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

Framingham, MA is the actual site of the foundational cohort behind this standard: the Framingham Study (begun 1948) followed 1,092 dementia-free adults a median 8 years and found each 1-SD rise in homocysteine carried a 1.4x (dementia) to 1.8x (Alzheimer's) adjusted relative risk (Seshadri S, et al. N Engl J Med. 2002;346(7):476-483), with levels above 14 µmol/L nearly doubling Alzheimer's risk. This library's own ApoB standard already carries a Framingham tile for a different landmark finding from the same cohort (the 1961 cholesterol-risk-factor paper) -- homocysteine is a separate, later Framingham contribution, real local science built in this same town on the same running cohort.

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.
