The primary difference is that we're performing a clinical grade test that gives our patients actionable information. We only test for autosomal recessive disorders that will affect the health of your children. Unless you've been tested before, you don't know if you're a carrier. If both parents test positive for the same mutation then your child has a 25% chance of being born with the disease. This information allows you to make an informed decision about how to bring a healthy child into the world. (You have a few options once you have our test results -- in-vitro, adoption, or a normal pregnancy if the disease is manageable). 23andMe gives you SNP mutation results for many more genes that may or may not be associated with the disease that they report. They do a pretty good job of curation, but their SNPs do not guarantee your future disease status. Knowing that I have 2.3% higher odds of getting diabetes later in life is not going to meaningfully impact my day-to-day life, I already knew diabetes runs in my family, after all. 23andMe is great, don't get me wrong (many of us at Counsyl are 23andMe members, including myself), but they provide a different service for a different market. Our test requires a doctor's prescription and we include a free genetic counseling session (from our own licensed genetic counselors) for all patients. Finding out that you and your partner are carriers for a serious disease can be a big surprise and cause a lot of confusion and stress. We have great GCs to explain the effects of each disease and how they could manage it in a child, if they choose to have a normal pregnancy. We're more than just a SNP testing lab, we want to give you all of the information you need to have a healthy pregnancy. disclosure: I am a software developer at Counsyl, currently working on insurance automation and internal tools for our support staff.
