Hi. Good day.

 

I am currently working on our trend analysis report from last year and would like to establish an alert limit for each parameter (from the swab tests) based on the data I acquired.

 

 

Maybe anyone knows the formula in establishing the alert limit.

 

Thank you very much.

Hi anielee,

 

This is a highly subjective topic. Any evaluation will depend on the context, eg Product/Process/micro.specifics.

 

Can have a look at this "study" which is slightly old although there are some "updates" within its subsequent comments -
