Questions about home test, should i waterload for the real test?

[Deige]

I took an at-home test w/ morning pee today to make sure i was ready for my probation drug test tomorrow.

I tested negative with a very faint red line.

However i'm more afraid of the cutoffs concentrations for this home test vs the probation test. The manual in the home test says the cutoffs are:

Immunoassay: 50 ng/ml
GC/MS: 15 ng/ml

It doesn't say which one it is, it just has that info. I'm guessing the cutoff is 50 ng/ml, do proby drug tests have the same cutoff? What is GC/MS?

My biggest concern is whether or not waterload according to the sticky tomorrow. If im already gonna pass.... i dont want to risk pissing off my PO with a dilute result.

You probation test should have the same cutoff levels as your home test. I would drink a 32oz gatorade and void twice before you take the drug screen.
