 months ago.

well, I have given you some articles that show a UTI can cause ETG in the urine.

you have to ask them to test your urine for bacteria and signs of UTI.

let me know if you have other questions.
