Home testing - faint lines - sticky thread request

[beach4fun]

First of all thanks for all the great info. You guys and girls are providing a valuable service here. First my suggestion/request. Could any of you experts (moderators etc.) who are allowed to post a sticky thread please start one and enlighten us with your knowledge on home testing kits and the various results and what they mean? Specifically, is there a guideline for the faintness of these testing lines? I have run the gamut from barely visible to solid yet lighter than the control line to identical to the control line. Specifically, are faint line test results flagged and sent in for further testing (GC/MS) or treated as a negative irregardless of how faint they are? If they are flagged and further tested, how faint must the line be for them to do this? I believe sec3 would be a good source for this info seeing that sec works for the industry but anyone who may know, please share your knowledge.
I also feel it would be a good idea to unlock this particular thread so everyone can compare notes and come up with a consensus on this and report test comparison results and maybe even rate the home testing products e.g. "my home test kit showed a solid line that was little fainter than the control line but I passed my test".

Now for a more personal question: From December to May, I smoked about 2 to 3 times a week. I smoked 2 or 3 times (appoximately 4 one hits total) during the month of May. On June 5 and 6, I smoked a one hit each day and on June 8 and 9 I smoked about 2 one hits each day and havent smoked since then. I will be going in for a test on June 26 or June 27 (approximately 17 to 18 days since I last smoked). I am a male in his 40's, 6' 2" tall, appoximately 185lbs (skinny but I got a some gut fat). I have been working out lifting weights (2X a week) and running 20 minutes (also about 2X a week) for the last 6 months. I took a test on my first morning void today (14 days since the last time I smoked) and I got a solid line however it is visibly a lighter shade than the control line. A couple of days earlier I tested myself after filling my bladder with 3 beers in the late afternoon and got 2 identical looking solid lines. I will be taking the real test monday or tuesday (June 26 or 27 its a 50ng test that will go to GC/SM if the initial results are positive). Will I pass the test?
Thanks in advance!
