After drinking more than 16 non alcoholic beers 12 hours before a random urine test ,will you test positive for alcohol?

YOU will probibly fail the test...

Non-alcoholic beer isn't 100% alcohol free... and twelve or more will most certainly amount to a detectible quantity... if you don'tmanage to fail for dillution for drinking so much liquids to begin with.

Either will fail you...and a fail..is still a fail.

Non alcohol beer has alcohol in it, up to 0.5%. Read the fine print. Underage people cannot buy O'Douls.

Most likely you will fail due to alcohol... but also, that much drinking, can dilute system, to point of failure also.
