A member asked:
I just tested +for etg on a ua; i havent had any alcohol. i have a bad bladder infection and my ua showed very high ketones. can this cause a false +?
A doctor has provided 1 answer
See below: Ethyl glucuronide (EtG) test is very sensitive and specific test and a strong indicator of alcohol ingestion within the previous 3-5 days. UTI or high ketones will not cause a false positive EtG. Unintentional exposure from certain OTC medications, personal hygiene products (e.g. mouthwash, hand sanitizers) or foods prepared or flavored with alcohol can cause a "low level" positive test.
