About GuideToGenetics

Who we are

The site is authored by the GuideToGenetics editorial team. Articles are published under that team byline rather than under a fabricated individual reviewer credential. When we work with a credentialed genetic counselor on specific health-interpretation content, the counselor is named in the Reviewed by field on the relevant article. As of September 2026 that work has not yet started, and no article on the site is marked as medically reviewed.

The project exists because consumer DNA test marketing rarely answers the question buyers actually have ("which test for me?") and because the corporate landscape changed enough in 2024 and 2025 (the 23andMe Chapter 11, the TTAM data transfer, the Nebula Genomics shutdown) that older buyer guides are not safe to rely on. We rebuild the comparisons from first principles against the live merchant pages and the public record.

How we work

Sourcing. Every factual health claim is checked against a primary source: FDA authorizations, CDC publications, peer-reviewed literature, and professional society statements from the American College of Medical Genetics (ACMG) and the National Society of Genetic Counselors (NSGC). Competing affiliate blogs are not primary sources and do not appear in our citation list.

Pricing. Every price, turnaround window, and database size on the site is pulled from a central products.json file that we refresh against the live merchant pages. The "as of early 2026" caveat appears on volatile data because the numbers change. The cost calculator and product cards both show the last-researched date.

Affiliate relationships. The site earns affiliate commissions on some links. Every outbound link to a merchant routes through a tracked /go/[slug] redirect, and every page containing one carries an FTC-compliant disclosure above the fold. Editorial picks are made before any affiliate link is added. We never accept payment in exchange for ranking. The DNA Testing Privacy Checklist contains no affiliate links by deliberate design, because a privacy checklist that is quietly selling tests reads as the exact conflict of interest it warns against.

Out of scope. We help readers choose and understand a DNA test. We do not interpret individual results, predict future health, or tell anyone what an APOE, BRCA, or carrier finding means for them. Those conversations belong with a board-certified genetic counselor or a doctor. The NSGC maintains a counselor directory at findageneticcounselor.nsgc.org.

What we will not do

We will not write fear-based copy designed to scare readers into buying a test. We will not interpret a specific genetic result for a specific reader, even on request, even in friendly DMs. We will not fabricate a medical reviewer to give the site clinical authority it has not earned. If those constraints feel restrictive, they are the reason the site continues to be useful on a topic that has a lot of marketing and not enough honesty.
