Hi I Drank A Few Sips Of 4 Lokos Thursday

Hi I drank a few sips of 4 lokos thursday the 26th of november but knowing I had to take a ETG alcohol test the following week on thursday the 3rd I dumped it out due to being paranoid, by a few sips i mean not even enough to give me a buzz. Is it possible that alcohol will show up in my system and I will fail the test even though it was a week after I ingested alcohol? I am 21 weigh roughly 190 pounds and am about 5'10. From what I have researched the test can only detect consumption of alcohol after 80 hours in extreme cases. Will I pass the test?
