Unfortunately, the 23andMe $99 DNA kit doesn't offer any health screening information anymore. It's just an ancestry service now, after getting nailed by the FDA for failing to prove the reliability of their claims about their "medical devices" which these kits are now considered. And looking around for some more services is kind of confusing. Searching by genetic tests, DNA screening kits, etc. results in articles discussing the FDA's recent crackdown. I say this not to dispute your point, but I was seriously curious about getting a peak into my health through one of these tests and now you can't seem to do it.
We did one that costs like $2400 because we got it free from one of Deb's reps. That one was about screening for Down's and the like. Interestingly enough, they could tell us what chromosomes they found but refused to sex the fetus because they hadn't been approved for that by the FDA.
