Thanks, Halo. I really appreciate the feedback.

I've only tried and passed the one take home 50ng/ml test. My thinking is if I pass one I should pass them all, but I guess depending on how muck fluid I drink, results will vary.

I wasn't aware that 20 ng/ml tests were sold on Amazon, unfortunately for me it's too late to order one to use prior to tomorrow. Is anyone aware of a location that sells the 20 ng/ml tests?? If so i'll go buy one right now!

In regards to the specimen validation strips, are they sold at Walgreens or CVS? I'll do some research and go purchase a couple to test myself tonight and tomorrow morning.

Lastly, subbing is not completely out of the picture. However, it makes you very nervous if you have to go through x-rays and a physical first... I've got the rest of the night to think things over.

Any new input is still greatly appreciated. I'll be certain to post my discoveries and results as I go..

Thanks!
