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
Pituitary signal to the thyroid — high TSH indicates the thyroid is being asked to produce more (hypothyroidism); low TSH indicates suppression (hyperthyroidism or exogenous thyroid). No direct peptide effects in stack peptides. Tirzepatide / Semaglutide can cause modest weight-loss-driven TSH shifts. KEY INTERACTIONS: biotin supplements above 5mg/day skew TSH assays — pause biotin 48-72h before draw. Acute illness suppresses TSH (non-thyroidal illness syndrome) — wait 2-4 weeks after recovery for accurate reading.
Have a recent TSH (thyroid-stimulating hormone) 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.
