Family Relationship DNA Testing
Premier Screenings has a wide range of family relationship DNA tests available. See all DNA testing available below in alphabetical order. We understand every situation is unique – contact us and a specialized DNA testing staff member will answer your questions and provide a customized price quote.
Adoption DNA Test
Another important use of DNA testing is to reunite biological family members who have been separated through adoption. DNA testing is the most effective way to reunite families–parents, grandparents, and siblings.
As with our other DNA tests, Premier will collect the necessary samples and submit them to our laboratory, where they will be analyzed and verified quickly. We offer this test for adoption cases that include:
- Domestic Adoption (which includes any cases of contested adoption or surrogate reproduction)
- International Adoption
Ancestry DNA Test
Premier uses the world’s leading DNA testing laboratory to conduct all of our Ancestry DNA tests. Our Ancestry DNA tests are affordable and through our accredited laboratory, we offer the highest quality and accuracy.
A DNA Origins test determines an individual’s bio-geographic ancestry. Whether you’re interested in researching your family history, or just simply want to learn more about yourself, this test can provide you with a better understanding of your genetic ancestry and provide a window into further research about your possible ancestors. DNA Origins provides ancestral estimates for four populations: European, Indigenous American, Sub-Saharan African, and East Asian. It is important to remember that these “populations” really refer to a group of people with shared ancestry and that there is natural migration between these groups over time.
The paternal lineage test is based on the fact that the Y chromosome is passed down from father to son relatively unchanged through several generations. Only males have the Y chromosome, so this test is only available to males, however if a female would like to know her paternal lineage, she could have a brother or other relative from the paternal line take the test.
The maternal lineage test is based on human DNA passed down from mother to child relatively unchanged through several generations. Our mtDNA contains markers that can be traced to early ancestors and where they settled thousands of years ago.
The dual linage DNA test is based on human DNA passed down from both the father and mother (Maternal & Paternal). This test is available to males only.
DNA Full Spectrum
A DNA Full Spectrum is an analysis of your personal history. After first determining the origins of your ancestors, DNA Full Spectrum compares your DNA to populations living today to determine with whom your DNA has the most in common.
Avuncular DNA Test (Aunt/Uncle)
An avuncular DNA test (aunt/uncle) is used to determine paternity or maternity by testing an alleged parent’s sibling–brother or sister. The test determines a statistical probability–an avuncular index, where less than 1.00 means no relationship exists, but where greater than 1.00, it is more likely that a biological relationship exists between aunt/uncle and niece/nephew.
Grandparents DNA Test
A grandparents DNA test is used to determine a child’s true biological parent when the alleged father/mother is unavailable for testing. To accurately determine a child’s family lineage, Premier tests both paternal and maternal grandparents, and recommends that both grandfathers and grandmothers are present to obtain the most reliable results. However, tests can still be conducted with only one grandparent present.
A Maternity Test determines whether a woman could be the biological mother of a child. Like a DNA paternity test, it compares a child’s DNA pattern with that of the alleged mother to determine how likely it is that the child has inherited the DNA from the alleged mother.
Maternity test results may be used in the following circumstances:
- To confirm that an adoptee has been reunited with his/her birth mother
- To prove biological relationships in an immigration case.
- To confirm that an embryo conceived through in vitro fertilization was implanted into the correct mother
- To resolve situations in which mothers or hospital staff suspect that a baby mix-up has occurred in the nursery
In a maternity test, the child, alleged mother, and biological father are tested. The father’s participation in the maternity test helps to exclude half of the child’s DNA, leaving the rest for comparison with the alleged mother. If the father is not available, we can perform a fatherless test, which involves additional analysis, without additional charge.
Sibling DNA Test
A sibling DNA test concludes whether tested siblings are full or half siblings. For more accurate test results, it is best if a parent is also available for collection. However, tests can still be completed and will still be statistically accurate if a parent it not available.
Premier performs two types of sibling DNA tests:
Half Siblingship — the test performed when two alleged siblings do not share the same biological mother, but want to know if they share the same biological father.
Full Siblingship — the test performed when two siblings know they have the same biological mother, but want to know if they also share the same biological father.
Twin zygosity tests determine whether twins are identical or fraternal: Identical twins come from a single fertilized egg that split into two genetically identical parts; Fraternal twins, however, come from two separate eggs which are fertilized and implanted in the uterus.
Though many delivering physicians try to determine whether twins are identical or fraternal at the time of birth, it is not always accurate. The best way to accurately determine this, especially if the twins are the same sex, is through a simple DNA test.
This type of DNA testing—a person’s genetic fingerprint—is used for personal security, such as in the case of identifying a missing child or for a future inheritance claims. We take an individual’s DNA sample and determine the specific, genetic profile, a combination of 16 markers, which serves as his/her genetic ID.
A much more complicated test, genetic reconstruction, is performed when an alleged father is unavailable and grandparentage testing has been eliminated as a possible test option. Genetic reconstruction then compares a child’s DNA profile to several known relatives of the alleged father to determine if there is a biological connection.
Several individuals are needed for a genetic reconstruction test:
- If the child’s mother is available: she, the child, and at least two close
relatives of the alleged father.
- If the child’s mother is unavailable: the child, and at least three close relatives of the alleged father.
A mitochondrial DNA maternal lineage test compares the DNA of one individual with a possible relative’s DNA to determine if they are related through a maternal line. Mitochondrial DNA is passed from a mother to her children (both sons and daughters inherit the mtDNA, but only daughters can pass it to their children).
In a mtDNA test, the tested individuals’ mtDNA is sequenced and then compared to determine whether the individuals share a maternal line. In order for an mtDNA test to be performed, two or more individuals who would like to know if they are biologically related through a maternal line are necessary. (Note: Tested individuals may be male or female.)
Y-STR DNA Test
A Y-STR paternal lineage test determines whether two or more males are biologically related through their paternal line, and directly compares a male’s DNA with another male’s DNA to confirm whether or not they are related through a paternal line. This test, however, only determines whether males are paternally related. It cannot determine the how they are related (i.e. father/son, uncle/nephew, grandfather/grandson).
In order for a Y-STR test to be completed, two or more males who would like to know whether they are biologically related through a paternal line, need to participate. (Note: All Y-STR participants must be male). Because a son inherits his Y-chromosome directly from his father, Y-chromosomes can be profiled and compared to determine whether individuals are biologically related through a paternal line.
