DNA TESTING FOR CHINESE ADOPTEES

When you’re searching for Chinese birth family members, it’s critically important to do a SNP (also called autosomal) DNA test through 23andMe and upload it to GEDmatch. You can also do a STR (also called paternity/CODIS) DNA test uploaded to Chinese databases. If you wish to anonymize your information, you can create any name and birth date you wish and use a separate/special email.

SNP DNA Test [also called autosomal]

This tests the autosomal (i.e., 22 numbered pairs of) chromosomes as opposed to the sex chromosomes (i.e., X and Y). The test checks about 700,000 pairs of locations in an individual's autosomal DNA. Companies like 23andMe and AncestryDNA use SNP tests. SNP stands for single nucleotide polymorphisms, or SNPs (pronounced "snips").

IMPORTANT: No matter which SNP test you do, you should UPLOAD, FOR FREE, YOUR RESULTS TO GEDMATCH. As of October 2022, there are over 800 Chinese birth parents in GEDmatch.

23andMe

Most Chinese adoptees are in 23andMe, and you typically find more people of Chinese heritage in this database than any other SNP company. 23andMe is a saliva test.

AncestryDNA

If you can afford it, you can supplement your 23andMe test with AncestryDNA, another SNP test. Some searchers have found Chinese relatives here, and adoptive families not involved in China-related Facebook groups may have also tested with AncestryDNA. This is a saliva test.

GEDmatch

How-to Guide: Uploading 23andMe to Gedmatch

No matter which SNP test you do, be sure to upload your raw DNA data file to GEDmatch.

There are at least 800 birth families from China in GEDmatch thanks to the work of DNAConnect, Nanchang Project, Roots of Love, and others (see below). This is FREE and easy to do. GEDmatch accepts uploads from 23andMe, FamilyTree DNA, AncestryDNA, My Heritage, and most others.

You can also match your own 23andMe and AncestryDNA results within GEDmatch. You may receive different matches for your 23andMe and AncestryDNA test results.

DNAConnect.Org

Nanchang Project &
The Roots of Love

DNAConnect.Org has located hundreds of Chinese birthparents and uploaded their DNA to GEDmatch. As of October 2022, they have successfully matched 140 adoptees to their birth families.

Note: DNAConnect.Org will collect and process SNP DNA for any birth family that is located and also stay in contact with them over the next 10 years or longer until a match is made.  DNAConnect.Org charges to release birth parent contact information (being waived in a pilot project in 2022) – $50 if your donation is made before a match and $299 if made after a match. However, if you provide contact information for a birth family in China, any future match to you through DNAConnect.Org will also be free of fees to you.  

Both Nanchang Project and The Roots of Love are now adding birthparent DNA to GEDmatch through 23Mofang tests completed by birth parents in China. All matches are free of charge.

Other SNP DNA Sites

Chinese Companies

Upload your raw SNP DNA data to the two primary Chinese sites, 23mofang and WeGene. There has been at least one match for an adoptee through 23mofang, and both sites give you information about which provinces and cities have people genetically closest to you.

23Mofang

How-to Guide: Uploading DNA to 23mofang

Accepts uploads for a fee (approx $45 USD) from 23andMe, AncestryDNA. Database is kept in China. A little challenging to use if you can’t read Chinese. 

WeGene

Accepts uploads from 23andMe and AncestryDNA with payment through PayPal (199RMB or ~$30USD). Database is kept in China.

Tip: Use the English site to create your account and upload your DNA data, but then use the Chinese site, with Google Chrome to translate, to see relative matches and additional information not visible on the English site.

U.S. Companies

Also consider uploading your SNP data to the following databases. These are all free and increase your chances of matching more people.

FamilyTree DNA 

Accepts free uploads from 23andMe, AncestryDNA, MyHeritage. FamilyTree DNA is a swab test – good option for those who can’t generate enough saliva. 

My Heritage

Accepts free uploads from AncestryDNA, FamilyTreeDNA, 23andMe, Living DNA. MyHeritage is a swab test – good option for those who can’t generate enough saliva. 

Living DNA

Accepts free uploads from AncestryDNA, 23andMe, MyHeritage, FamilyTree DNA. 

IMPORTANT

DON'T FORGET!

Foggy Mountains
Please check your account(s) at least monthly for new matches!

If you get a message or see a match that shows an identical twin or sibling, please check first who the match is. You could have accidently uploaded your/your child’s DNA twice.

STR DNA Test [also called paternity/CODIS]

STR DNA tests look for unique repeating patterns in an individual’s DNA known as short-tandem repeats, STRs. STRs can be used to differentiate one person from another. Typically, an STR DNA test compares only 13 to 20 autosomal STR markers. With a STR test, you will only find a match to a close relative like a parent or identical twin.

 

There are four databases that only take STR test results, and not SNP like 23andMe. It's the most commonly-used DNA test in China right now.

Where to get a STR test:

LabCorp - USA, purchase the at-home single party test for $105. (New York residents can't order the at-home test, but will need to go to the local LabCorp office for the DNA test; cost is around $210.)

DNA Diagnostics Center (DDC), offered at a discount through DNAConnect - $80 if you use USPS, or $95 if you select FedEx. Contact Mary Hult at 513-645-8886 or mhult@dnacenter.com to order, and tell her that DNAConnect sent you to get the discount.

Consanguinitas - Netherlands, €149

PappaTest - Sweden, SEK 1,195

EasyDNA - based in UK, with worldwide offices, £99

SUBMIT YOUR TEST RESULTS TO THESE FOUR DATABASES 

Baby Come Home (Baobeihuijia)

How-to Guide: How to Search on Baby Come Home

Started by Chinese parents whose children were abducted or went missing (baobeihuijia.com), this group focuses on helping Chinese citizens find missing relatives. There are listings of Chinese birth parents looking for children, domestic Chinese adoptees looking for their birth parents, ads for lost adults, and international adopted children looking for birth parents. Open the website in Google Chrome to automatically translate the site into English. 

To register with Baby Come Home and submit your STR DNA report, join the Facebook group Baby Home. Your DNA is automatically compared with DNA from others in the database. Look in the files section of the Baby Home Facebook group for information on how to register.

Chinese National and Local Databases

If you're visiting China, you can leave a DNA sample at the Ministry of Public Security (police station). It's free, but the uploads aren't always reliable.

There are several ways to enter your STR DNA into the national police database in China.

You can have DNAConnect.Org submit your results for you. Also If you traveled to China in the past and left a DNA sample with the police, DNAConnect can verify that the sample was actually submitted (which hasn’t always happened, as a recent experiment showed 40% of police station samples were never uploaded). You can submit your results anonymously so that only DNAConnect will know your identity. If there’s a match to just to one birth parent, they will conduct a follow-up SNP test and upload the results to GEDmatch for verification. The fee for this service is $25. Email BrianStuy@Research-China.org.

DNAConnect has worked out a discounted price for an STR test with DNA Diagnostics Center (DDC) - $80 if you use USPS or $95 if you select FedEx. Contact Mary Hult at 513-645-8886 to order. Tell her DNAConnect sent you to get the discount.

DDC can also work with international orders - call Mary Hult at 513-645-8886 or email her at mhult@dnacenter.com, and she will provide a step-by-step process for adoptees living outside the U.S.

There are also local volunteer groups in China with their own databases, such as one in Jiangyin, Jiangsu and one for Zhejiang province. Check with the province search poster manager for your province to find out if they know of any in your area.
