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
Hemoglobin breakdown product; cleared by the liver. Elevation can be hepatic (liver dysfunction), pre-hepatic (hemolysis — increased RBC breakdown), or post-hepatic (biliary obstruction). Gilbert's syndrome (benign genetic variant affecting ~5-10% of population) elevates total bilirubin mildly (1.0-2.5 mg/dL) without disease — easily mistaken for liver problems. Fasting and dehydration also acutely raise total bilirubin in Gilbert's carriers. No direct peptide effects in common stacks. AAS (NOT peptides, common co-use) can elevate bilirubin in users developing cholestatic injury. KEY INTERPRETATION: if total bilirubin is elevated, order direct (conjugated) bilirubin to fractionate — mostly indirect bilirubin suggests Gilbert's or hemolysis; mostly direct suggests hepatic or biliary cause.
Have a recent Bilirubin, total 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.
