Okay, so I understand that even a faint line is considered to be negative, but how open to interpretation is that? What is a "faint" to one lab tech be considered "preliminary positive" to another?

I'm curious as to what people (especially those with experience) know about this. I took a DOT test and the morning before I took a test with first void and there was a faint line... then the day of my test I used my third void of the day for my actual DOT test, but then next void I tested with a drug test Walgreen one and the line was so faint. I can try to add it, but the blur is horrible, so you might not see it well.

Now it did have a faint pink line. But how objective are the testers at Quest who do these initial preliminary screenings? I'm just concerned what is pass with the instructions would be a fail by that tech's opinion.

Are they trained that every line, no matter how faint, is done as a negative (passing)?
