DNA Test - Philadelphia, Pennsylvania

Philadelphia PA DNA Testing Locations

Types of DNA Tests at our Philadelphia, Pennsylvania clinics:

Paternity Testing can conclusively establish whether or not a man is the biological father of a child.

Relationship Testing for other close family relationships can be performed at our testing centers. Our DNA testing services can confirm or deny biological relationships between grandparents, grandchildren, siblings, half-siblings, aunts, uncles, nieces and nephews:

Grandparent DNA Test (if the father is not available for testing)
Sibling DNA Test (possible brothers, sisters, or half-siblings)
Avuncular DNA Test (aunt/uncle and niece/nephew)

Specimens we can test for DNA

The easiest and most reliable way to obtain a DNA sample for paternity testing is to swab the inner cheeks of the alleged father and child or children. These skin cells are known as buccal cells, and they rub off easily onto cotton swabs and remain in place for analysis by our laboratory.

Other specimen samples, such as hair follicles, fingernails, and garments that might contain someone's DNA, can also be tested. An Alternative Specimen DNA Test is done by ordering one of our testing kits online and shipping the specimens back to us.

Legal DNA Tests vs. "Peace of Mind" At-Home Tests

A Legal Paternity Test is a court admissible lab testing service performed at an AABB accredited laboratory. Accurate results for DNA paternity testing with 99.99% confidence or greater take about a week.

When deciding which type of DNA test is right for you, consider first what you might do with the results. A legal paternity DNA test will hold up in court for such matters as child support or to change the name on a birth certificate. This test must be performed using strict chain of custody procedures. Our Philadelphia DNA testing technicians are trained to follow these guidelines so that the results will be legally admissible.

Philadelphia, Pennsylvania - DNA Testing

Establishing paternity in Philadelphia, Pennsylvania

Paternity can be established through marriage or by signing the Acknowledgment of Paternity. This form is a free and voluntary way to establish paternity and does not require approval by the court, but do not sign this form if you are unsure about being the father of the child.

Another possibility is a court establishing the legal father of the child. That usually happens by DNA test, which identifies whether there is a biological relationship between the two people by comparing their DNA. DNA is collected painlessly by cheek swab test.

Proving paternity in Philadelphia, PA

There are many ways an individual can prove paternity in Philadelphia, PA. One of them is a DNA test. An individual can do genetic testing privately; however, the results will not determine the legal responsibilities of the child since the DNA testing was not supervised by a professional, certified lab.

The parties can agree to accept the tests without a hearing, but if they do this and it shows that the man is not the father, then any petition for support of custody rights will be dismissed.

If the mother wants child support or to determine her custodial rights and the father's right to see the children, then the court order establishing paternity will be necessary. The court will also be necessary if the father wants to spend time with the child but the mother denies he is the father. Also, if a child seeks benefits only available through the father, such as Veteran's benefits, Social Security benefits, or inheritance, the court may need to decide.

Suppose the father disagrees with the Acknowledgement or Court Order Establishing Paternity. In that case, he may file a complaint about Genetic Tests, a Motion to Set Aside a Prior Adjudication of Paternity, or an Appeal to the Superior Court of Pennsylvania.
