Reference ranges
Optimal
0.6 – 1.4 ratio
functional-medicine target
Standard
0.3 – 2 ratio
lab reference range
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
