The health predispositions part of the test is crucial. It provides insight into your chances of developing certain health conditions, like type 2 diabetes, late-onset Alzheimer’s disease, and celiac disease. You can also figure things out like your genetic weight, muscle composition, and alcohol flush reaction. It all starts when you receive a DNA collection kit in the mail. Spit in the provided tube, register your kit with the barcode, and mail the saliva sample back to the lab with the prepaid package. You get your results back in 5-6 weeks. You can upgrade the basic service with a 23andMe+ Premium membership. The membership bundle usually costs $229, but on Prime Day, you get it for $109 – a savings of $120. The benefits of the membership include exclusive access to DNA insights around heart health, pharmacogenetics or how your prescriptions interact with your genetics, and 30 more personalized genetic reports than the regular kit. 23andMe takes data privacy seriously, encrypting, protecting, and storing your data at your discretion.
