Understanding the differences

Private vs. Legal DNA Testing

Private DNA testing is a convenient and affordable way to establish biological relationships, such as paternity, sibling, or grandparent connections, in a personal and private setting.

With private DNA testing, you can collect your DNA samples using a simple at-home cheek swab kit and send them directly to the laboratory for analysis.

Private DNA testing offers the same level of precision as legal DNA testing, but the process does not require strict chain of custody procedures or sample collection by an unbiased third party. This makes it a great option for those who want to maintain privacy and control over the testing process.

It’s important to keep in mind that the results of a private DNA test are not legally admissible in court. If you need DNA testing for legal purposes, you’ll need to choose a legal DNA testing option.

Legal DNA testing is a highly regulated procedure that is used to establish paternity or other biological relationships for legal purposes.

Legal DNA test results are commonly used in child custody and support cases, inheritance disputes, immigration cases, and other legal proceedings where the biological relationship between individuals needs to be established.

Legal DNA tests require the DNA samples to be collected by an unbiased third party following a strict chain of custody protocol. You can arrange for sample collection and witnessing services yourself, or we can assist you in setting up appointments at one of our locations.

Genetrack offers legal DNA testing services that are court-admissible throughout the US and Canada.

Whether you need to establish paternity, sibling relationships, or other biological connections, Genetrack offers both private DNA testing and legal DNA testing services to meet your specific needs.

Child custody and support cases: Legal DNA testing is often used to establish paternity and determine child support obligations in cases where the biological relationship between the father and child is in question.

Inheritance disputes: In cases where the biological relationship between the deceased and their potential heirs is disputed, legal DNA testing can be used to establish biological relationships and determine inheritance rights.

Immigration cases: Legal DNA testing may be required to establish biological relationships between Canadian citizens or permanent residents and their foreign-born family members who are seeking to immigrate to Canada.

Adoption: Legal DNA testing may be used in adoption cases to establish the biological relationship between the child and their biological parents.

About Immigration DNA Testing

Frequently Asked Questions

Immigration DNA testing refers to the process of conducting a paternity, maternity, or kinship test upon the request of governing bodies such as the U.S. Embassy, Department of Homeland Security, or United States Citizenship and Immigration Services (USCIS) to confirm biological relationships between family members in immigration cases.

When applying for a U.S. passport, a U.S. Consular Report of Birth Abroad (CRBA), or a U.S. immigrant visa, a consular officer or U.S. Citizenship and Immigration Services (USCIS) may recommend Deoxyribonucleic Acid (DNA) testing between family members when applicants have been unable to establish to the consular officer’s or USCIS official’s satisfaction that a required biological parent-child relationship exists. DNA testing is the most accurate and widely available technology to prove a biological relationship. DNA testing is entirely voluntary and, as such, all costs of testing and related expenses are borne by the applicant and paid to the laboratory in advance.

When applying for a visa and citizenship for your family, you may need to legally verify their familial relationship through a DNA test. The results of this test will be submitted to immigration authorities. It is crucial to choose an accredited laboratory, like Genetrack, which has been accredited by the American Association of Blood Banks (AABB). All aspects of the immigration testing process, including scheduling the appointment, should be handled directly by the AABB-accredited laboratory, rather than a third-party.

An immigration DNA test is a test conducted by an AABB-accredited laboratory that is recognized and accepted by the United States Citizenship and Immigration Services (USCIS) as proof of a biological relationship. You may need immigration DNA testing if you are applying for a US passport, a US Consular Report of Birth Abroad (CRBA), or a US immigrant visa, and there is insufficient evidence to prove the biological relationship.

The cost of immigration DNA testing varies depending on the number of people being tested and where everyone is located. Please contact us directly for a personalized quote  by filling out our online quote form or contacting us by phone or email. Our team will respond within 24 hours with a personalized quote.

The DNA letter is a letter issued by the United States Citizenship and Immigration Services (USCIS) suggesting DNA testing to support a claim of a biological family relationship for immigration and citizenship applications. Our laboratory requires this letter to initiate the immigration DNA testing process, as it contains specific procedures and requirements for the test that depend on the locations of each family member.

Once you decide to go ahead with immigration DNA testing, our laboratory will schedule an appointment for all parties to go our immigration approved collection site for sample collection. At the appointment, a painless mouth swab is collected by rubbing a swab gently inside the mouth for 15 seconds. Once the laboratory receives your samples, testing is completed in just 1 to 2 business days.

DNA samples are collected by an impartial third-party specimen collector, who will use a sterile buccal swab to gently scrape the inside of the cheek to obtain a DNA sample. The collection process is quick, painless, and safe for individuals of all ages, including infants, children, and adults.

No, the family members involved in the immigration DNA test do not need to be present at the same location. Genetrack has a global network of specimen collectors to collect DNA samples from all over the world. We can coordinate the sample collection process at multiple locations, both within the United States and internationally, to accommodate the needs of your family.

If your family member is located within the United States, we will contact your family member to set up a sample collection appointment at a nearby specimen collection location.

If your family member is located outside of the United States, we will send a tamper-proof DNA sample kit with detailed instructions directly to the migration office or consular mission closest to your family member. The migration office or consular mission will contact your family member to schedule an appointment for the collection process, and a migration officer or staff member will be present at the time of collection to ensure the integrity of the sampling procedure.

Yes, we take the privacy and confidentiality of our clients seriously. All personal information and test results are securely stored and only shared with authorized parties involved in the immigration process.

Our immigration DNA testing results are available within 1 to 3 business days after we receive all the DNA samples. Once the results are ready, we will provide you with an official copy of the results and send a second official copy directly to the United States Citizenship and Immigration Services (USCIS).
