Okay, I did two with two different samples of urine with the same result. Now that I know it wasn't the dilution doing it, I'll try again. (Have to wait till I have to pee haha) Checked the expiration and it's January 2012 on all of em. None of the reviews on Amazon mention this problem, and almost all have had excellent results with them so I doubt it's the strips themselves unless its a bad batch. I guess there's probably a reason they send you 10 for 7 bucks, bound to be a few bad apples in there. I'll let you know what happens on my next couple.
Sakeller24 Reviewed by Sakeller24 on . At home test.. Dilution Okay so I wanted a little reassurance that the dilution method would work to get me below the threshold so I ordered these at home drug tests.. Amazon.com: THC Marijuana Dip Strip Test Pack of 10: Health & Personal Care Basically one line means positive and two means negative; however, I'm getting no lines repeatedly. I'm sure I'm doing the test right. It says no lines means the test was invalid but gives no further explanation. Do you think maybe my urine is too dilute to register even Rating: 5
