Biological variation versus analytical imprecision — does this still hold?

Solved Closed
Solved by j.dahlberg in post #2
Analytical imprecision: any measurement has an error margin. A small difference in consecutive tests is usually measurement noise, not a real change. Knowing the imprecision helps distinguish noise from signal.

The question in the title: Biological variation versus analytical imprecision — does this still hold? I will give what I have already checked below so nobody repeats it.

The question about Biological variation versus analytical imprecision that I actually want answered is the second one below. The first is context and I have kept it short.

Both are stated with units, and I have said what I already checked so that nobody repeats it.
