Sorry, another post, as I read a response from BT, who said that the intensity of the line is not really a factor.

I have gotten a line (fainter than control) every time I have tested with these strips, so this is a good thing?

Interested about the DOT question above, still, however. I was told that there is a physical, and a test at the hospital locally, and that they send out the samples in batches, so it might be a couple of days. What does that info tell me (between the lines)?
