I have a question.
When testing for milk and soy validation of equipment, within the Canada, what level of milk and soy in the equipment is high enough to consider it contaminated?
The method I am using is ELISA, but I'm not sure what the minimum value in ppm to consider my validated equipment. Knowing that the sensitivity of ELISA is 0.05pp.
I'm sure someone is going to say 1 ppm but I just don't know where to find the documentation
