Alex writes to tell us about a DNA test kit comparison site called http://comparednakits.com/

This site reviews 20 different companies for genetic testing.

The areas it covers include how the DNA is collected, how many SNPs are tested (SNP is an acronym for single-nucleotide polymorphism and is a DNA sequence variation), for how long the DNA remains stored, what the site’s privacy policies are, whether they offer an option to match against relatives, whether a geographic analysis of the sample is made, and the pricing.

He cites examples of where the outcomes from these tests can sometimes be life-changing.

He explains that, for ancestry purposes, tests may be quite precise (and are still improving), but when it comes to health one needs to be careful, And, of course, there are also unscrupulous companies out there.

Once again, as always, no endorsement by BLHS either implied or intended here and…as ever…do your own research.
