Drug Test coming up, some ???s

So I just replied to a thread with this but now realize it will probably have more replies its own thread (sorry have not used forums in a few years and am rusty).

The post and similarity of a test that i refer to in this thread can be seen at this link. [URL="http://boards.cannabis.com/drug-testing/181385-thc-cassette-test-results-faint-ghost-line.html#post2169505"]
Also mods if you want to delete my reply in that thread due to the unneeded repitition and maybe breaking rules please do, sorry for making you do extra work.

Anyway to get to it.

I have not smoked in over two weeks and when I was smoking had only smoked for about 3 weeks, although daily and quite heavily. Anyway I took this test tonight , although it was probably only my fourth piss of the day ( i know thats unhealthy, i had a weird day today and was not taking in much fluids). When I took the test tonight my line was slightly fainter and am wondering if this is a "ghost" line and what a "ghost" line is. (BTW I am about to use the search button for this topic, but the ghost question is not the only reason why I am posting)

This was some very dark pee as I have not drank much at all today (maybe 2 glasses of coca cola and 4 bottles of water through out the day), I also didnt even try to use the middle of my stream. I basically wanted to give myself the dirtiest test possible to see if i would pass that. I also had not urinated for about five hours, this was some real dark smelly pee...

So i guess my questions are:

1. Is a slightly fainter (but similar line) as posted before in the attached thread (top of the post) passable at a probation office drug testing facility?
----I will be getting tested in two days and am pretty certain that I could pass this test through some dilution method but i guess Im wondering if I am already passable and if i shouldnt bother loading some creatine tomorrow ( I know i should have already started that) and diluting the pee before the test with water and gatorade and coloring it with vitamin b2s.

----I have passed tests before in less amounts of clean time but I also exercised more and I feel that i had a slightly faster metabolism. I have also recently been around a lot of second hand smoke.
No matter what I will definately have diluted more than when I just tested myself

2. Are the levels tested at probations the same as levels tested on home drug test kits? and if so are POs warey(sp?) of faint and/or ghost lines or whatever is the equivalent.

3. Would you be real worried? I weigh about 160, 5'8" and am fairly skinny. This is an odd addition but I have recently been having upset stomachs and have pooped twice today with a few little turd nuggets but no real poops. I only add this because I have read a little about pooping also helping get rid of your thc and looking back on this past week I would say I have been pretty constipated or atleast pooping less often than usual.

4. What is a ghost line?

I appreciate your time in reading this and thank you all for any insight.
Sorry if this post was a little jumbled and unorganized as I have not participated on any forums for a few years now.

BTW. When i first took this test i was quite worried about how faint the line was as compared to the four other drugs that were tested and I knew I would pass.

Does THC normally show up more faint than other drug tests even for people who have not smoked for months?

I am also feeling a little bit better as i realized that a little bit of urine had actually stained on top of the lid right above the faint line and caused the line to look slightly fainter than it really was. Although stil from a distance of about two feet you can hardly see the line, but up close you can see that it is there. In previous self-tests the line has been faint but there has atleast been some part of it that was significantly darker than the rest.

Thanks again.
