This is the BEST way to look at what your Copper is really doing.
Is it getting into the cells, or building up in other places? Let’s see!
Non-Ceruloplasmin Copper Calculator
Calculate NCC in Seconds
Enter zinc, copper, and ceruloplasmin exactly as they appear on a lab report.
The calculator converts units, calculates the copper:zinc ratio, and highlights the percent
of non-ceruloplasmin-bound copper.
Lab Inputs
Use the unit dropdowns to match the lab report. The app normalizes everything to µg/dL before calculating.

Formula used:
Copper:Zinc Ratio = Total Copper ÷ Zinc
Copper Bound to Ceruloplasmin = Ceruloplasmin × 0.003
NCC = Total Copper − Copper Bound to Ceruloplasmin
NCC % = NCC ÷ Total Copper × 100
