intermediate work · Accredited lab / clinic draw, Baltimore, MD

Red cell distribution width (RDW aging marker) — Baltimore.

Fund it for $180. Proof lands onchain when it's done.

$180 proposed

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. 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.

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.

What the work involves

Baltimore, MD is home to Luigi Ferrucci, senior author of this standard's foundational meta-analysis (Patel KV, et al. J Gerontol A Biol Sci Med Sci. 2010;65(3):258-265) and, since 2002, Director of the National Institute on Aging's Baltimore Longitudinal Study of Aging (BLSA) -- one of the longest-running human-aging studies in the world, run from this city. RDW comes free on any CBC yet is rarely read as what it is: a robust, cheap predictor of all-cause mortality even in people without existing age-related disease. Offered where a career of this aging-biomarker research is directed.

Proof
RDW (%) from a CBC with reference range, compared for flagging only alongside hemoglobin/MCV context

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

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

How this work is done

A documented method, so this packet comes out the same whoever does it.

Bring

  • accredited-lab requisition (CBC with differential)
  • chain-of-custody label
  • note on known anemia, recent transfusion, or nutrient deficiency

Steps

  1. 1. Arrange a standard CBC through an accredited lab (RDW is reported as part of it).
  2. 2. Record any known anemia, recent blood loss/transfusion, or nutrient (iron/B12/folate) issues.
  3. 3. Capture RDW (%) plus hemoglobin and MCV from the same CBC with reference ranges.
  4. 4. Place RDW against the ~11.5-14.5% reference, read alongside hemoglobin/MCV, for flagging only.
  5. 5. Attach the report; log RDW with the hemoglobin/MCV context and band; sign it.

What counts as done

  • RDW (%) from an accredited-lab CBC with reference range
  • Hemoglobin and MCV from the same CBC recorded for context (anemia screen)
  • RDW placed against the ~11.5-14.5% reference for flagging only

Proof is measured against these, not judged by taste.

The money and the proof

What is promised, and what is not.

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. 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_1788244214982_6782h4p","funderWallet":"0xYOU"}.

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.
