Purser Wellness reference range
This is Purser Wellness’s adult reference. Your own lab may print a different interval. Some entries need more context than a single number.
- Unit
- µg/dL
- Male
- 73-129
- Female
- 77-206
How to read this marker
Estrogen, pregnancy, inflammation, liver function, and ceruloplasmin affect values.
The wider testing context
A blood level may not tell you everything about what is happening in tissues. Fasting, recent supplements, inflammation, sample handling, and the test method may affect a result.
Using this range
These are starting ranges for adults who are not pregnant, unless this page says otherwise. Your lab may use a different range. Compare the units, sample, and collection details with your own report. Medicines and health history also matter. Ask your clinician what your result means for you.
A question to bring to your visit
How does the Copper, serum range here compare with my lab’s range, and what else matters for me?
Compare with your report
Before discussing a result, keep these details together:
- Your result and its units
- The range printed by your own lab
- When the sample was collected, and the sample type or method if shown
- Medicines, supplements, and changes in your health that may matter
A number on this page cannot diagnose a condition or choose a treatment for you. Your clinician can help put it in context.
MAKE SENSE OF YOUR COPPER RESULTS
Non-ceruloplasmin copper calculator
Use your zinc, total copper, and ceruloplasmin blood results to estimate NCC and the copper:zinc ratio.
How this estimate works
This uses the formula in Dr. Purser’s handout: NCC (µg/dL) = total copper (µg/dL) − 3 × ceruloplasmin (mg/dL). NCC percentage = NCC ÷ total copper × 100. Copper:zinc ratio = total copper ÷ zinc, using the same units.
Calculated NCC is an estimate. Test methods and how much copper is bound to ceruloplasmin can affect it. It differs from a direct lab measurement of labile or exchangeable copper. It cannot diagnose fibromyalgia or copper toxicity, or choose treatment for you. Read about the limits of calculated NCC at Mayo Clinic Laboratories ↗
