Paternity Testing

DNA paternity testing is the most powerful, reliable method of proving the biological relationship between a man and a child. A child inherits one-half of his or her genetic pattern from the mother and one-half from the father.
We routinely provide results with a probability of 99.99% or greater for inclusion (The biological father) and probability of 0% (Not the biological father), which is a 100% exclusion.


Tested Parties:

  • Alleged Father
  • Mother (If available for testing)   
  • 1 or more Child(ren)

 

Other Related Testing

 

Avuncular DNA Test

Avuncular DNA test is performed in the absence of an alleged father determines the relationship between a child and the brother or sister of the alleged father.

Tested Parties:

  • Child
  • Mother (If available for testing)   
  • 1 or both Aunt or Uncle

 

Grand Parents Test

GrandparentageA grandparentage DNA test determines whether a couple could be the biological grandparents of a child. It is an indirect way to determine family relationships when an alleged father is not available for a paternity test. Grandparentage test results may be used as proof in Social Security benefit and other inheritance claims as well as in some immigration cases.

The child’s DNA profile is compared with the DNA profiles of the alleged father’s biological parents. Since a child inherits half of his/her DNA from the mother (maternal side) and half from the father (paternal side), the paternal half should match DNA passed down from the alleged grandparents. The mother’s participation is encouraged to expedite analysis; motherless grandparentage tests take longer to complete because of the extended analysis required.

Tested Parties:

  • Child
  • Mother (If available for testing)    
  • 1 or both Grand Parents

 

Siblingship Test

A siblingship test determines if two or more individuals have common parents. Full siblings share both parents while half-siblings share one parent.

DNA samples from both alleged siblings are necessary. Testing of the parents also increases the accuracy of the test. Unlike paternity testing which provides very conclusive results, the results of siblingship testing are not always conclusive, and are dependent on the genetics of the individuals being tested.

Generally, a siblingship test will not provide a conclusive answer; however, it will likely provide an indication of whether you are more likely to be or not to be the true biological sibling of the other tested individual. The fee for this test is based on the number of individuals tested.

Tested Parties:

  • Child
  • Mother (If available for testing)                  
  • 1 or both brother or Sister

Prenatal Paternity Test

Prenatal paternity test is available to determine paternity before a baby is born. The specimen collected is compared with the DNA profile of the alleged father and mother; because the unborn Childs' DNA is determined at conception, the prenatal test yields the same conclusive results as the standard paternity test.

Chorionic Villi Sampling

This is version of paternity testing while pregnant that is carried out from the 10th to the 13th week. This method collects a sample from the placenta which is the membrane that surrounds the developing fetus and here the doctor uses a catheter that is guided through the vagina. If the doctor determines that the position of the fetus warrants it, a long hollow needle can be inserted through the abdomen.

Amniocentesis

Paternity testing before birth can also be carried out by amniocentesis. As is often the case where court ordered paternity testing is necessary, this procedure is carried out in the 16th through the 24th week. This is also an invasive procedure unlike the more familiar versions of paternity testing, and the results here can also be used to help in the resolution of child support cases. Here the samples are collected in the form of loose fetal cells that float in the amniotic fluid that surrounds the developing baby. Once again a long needle is used to go through the abdomen here.
