DNA Test - West Chester, Pennsylvania

West Chester PA DNA Testing Locations

Types of DNA Tests at our West Chester, 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 West Chester DNA testing technicians are trained to follow these guidelines so that the results will be legally admissible.

Establishing Paternity in West Chester, PA

Under Pennsylvania law, when the mother of a child is not married to the biological father, only the mother will possess parental rights until paternity is properly established. The paternity establishment process must be used in situations of children born outside of legal marriage to effectively identify the biological father and grant him paternal rights and responsibilities.

To establish paternity in the state of Pennsylvania, two West Chester parents can sign and submit an Acknowledgment of Paternity Form to the Department of Human Services. Bear in mind that this is a legally binding process, so it is important that parents use DNA paternity testing if there is any question regarding the accuracy of the given paternity claim.

Why is Establishing Paternity Important in West Chester, PA?

The benefits of establishing paternity in West Chester go far beyond establishing a biological father's parental rights and responsibilities. The legal establishment of paternity is required if either parent submits a request to receive monthly child support payments from the other parent. Furthermore, by establishing paternity, a child is provided with two legal parents, which opens the door to several benefits, including social security support, inheritance, and military benefits when possible.

Assistance Establishing Paternity in West Chester, PA

Given the various benefits of establishing paternity, it can be extremely frustrating for one parent if the other refuses to properly establish paternity. This roadblock can negatively impact the well-being of the child, especially if the parent is unable to obtain necessary child support. Luckily, a West Chester parent can file a petition to establish paternity through Chester County Family Court.

By initiating this court action to establish paternity, a judge will be able to mandate that the opposing parent completes the required steps to establish paternity. These steps will most likely include the use of DNA testing to first confirm the child's biological father. If the father is identified, paternity can then be established, and the parents may also ask for additional assistance in developing a parenting plan or requesting monthly child support services.
