DNA Test - Lawrence, Massachusetts

Lawrence MA DNA Testing Locations

Types of DNA Tests at our Lawrence, Massachusetts locations:

The most commonly ordered DNA test is a Paternity Test to conclusively establish whether or not a man is the biological father of a child.

Paternity Testing can be performed at our testing centers. DNA Testing can be done for other close family relationships, such as:

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 people being tested. 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 registering online and shipping the specimens to us.

Legally Admissible DNA Tests vs. "Peace of Mind" At-Home Tests

Our Lawrence DNA testing technicians are trained to follow guidelines that ensure that the results can be used for legal purposes.

Lawrence, Massachusetts - DNA Testing

Massachusetts Presumption of Paternity

When a married couple has a child in Massachusetts, there's no need to establish paternity. According to Lawrence Family Law Attorneys at DiFruscia Law Offices, the man a woman is married to when a child is born is automatically deemed to be the child's legal father. However, if a couple is living together but not legally married, this rule does not apply. In this case, steps must be taken to establish legal paternity.

Voluntary Paternity Establishment in Lawrence, MA

When a child is born to unmarried parents in the city of Lawrence, and the rest of Massachusetts, the child does not have a legal father until the parents take steps to establish paternity (also called parentage). When both parents agree about the identity of the child's father, it's easy to establish paternity by completing and filing a Voluntary Acknowledgment of Parentage Form.

Once the paperwork has been processed, the man becomes the child's legal father. His name can be added to the birth certificate and he becomes responsible for providing financial support for the child. At that time, he can also petition the courts to request visitation and/or custody rights.

Establishing Paternity in Court

If both parents don't agree about the identity of a child's biological father, it's necessary to petition the courts to establish legal paternity. This can be done by the child's mother, a man who believes he is the child's father, the child themselves (even if they are under 18), and other representatives of the mother, father, or child (in certain circumstances).

Before making a ruling, the judge will typically order a DNA test, also known as a "genetic marker test," which will determine whether the man is the child's biological father. An interested party would need to file a petition for parentage in the Probate and Family Court for the county where the child and one parent lives. The court for Lawrence residents is located at 2 Appleton St, Lawrence, MA 01840.
