I used a First Check Home Drug Test and received a very faint pink line, will I be ok for a drug screening? - first check home drug test faint line
The test says that means no detectable negative pink line. I try for a research study to screen. I think I'm right?

Yes, you will be fine. When a test is presented as a negative that will always be negative .... not have the same positive results. Sometimes a positive test result may be negative, but a negative is always negative.
