Reference ranges
Optimal ranges are tighter than standard lab ranges and reflect functional-medicine targets, not the populations they were derived from. Reference bands depend on sex, age, and circumstance — Juno's lab analysis layers your profile context onto the printed range when you paste a value.
Peptide relevance
Primary copper-binding protein in plasma; 95%+ of plasma copper is bound to ceruloplasmin. Low ceruloplasmin with high plasma copper is the classic Wilson's disease pattern (rare). Low both = copper deficiency. Acute-phase reactant — rises with inflammation, so an elevated ceruloplasmin with normal copper may just reflect chronic inflammation. No direct peptide effects in common stacks. KEY INTERPRETATION: order alongside copper and zinc routinely when investigating mineral status; alone, ceruloplasmin is hard to interpret.
Have a recent Ceruloplasmin value?
Paste it on the lab analysis page. Juno reads your active stack + (if shared) your medications and conditions, and surfaces plausible contributors with citations. Doesn't diagnose.
