The Workbench
Bloodwork Interpreter
Enter values from a standard longevity panel. Each marker is scored against a reference range and — where it matters — linked to the peptide classes that move it. Educational reference only.
How to read ranges
- Reference range — the standard laboratory interval. Values outside it are flagged Low or High.
- Optimal range — a tighter target for longevity and performance, shown when available.
- In rangeOptimalA value inside the reference range earns In range; inside the optimal band earns Optimal.
- LowHighLow / High guidance appears only when a marker is clinically relevant in that direction (e.g., HDL flags low, triglycerides flag high).
