Your blood test reads chemistry.
We read your immune system.
Today's most advanced biomarker testing reads about 100 markers. Antygen reads millions of antibody signals from one drop of blood, the record of everything your immune system has fought, and everything it's quietly attacking.
Everything we test for, in one sample.
There is no test menu to pick from. Every sample runs against the whole array: 124 named readouts across 18 families, drawn from 21,000+ protein targets, every time.
A layer nothing else reads.
A research-grade
array.
Every sample runs on a research-grade human proteome array of 21,000+ proteins, plus a full viral-exposure phage panel, processed at a CLIA-certified partner lab. Research-grade instrumentation, not a consumer approximation of it.
21,000+ human proteins on every chip
Benchmarked against a research reference cohort
Six domains, 120+ named readouts, one sample.
Every kit runs the full panel. Nothing is tiered, nothing is upsold, and nothing here is a separate test you have to choose.

Why this compoundsEvery person carries 50 to 400 IgG autoantibody hits. Over half have never been described.
Each one is a potential drug target, a biomarker, or a directly actionable health insight.
From your kitchen table to 21,000 proteins.
Every other advanced panel depends on a draw site near you. Antygen's collection method travels by post, so the coverage map is the postal service.
One drop, at home
A finger-prick dried blood spot. No clinic, no phlebotomist. Mail it back in the prepaid kit.
Screened on a proteome array
Your sample runs across 21,000+ human proteins plus a full viral-exposure panel.
Read at a partner lab
A CLIA-certified partner lab processes your repertoire on research-grade instrumentation.
Your immune map
Millions of signals become a clear, trackable profile in your private portal.
Normal B12. Neurological decline. One antibody explained it.
A patient's serum B12 looked perfectly normal, yet they were deteriorating. The cause: an autoantibody blocking the CD320 receptor that ferries B12 into cells. Invisible to standard labs. Visible in the antibody repertoire.
Frequently asked questions.
Those services read your blood chemistry, metabolites, hormones, cholesterol, roughly 100 biomarkers. Antygen reads your antibody repertoire: millions of immune signals across 21,000+ proteins. It's a complementary, deeper layer, not a replacement for a metabolic panel.
A private portal mapping your anti-pathogen defenses, exposure history, any destructive autoantibodies, allergic profile, and immune biomarkers you can track over time, with plain-language context.
Antygen is an early-access research and wellness profile, not a diagnostic device. It surfaces immune signals worth discussing with your clinician, it doesn't diagnose disease on its own.
A simple finger-prick dried blood spot at home. No clinic visit, no phlebotomist. Everything you need ships in the kit, and return postage is prepaid.
Samples are processed at a CLIA-certified partner lab on a research-grade human proteome array of 21,000+ proteins, plus a viral-exposure phage panel. It is research-grade instrumentation used in autoantibody research, not a consumer approximation.
