Please keep YOU to one topic, you already basically asked the same thing in your other thread and got an answer:

BT stated: "Home tests, being assays themselves, function on the same principles as the assays used by the labs. Therefore, neither are more reliable than the other."

A test, is a test, is a test.
webdox Reviewed by webdox on . First Check / Home Drug Test This is the one I picked up at Walmart and it is for MJ only. (First Check / Home Drug Test (1 Drug Tested / Marijuana) I was just wondering if anyone has had any experience with this kit and if they thought it was pretty accurate. It says 99% accurate. Pretty cool though because after I get the results in 5 min. I can ship it off to their lab and they will do a GC/MS test for free because of the purchase. Their results won't be ready for 5 to 7 days so that really does me no good since my Rating: 5
