Hi John,

❝ Yes but we usually only have one number (don't present SD or range) on the CofAs (test and ref)

Correct. You could ask the lab for the accuracy/precision of the method. In my previous post I only wanted to wave the warning flag concerning overly optimistic assumptions like “Hey, the difference is just 2%, let’s estimate the sample size based on a ratio of 98%”…

I’m not a pessimist,
I’m just a well informed optimist. (José Saramago)
