In brief: Timing/volume

The 1/2 life or time required for 1/2 the alcohol to leave a normal system is about 4 hours.
By 8 hrs 3/4 is gone, 12 hrs 7/8 is gone, etc.. The larger the volume or strength consumed the more likely it would be detected by a test if it were done. Any past damage to the liver would decrease the amount eliminated/hr.
