I’m not totally sure that is how measurement error works, and the 1ug/dl choice is rather arbitrary (looking at your previous post, isn’t it already uncorrected for measurement error?). In any case, I think bringing in additional complications like measurement error (itself just one of several things that could be reducing power in your standard social psychology experiment) makes the core points about statistical power harder to understand.
