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
Most abundant plasma protein; reflects liver synthesis capacity AND systemic inflammation (negative acute-phase reactant — falls during inflammation). Low albumin suggests advanced liver disease, kidney protein loss (nephrotic syndrome), severe malnutrition, or chronic inflammation. Used in the free testosterone calculation (Vermeulen equation) and free-cortisol estimation. No direct peptide effects in common stacks. KEY CAVEAT: dehydration falsely elevates albumin; over-hydration falsely lowers. Healthy adult range is narrower than the standard lab range suggests — values <4.0 g/dL in an otherwise healthy adult warrant a look at protein intake or chronic inflammation. Long-term low-calorie dieting (common in peptide users on cuts) can subtly lower albumin.
Have a recent Albumin, serum 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.
