I saw this recently on 23andMe’s blog – DNA Testing Fills in Gaps for Adult Adoptees: https://blog.23andme.com/ancestry-reports/dna-testing-for-adoptees/ and thought it was a good post for this week’s DNA Saturdays post. It’s a longer article, but thought this portion was a good sample.
For adoptees and people who find an Non-Parent(s) Event (NPE), I recommend testing directly with each company as opposed to testing with some companies and transferring results to other companies. I give the same advice for those who want to do apple to apple comparisons who don’t have adoptee or NPE issues. In this chart: https://isogg.org/wiki/Autosomal_SNP_comparison_chart#Autosomal_SNP, it shows how few SNPs are compared between different companies. In my case, I tested with the v3 chip on 23andMe years ago. In comparing my v3 chip results to their v5 chip, I had a lot fewer SNPs to compare – bit over 177K. With other v3 chip testers, I had bit over 930K SNPs in common. That’s a sizeable difference when trying to compare relationships with different chips from the same company. I purchased the upgrade to v5 chip set during the Amazon Prime sale where 23andMe lowered the price for an upgrade by $20. If they hadn’t, I would have spent the extra $20 on Amazon to order the Health kit. I have tested with all of the major DNA companies directly, waiting for sales to save money on ordering. The advantage is I can compare directly with the same amount of SNPs with each company.

Whether it’s a mother finding her son, or a daughter finding her father, or brothers and sisters meeting for the first time, stories of adoptees using DNA testing to connect to their biological family are profoundly moving.
But DNA testing is also profoundly powerful because it can give adoptees —and their children and grandchildren — an opportunity to discover health risks they might not learn otherwise.
At-home DNA testing has surged in popularity in recent years, with well over 12 million kits sold at 23andMe. The boom in DNA testing comes at a time of other societal shifts in the world of U.S. adoptions. A New York State law went into effect in 2020, enabling adult adoptees access to their original birth certificate. Many other states have already made the change, and others will be expected to follow in the future.
The reasons behind a search for biological relatives are unique in every instance. On top of a search for information about biological origins, interest in the health information that can be gleaned from DNA also grows. More uses are available for DNA testing in the medical sector each year, ranging from the prescription of medications to the prediction of who is at higher risk of developing certain cancers.
Types of Information to Come from At-home DNA Tests
23andMe offers direct-to-consumer testing at three levels, which include an Ancestry + Traits service, and Health + Ancestry service, and a VIP service that includes Health + Ancestry with extra features that include accelerated processing times and one on one customer care walkthrough. All of these services can https://www.23andme.com/compare-dna-tests/help consumers who are adopted and have limited access to some or all of their history. Depending on what is desired, adopted individuals might choose from
The options all use the same type of testing–genotype analysis–and look at markers that give information on ethnic ancestry, DNA relatives, select traits influenced by genetics, and certain health-related* reports.
Whether (and When) to DNA Test?
Just like non-adopted individuals, people who are adopted have needs as unique as their DNA. There is no one test or one reason for testing that fits all. Even the right time to order a DNA test varies from one person to the next.
