Ask HN: How can I scan my DNA without sharing my biological data to anyone?
I want to know weaknesses of my body but I do not want governments to know that much about me. Any devices for doing the analysis at home and offline?
Then you need to perform a search for various genes or SNPs.
There are a few different assays to do this, but most require molecular biology reagents and special equipment.
You may even need to do some sequencing.
All of these services are provided by private companies but you can't be sure of the fate of your genetic information.
Doing it yourself is possible but would cost a few grand for bare essentials.
The only way to be sure. All other options are just facades for government.
