How much Advil can make you fail a drug test?

It wouldn't make you fail a test, drug tests check for opiates such as heroin or vicodin or oxycottin.....benzo's such as valium, Xanax, or lexapro.....and amphetamines, or methamphetamine's.....advil is ibuprofen which is an NSAID pain reliever and does not show on a drug test
