Paternity Test
A DNA Paternity Test is the most commonly known type of DNA test which determines biological paternity. In plain English – this test determines who the daddy really is…or isn’t.
Specimen collections for this type of test require a non-invasive cheek swab collection from the child and the alleged father(s). A specimen collection from the mother is preferred, although not required for this test.
Testing and results can be delivered for personal information only or for legal purposes such as child support, child custody, estate claims or birth certificate changes. Our staff is happy to discuss the particulars of your case and what kind of test may be the most appropriate.GRANDPARENTAGE TESTING
A DNA Grandparentage Test is performed to determine paternity for a child when the alleged father is not available or unwilling to be tested. Probability of paternity can be established through the testing of the paternal grandparents.
Specimen collections for this type of test require a non-invasive cheek swab collection from the child, the mother and at least one paternal grandparent (both grandparents are preferred).
Because of the rare instances for this type of DNA test, only a Legal Test is performed.SIBLINGSHIP TESTING
There are two types of DNA Siblingship tests:full siblingship and half siblingship. A siblingship test provides the likelihood of relationship between two possible siblings, specifically when no other relatives are available for testing. Like an avuncular test, this test should only be used as a last resort when attempting to determine paternity.
A full siblingship test is performed when both parties (alleged siblings) know they share the same mother, but want to determine if they share the same father.
A half siblingship test is performed when both parties (alleged siblings) know that they have different mothers but want to know if they share the same father.
Specimen collections for this type of test require a non-invasive cheek swab collection from both parties. A specimen from the mother(s) in either type of test is encourage but not required.
Because of the rare instances for this type of DNA test, only a Legal Test is performed.Avuncular Test
An avuncular DNA test, also known as an aunt-uncle DNA test, is a genetic test used to determine the likelihood of a biological relationship between a child and a potential aunt or uncle. This test is often used when the alleged father is unavailable for testing, and a sibling of the alleged father (aunt or uncle of the child) is willing to provide a DNA sample for comparison. The test compares the DNA of the child with that of the potential aunt or uncle to see if there are enough genetic similarities to support the conclusion that they are related. It relies on the fact that aunts and uncles share genetic material with their nieces and nephews because they are siblings of one of the child's parents.Twin Zygosity Test
A twin zygosity DNA test is a genetic test used to determine whether twins are identical (monozygotic) or fraternal (dizygotic). Identical twins occur when a single fertilized egg (zygote) splits into two separate embryos. These twins share nearly identical genetic material because they originate from the same egg and sperm.
Fraternal twins, on the other hand, occur when two separate eggs are fertilized by two different sperm. They are genetically similar to any other siblings, sharing approximately 50% of their DNA. The twin zygosity DNA test analyzes the genetic material of the twins to determine whether they are identical or fraternal. This is typically done by comparing specific genetic markers or variations in their DNA. If the genetic profiles of the twins are nearly identical, they are considered identical twins. If their genetic profiles are more similar to those of regular siblings, they are considered fraternal twins.Maternity Test
A maternity test is a genetic test used to confirm or establish the biological relationship between a mother and a child. It's typically done when there is a need to verify or confirm the identity of the biological mother, such as in cases of adoption, surrogacy, or disputed maternity.
Maternity testing usually involves collecting DNA samples from the mother and child, often through a simple cheek swab or blood sample. The DNA samples are then analyzed to compare specific genetic markers or variations. Since a child inherits half of their DNA from their mother, a maternity test examines these genetic similarities to determine whether the tested woman is the biological mother of the child.
