Extremely useful study, thanks. They graphed the relationship between ceruloplasmin and serum copper for a very large patient population, and it's a nearly linear relationship. I immediately see my data point falls outside the graphed relationship, so that definitely gets my curiosity up. I have serum copper at 18.08 umol/L and ceruloplasmin at 187.9 mg/L. The relationship is in their Figure 1.
