Has anyone had any issues with the rapid response 2.0 test strips? I test for Fentanyl and sometimes I think the parameters for the amount is very low and I don’t believe the strips. I wanted to ask for those who test which ones do you use and what are the instructions for the recommended amount of product to dilute in water. And how much water are they saying.

Thanks for the help and happy nods 🤙🏼
