Types of Testing



Paternity Testing

Legal DNA Paternity Test


DNA paternity testing determines the biological father of a child. We all inherit our DNA from our biological parents — half from our mother and half from our father. A DNA paternity test compares a child’s DNA pattern with that of the assumed father to determine if there is a match. When performed in an experienced, accredited laboratory, it’s the most definitive proof of a biological relationship — 100% accuracy guaranteed.

If you need paternity test results that can be used as a legal document, then a Legal DNA Test must be performed. Some common reasons for a Legal DNA Test include: 

  • Child Support
  • Child Custody
  • Immigration
  • Birth Certificate
  • Tax Forms
  • Will / Estate
  • Court Order
  • Adoption
  • Legal reasons

It’s painless, fast, and guaranteed accurate.

Paternity questions during pregnancy can be stressful. Fortunately, there’s a solution that can give you peace of mind before your baby’s born—and it’s completely safe.

 Non-Invasive Prenatal Paternity (NIPP) Test gives you accurate paternity answers without any risk to the baby or to you.

  • Testing as early as 8 weeks’ gestation
  • Results online in as few as 3 business days
  • Choose results: legal or peace-of-mind
  • Convenient appointments to suit your schedule
  • Optional gender determination



Maternity DNA testing determines the biological mother of a child. It works like a DNA paternity test, except this analysis compares a child’s DNA profile with his/her mother’s. Children inherit half their DNA from their father, and half from their mother. Even if the father is not tested, DDC can prove conclusively whether or not the child’s DNA matches the mother.

Maternity DNA testing is often requested in the following situations:

  • Resolving controversy that sometimes occurs in hospital nurseries
  • Providing life-long peace of mind after returning home from hospital
  • Proving an adoptee’s relationship with his/her biological birth mother
  • Proving a maternal relationship for immigration
  • Confirming accuracy for in-vitro fertilization


If you are trying to confirm if a person is your grandparent or establish paternity, but the father is not available for testing, a Grandparent DNA Test might be right for you.

Grandparent DNA Test results can be used for the same reason as a paternity test:

  • Social Security benefits
  • Inheritance claims
  • Immigration cases


When two people are trying to figure out if they share the same father, and the father is not available to provide a DNA sample, You can perform a Sibling DNA Test. This test determines whether two individuals share one or both parents.

If your goal is to establish paternity, and the father is not available for testing, we first recommend a Grandparent DNA Test. If the father’s parents aren’t available, the Sibling DNA Test is an indirect way to determine family relationships, including paternity.

There are many potential uses for the Sibling DNA Test.

  • Immigration visa
  • Social Security benefits
  • Personal knowledge


A twins test (also called “twin zygosity”), is a DNA analysis that definitively shows whether twins are identical or fraternal.

During OB-GYN visits, the physician might be able to tell whether twins are identical or fraternal through ultrasound examination of the placenta. There are cases, however, where twins find out much later that a DNA test shows the opposite of what the ultrasound examination determined! Scientists recommend DNA testing to determine zygosity—the degree of similarity. Medical records regarding zygosity may have been lost, or doubt may have arisen because of the twins’ physical characteristics as they age.


 Is it really possible to get a baby’s DNA from the mother’s blood sample? 

Yes! The fetal DNA combines with the mother’s DNA by passing through the placenta into the mother’s bloodstream.
