Currently, the number of foreigners living and working in Vietnam is quite large. It is no longer rare for an expat to marry and have children in Vietnam. For Vietnamese citizens, getting a birth certificate when a child is born is relatively simple and does not involve many procedures. However, for foreigners, how do you obtain a birth certificate or apply for citizenship for your child? DNA testing services for foreigners serve as an effective solution in this situation.
1. What is DNA testing?
DNA testing is a method that uses cells from our body to determine biological relationships. By analyzing the DNA of two individuals (with a suspected biological relationship), their genetic information can be determined. Because each person’s genetic information is inherited half from the father and half from the mother, DNA testing allows us to verify biological relationships with the highest accuracy available today.

2. Is DNA testing accurate?
DNA testing to determine biological relationships is the most accurate method available today. If the DNA samples of the mother, the child, and the alleged father match in every gene, the accuracy of a biological relationship is 99.9999% (with 16 genetic loci) and reaches up to 99.99999998% (with 26 genetic loci). If the DNA samples of the child and the alleged father do not match in two or more genes. Then this man is not the biological father of the child with 100% certainty.

3. Are foreigners allowed to get DNA testing while in Vietnam?
Foreigners are completely allowed to take DNA tests in Vietnam. They can choose either an informational (voluntary) DNA test to check biological relationships such as father-child, siblings… or a legal DNA test to be used in administrative procedures such as obtaining a birth certificate, applying for a visa, immigration, or sponsorship. When undergoing the test, clients need to provide valid identification documents (usually a passport). For legal cases, sample collection must be performed directly at the testing facility, with full identity verification (taking photographs, signing) to ensure the results are legally valid before competent authorities or consulates.
3.1. Informational DNA testing for kinship verification
Foreigners can entirely and legally undergo informational DNA testing in Vietnam to confirm biological relationships such as father-child or among family members. This is a common form of DNA testing for foreigners, chosen by many international clients. To verify kinship, we can utilize DNA testing to analyze the genetic profiles of the parents or relatives. The testing center will compare these genetic profiles to conclude whether the two parties are biologically related.
Informational DNA testing is performed entirely based on the client’s voluntary consent, requiring no complex legal procedures. All personal information and test results are strictly confidential. The clinic provides an at-home sample collection service, assisting foreign clients so they do not need to travel. Results can be delivered flexibly via email, WhatsApp, or other online platforms.
However, please note that informational DNA testing is for personal reference and confirmation only, carrying no legal validity. It cannot be used in cases involving obtaining a birth certificate for a child, immigration, or naturalization.
The turnaround time for informational DNA test results is usually quite fast, ranging from 24 hours to 3 working days. Informational DNA testing is a quick solution that helps foreigners verify biological relationships in Vietnam.
3.2. Informational prenatal DNA testing
In cases where the baby is not yet born but the father still wants to check the child’s biological relationship, a prenatal DNA test can be performed. This is an informational DNA test that helps verify the father-child relationship even while the baby is still in the mother’s womb. Fetal DNA present in the mother’s blood will be analyzed and compared with the father’s DNA to confirm kinship.
Non-invasive prenatal DNA testing is a highly accurate method of DNA determination, absolutely safe for both mother and baby. The fetal DNA will be extracted from a small amount of the mother’s blood, then analyzed and compared with the father’s DNA to reach a conclusion.
Medic Sai Gon Clinic provides an at-home sample collection service, helping expectant mothers save time and minimize travel. DNA test results for foreigners are delivered quickly and with absolute confidentiality, ensuring privacy and peace of mind for clients throughout the entire process.

3.3. Legal DNA testing for birth registration and naturalization purposes
Legal DNA testing is commonly used in the following cases:
- Foreigners who have not registered their marriage in Vietnam but wish to issue a birth certificate for their child using the father’s surname must perform a legal DNA test.
- When a child is born and the birth certificate carries the mother’s surname, but there is a desire to change it to the father’s surname for future paperwork convenience. A legal DNA test can be conducted to facilitate the change from the mother’s surname to the father’s.
- When performing administrative procedures involving foreign elements such as immigration, naturalization, visa applications, sponsorship, studying abroad, or inheritance of assets.
Advantages for foreigners performing legal DNA testing at Medic Sai Gon:
- Legal DNA testing not only ensures high accuracy but also comes with a complete legal dossier for use in administrative procedures both domestically and abroad.
- DNA test results for foreigners will be supported with English translation (or other languages upon request), suitable for submission to consulates, embassies, or international immigration authorities.
- DNA results are certified by the Ministry of Foreign Affairs and undergo consular legalization, ensuring the document’s validity abroad.
