Letters to the editor.

The olm — Proteus anguinus — is a cave-dwelling salamander of the Dinaric karst that lives, on average, a hundred years. Its tissues are quietly resilient; its inflammation does not smoulder; its body knows when to act and when to be still. We took its name because that biology — slow, attentive, regenerative — is the biology we are trying to read in you.

No. olm.health is a wellness instrument. We do not diagnose disease, we do not treat it, and we will tell you — kindly but firmly — when something belongs in a clinician's hands. We measure functional immune resilience and report it against your own baseline.

By a trained phlebotomist at one of our partner draw sites — a single venous sample, about fifteen minutes from arrival to departure. The functional immune assays we run require fresh whole blood and consistent handling, which centralised collection guarantees. A home-collection option is on our roadmap; we will not ship it before the data quality matches the chair-side draw.

Cytokines (IL-6, TNF-α, IL-1β, IFN-γ and the rest of the panel), high-sensitivity CRP, complement components, T-cell subsets including naive and exhausted populations, B-cell counts, NK cells, and a standardised functional response assay. Each reading is triple-measured.

Four issues a year. Quarterly. The dataset becomes itself across time — your seasons, your baseline, the patterns that emerge long before any symptoms.

You. The lab handling your sample. The clinical team composing your issue. No advertisers, no third-party brokers. Aggregated, de-identified data may inform research; you can opt out at any time without losing access to your readings.

Pricing is set with the founding readership. Leave your address on the cover and we will write with the details when your first issue is ready to be composed.

The companion app is in private beta — iOS first, web shortly after. Subscribers receive a link with their first issue.
