Getting your genetic data deleted isn't easy and may not even be possible, writes Bloomberg's Kristen Brown.
She has sent her saliva to Ancestry.com, 23andMe, and Helix for analysis, and shared her genetic information with others, but writes at Bloomberg that she has become concerned with how much she has shared and decided to contact the genetic testing companies to have her information deleted and samples destroyed.
US federal law, she says, actually prevents labs from doing so. Clinical Laboratory Improvement Amendments regulations require labs to save some de-identified data as a quality control measure. That way, if there's an issue with testing, regulators can figure out what went wrong.
"It's a lesson we're destined to keep learning: Once you share something online, you can't really ever unshare it," Brown writes.
