You can bet on it, that is how accurate it is.

At a reading of 693 you are in the range that should be assumed to be due to environmental sources of alcohol rather than drinking. Furthermore, the EtG test can never show that you drank. It cannot differentiate between alcohol that is consumed as a beverage or alcohol from food, fruit, inhalation of alcohol fumes or endogenous production of ethanol. The test should never be used as a sole means to determine drinking. (see Ethylglucuronide)

The Substance Abuse and Mental Health Services Administration (SAMHSA) part of HHS and establishes and regulates all federally mandated drug testing programs issued a specific Advisory on EtG testing in 2006... (see SAMHSA Advisory, still valid)

Since the initial advisory it has now been determined that EtG can be created by a combination of foods you may have eaten, containing yeast and sugar and that EtG is unstable in your urine sample. The sample may either degrade or manufacture EtG post collection.

The key is the low EtG content. Any reading under 3500 should be questioned and thoroughly investigated. Unfortunately, those administering the tests usually have no specific training in interpreation.

Does your printout provide a reading for EtS and/or creatinine and/or specific gravity?
