Using the NCC Formula

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.

Zinc Required for copper:zinc ratio

µg/dL µmol/L g/L mg/dL mg/L µg/L ng/mL

Total Copper Required for all NCC calculations

µg/dL µmol/L g/L mg/dL mg/L µg/L ng/mL

Ceruloplasmin Usually mg/dL or g/L

mg/dL g/L µg/dL mg/L µg/L ng/mL

Calculate NCC Reset

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
