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.

Yorba Linda, California - DNA Testing

Establishing paternity in Yorba Linda, CA

In Yorba Linda, California, establishing paternity is essential for unmarried parents. Doing so can ensure they each have rights and responsibilities for the child, and that the child does not miss out on any benefits. The process of establishing paternity can be done by signing a Declaration of Paternity (DOP) or by going to court.

If parents are unmarried and have no doubts about paternity, they can choose to sign the Declaration of Paternity. Typically, this document is signed at the hospital, with the assistance of the staff. However, it is crucial to only sign the DOP if there are no reasons to doubt the biological fatherhood. If there are any concerns about paternity, seeking court intervention may be a better option. Going to court often involves DNA testing, which is a reliable method for proving paternity. The judge can establish paternity if the DNA tests confirm the alleged father's biological relationship to the child. After paternity is established, the court can also establish custody, visitation hours, and child support if necessary.

Yorba Linda, California: Challenging paternity

There are various ways to challenge paternity in Yorba Linda, CA. If you are not married to the child's mother, you can challenge presumed paternity. In most cases, challenging paternity involves DNA testing. If the DNA test results demonstrate that you are not the biological father, you may be able to challenge paternity. If the DNA test confirms that you are the birth father, however, you will have certain rights and responsibilities that come with paternity. It is important to note that challenging paternity after it has already been established can be a complex process.

Health Street's DNA testing services can help parents establish paternity. Our tests are 99.9% accurate and involve a simple cheek swab, making the process quick and painless.
