First of all, thank you for your consideration about this question.

I've been working on development of in-vitro diagnostic medical device as research engineer since 2013. Especially, my major is to develop kit using colorimetric method, immunoassay and electrochemistry method.

Btw, I am wondering how could I remove the positive signal at the zero concentration when using colorimetric method. In other words, sometimes I face difficulties because color reaction occurs at zero concentration (There is no substrate I want to analyse).

Please kindly share your advice.
