Not sure exactly what DNA tests you want or need? No problem. Helix, a company founded with support from Illumina, the leading maker of DNA sequencing equipment, lets you sequence and save your DNA once, and decide what you want to learn from it only when and if you choose to. Send in a spit sample, and for $80, Helix sequences your exome and stores the data in the cloud. When you’re ready, go to the DNA App store, and choose from one or more third-party reports covering ancestry, health, fitness, and more. Reports range from about $30 to $200, with partners including the Mayo Clinic and Geisinger health system. Helix added more than 20 new products and services to its online store in 2017, and will launch several new health tests in 2018, while continuing to grow health and fitness categories, as well.
