Maternity A maternity DNA test establishes whether the tested woman is the biological mother of the child in question. DNA maternity testing works much like a paternity test, except this analysis compares a child’s DNA profile with the mother’s instead of the father’s. Even without testing the father, DDC’s maternity testing services can conclusively determine if the child’s DNA matches that of the mother.
Grandparent When a possible father is not available for paternity testing, one or both of his parents can participate instead. DDC’s Grandparent DNA Test can confirm a biological relationship between a child and their grandparent(s), providing the answers and peace of mind that you need.

Sibling DNA Test When a possible father is not able to provide a DNA sample, you can confirm paternity through a sibling DNA test instead. Sibling DNA testing can also confirm potential relationships found through ancestry testing. City Biometric Labs Sibling DNA Test can verify a biological relationship between a child and their full-sibling or half-sibling, providing the answers and peace of mind that you need.

Twin DNA Test Typically twins are classified as identical or fraternal by a doctor at birth, based on physical observations and placental analysis, though these methods aren’t always accurate. A twin DNA test (also known as a twin zygosity test) can definitively confirm whether twins are identical or fraternal. City Biometric Labs' Twin DNA Test compares the genetic markers of each twin to determine whether or not their genetic profiles match, and can be utilized by twins of all ages.
What is a DNA family reconstruction test used for?
City Biometric Labs can provide reliable DNA results for complex family cases. Do you have a family puzzle and you’re trying to put all the pieces together? When close potential relatives are unavailable for testing, there may be other relatives who can help to fill in the gaps and determine a child’s genetic relationship to the family. DNA Family Reconstruction Testing is a series of tests that can help you get accurate answers fast. The report is posted to your secure online account 5 business days after all samples have been received at the lab. We specialize in complex cases. Contact our experts today for a free consultation.
Aunt/Uncle Avuncular DNA Testing
How can you determine paternity without testing the father? With the cooperation of an aunt or uncle, we can do an avuncular DNA test to determine if there’s a match between the child and the man believed to be the father. Whether you need to confirm a paternal relationship for legal reasons, obtain medical information, or simply want the truth about a biological relationship, our avuncular test will provide you with accurate, reliable results and the answers you need to move forward.
Y-Chromosome DNA Tests
A Y-chromosome DNA test, also known as Y-DNA testing, is a powerful tool for tracing paternal relationships. By analyzing the Y-chromosome, which is passed down from father to son, we can help you uncover relationships along your direct male line.
Whether you want to confirm the truth about a biological relationship along your direct male line,
determine paternity between a male child and a possible father, or gather information about your medical history, our paternal lineage DNA test offers the accuracy and reliability you need.
When do you need a mitochondrial DNA analysis?
Our mtDNA test—also known as a maternal lineage test—uses mitochondrial analysis to confirm your relationship to relatives and possible ancestors through the maternal/female line. It can also provide additional information for situations where maternity is in question, but the mother is unavailable for a maternity test. Although maternity itself can’t be determined, we can determine the child’s relationship to a possible maternal relative. The report is posted to your secure online account 9 business days after all samples have been received at the lab. Contact our experts today for a free consultation.
Native American DNA Test
Do you need proof of a biological relationship to apply for tribal membership? Native Americans across the United States utilize our Native American DNA Test to establish biological relationships and provide supporting evidence often required for tribal membership/enrollment. Contact our experts today for a free consultation. DDC has a dedicated team and special phone number to help assist with tribal membership DNA test services.
NOTE: This is not an ancestry test to determine if you have Native American “genes” or that provides “ethnic percentages.” This is a service that provides proof of biological relationships between an applicant and existing tribe member for the purposes of tribal enrollment/membership.
