South San Francisco CA DNA Testing Locations

Types of DNA Tests at our South San Francisco, California clinics:

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

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 South San Francisco DNA testing technicians are trained to follow these guidelines so that the results will be legally admissible.

South San Francisco, California - DNA Testing

Establishing paternity in South San Francisco, CA

Establishing paternity in South San Francisco, California is important for unmarried parents to ensure the child has a legally recognized father and can access various benefits. In South San Francisco, there are two primary methods for establishing paternity.

  1. Voluntary Declaration of Parentage (VDOP): Unmarried parents can establish paternity by signing the Voluntary Declaration of Parentage at the hospital when the baby is born. It is crucial to sign this document only if there are no doubts about paternity. Witnesses are required during the signing process, and the hospital staff can assist with the necessary steps. Once the VDOP is signed and filed, the man becomes the legal father, granting him rights and responsibilities.
  2. Court Proceedings and DNA Testing: If there are uncertainties or doubts about paternity, going to court is an option. The judge may order DNA testing to establish the biological relationship between the alleged father and the child. DNA testing is a reliable method to determine paternity. If the tests confirm the alleged father's biological relationship, the judge can establish paternity and address matters such as custody, visitation, and child support.

South San Francisco, California: Benefits of establishing paternity

Establishing paternity in South San Francisco, California offers several benefits for both the child and the father. For the child, it ensures financial support and access to health insurance. Additionally, the child may be eligible for other benefits, such as those provided to disabled or veteran children. Establishing paternity also grants the child inheritance rights and access to the medical history of both sides of the family, which can be crucial for identifying potential genetic conditions.

For the father, establishing paternity allows him to take on legal responsibilities and become actively involved in the child's life. This includes making important decisions regarding the child's upbringing and having rights to custody or visitation. Establishing paternity provides emotional bonding opportunities and a sense of connection between the father and child.

At Health Street, we provide DNA testing services to assist parents in establishing paternity. Our tests are accurate, reliable, and involve a simple cheek swab. By establishing paternity, parents can ensure the best interests and well-being of the child.
