I am a woman, 5'5", 125 punds. If I drink an ounce of vodka mixed with water on Friday night and another on Sunday night (early), will I test positive Monday in late afternoon? Thank you

The EtG created from one standard drink (US) is usually cleared in slightly less than 24 hours and EtG is not cumulative.
