A diluted urine drug test is one where the sample was diluted. It happens in two ways--you drank too much water to make yourself pee (DOT's standard says drink no more than 40 ounces of water), or you put water in your sample after you peed it out.

A negative diluted test says "no drugs in this sample passed the test thresholds, but it was diluted so there MIGHT be drugs in here." Basically, a diluted negative is a test failure.
