If the error is proportional to the measurement - can't you just take the log to make it additive again?

Hmm, it's not clear to me what the benefit of that would be in terms of information (a transformation). It's univariate data, it's been a bit since I looked at it but a histogram showed readings were lognormal / weibull / gamma distributed (point is asymmetric, right-skewed), I believe.

In terms of inference, it's kind of mind-bending to think of a "population" of blood and each person having a specific variation.
