A few years ago, Nebula Genomics would let anyone take its DNA test at no charge — in exchange for answering a number of health questions, and then allowing the company to share customers’ DNA information with genetic researchers.
But that’s no longer the case. Currently, a test from Nebula Genomics costs 649,00 US$  — plus an ongoing subscription fee.
However, if you’ve already had your DNA tested by either 23andMe or AncestryDNA, you can download your raw data from those companies, upload it to the Nebula Genomics website, and then receive a free DNA report.
This report is probably not equivalent in scope to the report you'd get from using Nebula Genomics for your test. Most likely it’s just intended to give you a taste of what you’d get from a paid Nebula Genomics report and subscription.
Customers who’ve already bought and registered a Nebula Genomics test kit aren’t able to upload their raw data from 23andMe or AncestryDNA.
