SNP Coverage Checker: Which DNA Test Includes Your SNP
Is that SNP in your DNA test?
Type any rsID, paste a list of rsIDs, or search a Genetic Lifehacks article title. You’ll see which DNA test files we checked include each variant, how sure we are, and — where it’s in a report — which Genetic Lifehacks articles explain it.

Caveats:
Your own file can still be missing the SNP. In a typical raw file, about 0.5–3% of positions are no-calls (shown as -- or 0 0). Some companies drop low-confidence calls from the download entirely, and chip versions change without notice.
Variants filled in statistically by a company or an imputation service aren’t counted here.
Use “Check my own file” to see if it is in your data. It runs in your browser, and your file is never uploaded.

SNP coverage results
Each row is a Genetic Lifehacks article. The percentages show how much of that article’s variant list was seen in the real test files we checked. Tick several articles to see which test covers your reading list best. This searches article titles only — not gene names (gene lookup is planned for a later version).

Your file stays on your device. It’s read by this page’s JavaScript, in your browser’s memory. This page makes no network requests, so you can disconnect from the internet before you choose a file. We only count which variant IDs are present. Your genotypes are never shown, saved, or sent anywhere. Closing the tab erases everything.

Your file’s coverage of Genetic Lifehacks articles
✔ Seen in a real file Found (k/n shown) in the real file(s) we checked for this test, Oct 2026 ✕ Not in files Absent from all files checked, where we have at least 2 files (3 for SelfDecode) ? Unknown Not seen in the only file we have, or a non-rs (i-)ID not yet mapped — we’d rather say unknown than guess
