I am trying to validate a new method for substances with LMR and I would like to calculate the CCα and de CCβ. However, I keep funding different ways of doing it.
According to the Decision 2002/657 states “The corresponding concentration at the value of the decision limit plus 1,64 times the standard deviation of the within-laboratory reproducibility equals the detection capability “ How do I calculated the standard deviation of the within-laboratory reproducibility?? Because I have prepared six replicates of samples at three different concentration 0.5*MRL,1*MRL and 1.5*MRL.
Any comment or help will be very useful,
Thanks in advance
