Ceruloplasmin
The protein that carries roughly 90% of the copper in your blood. Measured next to total copper it lets us calculate the free, unbound fraction — the copper that is not safely carried, and the part that damages tissue.
What the numbers mean
These are the ranges BioForge works to. They are not the same as a lab's reference range, which is built from the general population rather than from people who feel well.
What moves Ceruloplasmin
Rises with inflammation of any kind, with estrogen, oral contraceptives and pregnancy, and falls in Wilson disease and severe copper deficiency. Because it rises on its own it can make free copper read falsely low — which is why we draw hs-CRP alongside it and ask about estrogen before interpreting either. Free copper = total copper minus 3.15 times ceruloplasmin; under 15 mcg/dL is normal, over 25 gets investigated.
