The Heaven Bio Sync kit for the kitchen counter: a blood-testing machine, Bio Sync Draw, and a supplement dispenser, Bio Sync Dose, working with the Heaven Halo ring. Both plug into an ordinary wall socket and connect to the Heaven Health app. This dossier covers the concept, the rotatable 3D models, the full parts list, how it connects to the app, and a build plan in order for a contract manufacturer.
People cannot safely put in their own IV line at home, and no regulator will allow it. The fingertip rests on the analyser's light ring, where a single-use sampler cartridge with a retracting lancet fills the sealed disc, targeting about 50 µL. That is enough for a small panel on a microfluidic disc, but not for a full hospital panel.
Theranos failed by claiming hundreds of tests from one drop of blood. Version 1 measures about 8 markers using methods that already run reliably on point-of-care analysers. Larger panels go by post or through the blood-centre booking the app already offers.
A blood test used at home is an in-vitro diagnostic. In the US that means FDA 510(k) or De Novo clearance for home (over-the-counter) use, backed by a lay-user study; home-use clearance makes the test CLIA-waived. In the EU it is an IVDR self-test with a notified body, and in the UK it goes through the MHRA (UKCA). That process, not the hardware, sets the timeline. Expect several years for a new analyser. Licensing a proven point-of-care analyser shortens it a lot.
Dose numbers come from fixed rules with hard safety ceilings, and the member approves every change. Anything flagged, such as starting iron, needs a clinician's sign-off. Luna can explain a plan, but Luna never sets a dose.

Each marker is chosen because a proven point-of-care method exists for it. Roche's cobas b 101 runs lipids, HbA1c and CRP on a spinning disc, and Abaxis's Piccolo uses rotors with dried reagent beads. That supports the disc design, but every assay still needs its own validation.
| Marker | Method on the disc | Stage | What it can change |
|---|---|---|---|
| 25-OH vitamin D | Fluorescence immunoassay (reader D8) | v1 | Vitamin D3 dose, up to the ceiling |
| Ferritin | Fluorescence immunoassay | v1 | Iron: clinician gate never started automatically; read alongside CRP |
| Total cholesterol · HDL · triglycerides | Enzymatic colour change, absorbance (D7). LDL is calculated | v1 | Omega-3 (EPA+DHA) suggestion. Out-of-range lipids trigger a doctor referral, not a supplement |
| HbA1c · glucose | Immunoassay / enzymatic absorbance | v1 | No supplement change. Flags and referral only |
| CRP | Immunoturbidimetric absorbance | v1 | Context only: a high CRP freezes ferritin-driven changes |
| Vitamin B12 · TSH | Fluorescence immunoassay | v2 | B12 dose. TSH: referral only |
| Omega-3 index · magnesium · zinc · full blood count | Dried blood spot card posted to a partner lab, or a blood-centre booking | mail-in | Arrives as a normal lab report through the existing upload path |

The analyser's result lands in the same blood-report format the app already uses for uploaded lab PDFs. Trends, biomarker history and Luna's explanations work without new result screens. What's new is pairing, the guided test and today's dose.

Integrity rules the firmware and backend enforce. If any QC check fails, results is empty and the app shows "Retest" with the reason. There are no partial results and no estimated values. The app never shows a marker the disc didn't measure. A used disc serial is rejected by both the tag and the server. The app bills a test only once a result has passed QC.
Supplements come in fixed strengths, so "balancing" means choosing how many units of each canister to dispense. The engine works to the adult tolerable upper intake levels, always uses the stricter of the US NIH Office of Dietary Supplements and EFSA figures (EFSA's are lower for zinc, magnesium, B6, selenium and copper, and EFSA's 2024 safe level of 40 mg for iron), and dispenses automatically only up to half of that limit.
| Nutrient | Adult upper limit (stricter of US NIH ODS and EFSA) | Automatic ceiling | Rule |
|---|---|---|---|
| Vitamin D3 | 100 µg (4,000 IU) | 50 µg (2,000 IU) | Above that needs a clinician. Retest vitamin D after 8–12 weeks before any further change |
| Iron | 40 mg (EFSA) | 0 mg | clinician gate never started automatically. Low ferritin with a high CRP means "see a doctor" |
| Zinc | 25 mg (EFSA) | 12 mg | Pair with copper if the course runs past 8 weeks |
| Magnesium (supplemental) | 250 mg (EFSA) | 125 mg | Blocked if the profile lists kidney disease |
| Vitamin B6 | 12 mg (EFSA) | 6 mg | Uses the stricter EFSA figure |
| Selenium | 255 µg (EFSA) | 100 µg | Never automatic if a multivitamin canister already contains it |
| Vitamin A (preformed) | 3,000 µg | not dispensed | Excluded: pregnancy risk |
| Copper | 5 mg (EFSA) | 2 mg | Only alongside a long zinc course, and never with a copper-containing multivitamin |
| Omega-3 (EPA+DHA) | 5 g (FDA) | 2 g | Blocked with anticoagulants unless a clinician co-signs |
Also enforced: each nutrient changes at most once per retest cycle. A result outside the plausible range prompts a retest, not a dose change. Pregnancy, anticoagulants, kidney disease and listed prescription drugs all route the plan to a clinician. Totals are summed across every canister, including multivitamins, before any ceiling is checked. Canisters are identified by NFC, so a misplaced canister is refused rather than dispensed.
