My proportions were 95% IndoEuropean and 5% East Asian, and the East Asian part surprised me. How reliable is the 5% part of the profile?
The 5% East Asian means you most likely share sequence identity with East Asians. From having run over 1,700 tests we know to expect a 3% error in your profile, almost all of it originating at the genotyping step. In rare cases where we have repeated analyses for a person over many runs, we have observed an error rate as high as 5%, but this is rare – 2-3% is the norm. Nonetheless, to be conservative, it is probably best for customers to take values less than 5% with a grain of salt. They may be significant, but they may not be. The confidence contours on your triangle plot show this to be the case – at these low levels, there is always overlap with 0% for this ancestry proportion.
