Ben Greenfield interviews Heather (an MD/PhD) about Talking20, an at‑home dried blood spot testing service that uses mass spectrometry to run many quantitative blood tests from a few drops of fingerprick blood mailed to the lab. Heather explains the method (3-mm punches from dried cards), global mail-in workflow (no cold chain needed), an initial panel of ~17 tests being readied, pricing options (a $99 'pick five' deal and gold-card subscriptions of 24 or 36 cards), and a limited-time 10% promo code (BENSTEST). Use cases include frequent monitoring for athletes, food/alcohol response experiments, hormone and vitamin tracking, and citizen-science crowd studies. Heather emphasizes this augments—not replaces—physician care.
