Hi I had one a lemon drop shot tonight (Friday) with a friend who came down to visit me but there's a chance I could get tested on Monday. Is one shot enough to register on the alcohol test?

The alcohol contained in one drink* should be metabolized in about 2 hours... no more than 4 hours. EtG would be detectable, in urine, for approximately 1 day (range 18-30 hr), based on current research.

*one standard drink, US = .06 oz pure ethanol
