DNA Testing

IMPORTANT ANNOUNCMENT: MyTaproot will be closing May 31, 2022. Please ignore any instructions about doing a CODIS DNA test and uploading to MyTaproot until we have time to make the corrections to our website. Focus for now on autosomal testing through companies like 23andMe with results uploaded to Gedmatch. Thank you.


When you’re searching for Chinese birth family members, it’s important to do two different DNA tests – an autosomal DNA test through 23andMe and uploaded to GEDmatch and a CODIS/STR DNA test through MyTaproot. If you wish to anonymize your information, you can create any name and birth date you wish and use a separate/special email.

Autosomal DNA Test

This is a test of 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 autosomal tests.

IMPORTANT: No matter which autosomal test you do, you should UPLOAD, FOR FREE, YOUR RESULTS TO GEDMATCH. As of March 2022, there are nearly 700 Chinese birth parents in GEDmatch.


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


If you can afford it, you can supplement your 23andMe test with AncestryDNA, another autosomal 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.


How-to Guide: Uploading 23andMe to Gedmatch

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

There are at least 700 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.


Nanchang Project & Chongqing Roots of Love

DNAConnect has located hundreds of Chinese birthparents and uploaded their DNA to GEDmatch. As of March 2022, they have successfully matched 115 adoptees to their birth families.

Note: DNAConnect.Org will collect and process autosomal 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 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 will also be free of fees to you.  

Both Nanchang Project and Chongqing 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 DNA Sites

Chinese Companies

Upload your raw autosomal DNA 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.


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. 


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.

US Companies

Also consider uploading your autosomal 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.

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.


This is the FBI’s Combined DNA Index System (CODIS), a software platform that blends forensic science and computer technology. 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, a CODIS/STR DNA test compares only 13 to 20 autosomal STR markers.

You don’t see CODIS/STR tests advertised since this type of test is primarily used by the FBI and local law enforcement organizations to help solve crimes. A paternity test to determine the father of a child is a CODIS/STR DNA test. It is however the most commonly-used DNA test in China right now.


Baby Come Home (Baobeihuijia)

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

This is a Chinese website started by Chinese parents whose children were abducted or went missing ( It was created to help Chinese citizens find missing relatives. It has 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. If you open this Chinese website in Google Chrome, you can automatically translate the site into English. 

There are two options to register with Baby Come Home.

1.  The first option to register with Baby Come Home is to sign up with MyTaproot

  • Read the information on the MyTaproot page carefully. After you finished the steps, you can order a DNA test for $70 via their partner LabCorp (MyTaproot will tell you how to do this). It is also possible to do this if you are located in Europe,  but there is an additional shipping charge of $100. It may be cheaper to get an STR or CODIS test done in your own country; check with MyTaproot for compatibility.

  • MyTaproot will register your child with Baby Come Home (Baobeihuijia) in China and your DNA results will be compared. You will get a registration number. It might take several months. The DNA results will also be compared by MyTaproot with Haiwaixunzi, the Chinese database side of MyTaproot.

Help for Family Reunion (HFFR)

Chinese National DNA Database

If you are searching within China, you could also leave a DNA sample in the national database at the Ministry of Public Security (i.e., police station). It is free. Since this is also a CODIS/STR DNA database you will only find a match to a close relative like a parent or identical twin.
