Ethylglucuronide is a by-product of Phase 2 metabolism. So long as alcohol is in your system EtG is being produced. So your answer depends upon 1) your metabolic rate. 2) As a metabolite it is directly related to the amount of alcohol consumed. Although, that is confounded by the fact that 3) EtG is produced at individually variable rates. There is large inter-individual variation in all of the research to date. Within the group tested, with measured and balanced consumption, there is a variance of 800-1200%. Therefore the standard deviation renders averages meaningless. (Ex. One individual may have measurable EtG for 3 hours and another for 30+ after consuming the same amount of alcohol) Another factor is the 4) cut-off used by the testing agency. That varies from 0 (no threshhold) to 2000 ng/mL. (Many total abstinence programs use 100 although 500 is also common) There is no standardized, or even recommended, cutoff.
Given all the factors noted and based on the sparse scientific literature available, if you had a couple of drinks or even 3, you will probably be clear. If you had 6 or more you will probably register low presence (59 hrs). But in reality there is no way of telling.
Contrary to the averments of the testing labs, EtG testing is widely acknowledged in the scientific literature to be erratic and unreliable in determining actual consumption. Therefore even if you hadn't had a drink you should be worried.
