Pre-employment drug screen options - what would you choose?

Hello and thanks for what seems to be the best, most factually-based set of drug testing threads on the web! I've spent the last day and a half reading through these and wanted to ask the experts here for their opinion about the following situation.

My husband has an upcoming pre-employment drug screen. There's no way he has time to clear out naturally so we're left with the following options:

1. Synthetic urine (QuickFix) - good shelf life, easy to transport, but have heard that it's not 100%, even the Canadian version with the added uric acid
2. Dehydrated real urine (TestClear) - haven't heard that much about it which doesn't fill me with the greatest sense of confidence, but it is supposedly "real urine"
3. My urine - I haven't smoked in months, no drugs at all, just lots of prenatal vitamins as I am 6 mo pregnant

I've been reading that they won't check for gender or HCG so we're leaning toward option 3, but I wanted to get a firm opinion. I'm still tempted to pick up some non-pregnant urine, but that's probably just me being paranoid since everything I've read here seems to indicate that this isn't necessary. This job is a great opportunity for us all, so I really want to make sure this goes smoothly!

Thanks for your input!
