you going to do the 23andme w/ the health screening too? I've been thinking about that not so much for the ancestry part as the health portion.
They are uncomfortably close to the government for me to do that. Further I doubt their accuracy. I just had genetic testing done for cancer alleles and Cedars Sinai drew blood stating initially saliva is not accurate enough.

ok, my question is, if they use your DNA to determine this, won't all DNA results be the same no matter how or where the sample is collected from or is there more to it than this? I don't understand the accuracy portion of it as I thought it would all be the same, but WTFDIK :)

edit: then another part of this is taking the data from say 23andme and downloading to this site;

These companies do not do a full sequencing. They look at SNPs (Single-nucleotide polymorphism), and there is still disagreement on which SNPs correlate to which disease and there is still research finding deviations of interest.

Sample collection, among other lab errors is a cause of laboratory inaccuracy, there is a far lower risk of contamination when blood is drawn in a professional lab vs saliva collection at home.
