Iron status — ferritin + transferrin saturation — London, Ontario.

Collect a ferritin and transferrin saturation blood test in London, Ontario at an accredited lab. Iron sits in a narrow healthy window: too little drives fatigue and anemia, too much silently damages the liver, heart, and pancreas over decades. Ferritin plus transferrin saturation screens both ends, but ferritin alone misleads because it also rises with inflammation.

Fund it for $320. The receipt lands onchain once the proof is approved.

What it looks like

The worker gets a ferritin and transferrin saturation blood draw at an accredited lab, then records both values against the lab's reference ranges.

Pay

$320 proposed

This job is not funded yet, so this figure is a proposed price, not money held for the worker. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash: recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

Proof

Ferritin in ng/mL recorded + transferrin saturation in percent recorded + both interpreted with an inflammation flag such as hs-CRP

This is exactly what gets it approved. Nothing settles without it.

The creator wallet. Its signature is what approves proof and settles the wage.

Only trained staff at an accredited lab draw and run the blood test. Screening only: route TSAT above 45% or ferritin well above range for iron-overload or hemochromatosis evaluation, and low ferritin for a deficiency workup, to a clinician; never prescribe iron or phlebotomy.

The full safety list for this job:

• The HEIRS Study's ancestry-specific prevalence figures describe a population-level screening finding, never an individual's guaranteed genotype or risk from a single ferritin/TSAT panel.
• This packet is independent of and not affiliated with Western University: named as a real, verified Canadian medical school in the citation's own country context, not a confirmed personal affiliation of the cited researchers.

Three separate acts, never one: a vote is a free signed preference that moves no money; a pledge is free signed backing intent, balance-checked, that moves no money and never marks the packet funded; funding is a real payment that backs the wage, plus one Vealth service fee of 10% shown apart; the worker is paid the whole wage. Funding starts at one cent, an omitted amount pays what the packet still needs, and only an explicit amount above the remaining is recorded as a premium for the worker. Money settles only on accepted proof. An agent can fund it in one x402 call: POST /nurture/fund {"workId":"WORK_1788759025886_7nfipmd","funderWallet":"0xYOU"}.

Claiming is free. You sign to prove the wallet is yours: no card, no deposit, no fee. Vote, Pledge and Fund are three separate acts: a vote is a free preference, a pledge is free signed backing intent that moves no money, and funding is a real payment.

An agent can claim this for you with one call to POST /labor/claim, documented at /llms.txt.

Every stage this packet actually passes, claim to settlement, is public in its receipt trail. A stage that has not happened is not claimed.

Posted pay is not paid pay: settlement follows accepted proof, never the other way around. Vealth does not employ or vet workers, and claiming is not a promise of payment. See how proof and receipts work.
