Other DNA Testing Services

Worldwide Genetics offers a wide range of DNA testing services, including family relationship testing and DNA banking and profiling. Please click on the links below for specific information about each test.

Family Relationship Testing
Family relationship tests use DNA to determine biological relationships such as grandparentage, siblingship, and others. These tests are usually performed as an alternative to paternity testing when the alleged father is unavailable. Maternity testing and twin zygosity testing are also available.

If you are unsure about which test is applicable to your situation, please do not hesitate to contact us via our online form or call 1-800-DNA-8360. We will evaluate the information you provide about the family members who are available for testing and help you determine which test best fits your situation.

Grandparentage Testing
We can test an alleged father’s biological parents (a child’s alleged grandparents) with a child to determine if the child is biologically related to the family.

Siblingship Testing
A siblingship test can help two individuals determine if they are full or half siblings. Usually, this test is used to indirectly determine paternity (i.e., to determine if the two children share a father).

Reconstruction Testing
Reconstruction testing compares the DNA profiles of an alleged father’s close relatives with the profile of a child. This form of testing is usually helpful when the alleged father cannot be tested and one or both of his parents are also unavailable for testing.

Maternity Testing
Maternity testing is commonly used to confirm the biological relationship between a mother and child who have been separated by circumstances such as adoption. Often, adoption records are sealed and only a DNA maternity test can provide the definitive answer the reunited mother and child are seeking.

Twin Zygosity Testing
Twin zygosity tests determine if twins are fraternal or identical. Results of a twin zygosity test not only provide information to satisfy curiosity; they also serve as an important piece of the twins’ medical history that may aid in the diagnosis, prevention, and treatment of disease later in life.

DNA Banking and Profiling
Our DNA banking and profiling services help you plan for future unexpected events.

DNA Banking allows you to have a DNA sample stored for 15 years at our secure facility, in case it is ever needed for a future DNA test, such as a paternity test, in the event of illegitimate claims on your estate.

DNA Profiling is a DNA test that determines your DNA profile and serves as permanent identification. A DNA profile can be used in future DNA tests and in the identification of missing persons.
