Homocysteine (methylation / B-vitamin marker) — Waltham, MA.

Waltham, MA is the headquarters of the Massachusetts Medical Society, already confirmed via WebFetch to Wikipedia earlier this session -- which owns and publishes the New England Journal of Medicine, the exact journal this standard's foundational citation (Seshadri et al. 2002) appeared in. No honesty-limit caveat needed: the Society is the direct publisher of the citation's own journal. Distinct from the existing Framingham tile, which is built on the Framingham Study's own decades-long cohort site rather than the citation's publishing institution; also a genuinely separate reuse of Waltham/MMS from this session's earlier b12_folate_status and heart_rate_recovery tiles, each of which connected to a different standard's own distinct NEJM citation. Elevated homocysteine is a modifiable marker tying B-vitamin (folate, B12, B6) and methylation status to cardiovascular and cognitive aging, yet it is rarely on a standard panel.

$300 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.

Proof

Fasting plasma total homocysteine (µmol/L) with reference range, compared to the <10 / 10-15 / >15 bands for flagging only

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

How this work is done

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

Bring

• accredited-lab requisition (fasting tHcy)
• chain-of-custody label
• note on B-vitamin/supplement use and fasting status

Steps

1. 1. Arrange a fasting homocysteine draw through an accredited lab (fasting reduces diet-driven variation).
2. 2. Record current folate/B12/B6 supplement use and any known renal impairment (both shift tHcy).
3. 3. Capture total homocysteine (µmol/L) with the reference range.
4. 4. Place it against the <10 / 10-15 / >15 µmol/L bands for flagging only.
5. 5. Attach the report; log the value, fasting/supplement context, and band; sign it.

What counts as done

• Total homocysteine (µmol/L) from an accredited lab with reference range
• Confirmation the draw was fasting (and any B-vitamin supplement use noted)
• Result placed against the <10 / 10-15 / >15 µmol/L bands for flagging only

Proof is measured against these, not judged by taste.
