What a Paternity Test Actually Measures

A paternity test compares DNA between the alleged father and the child. Because each person inherits exactly half their DNA from their biological mother and half from their biological father, the comparison is highly precise. Labs analyze specific genetic markers shared between the two samples to calculate the statistical probability of a biological relationship.

Paternity tests are used for personal knowledge, legal proceedings such as child support and custody, and immigration-related situations where biological relationships must be documented. The underlying science is the same regardless of purpose. What changes is the collection process and whether the results carry legal weight.

Strict chain-of-custody procedures are followed on every legal test, and our privacy protocols keep your information confidential throughout.

Common Reasons to Request a Paternity Test

People come to us for paternity testing across a wide range of situations. No single reason is more or less valid than another.

• Confirming biological parentage for personal peace of mind
• Establishing the legal basis for child support or custody proceedings
• Securing visitation rights
• Qualifying a child for military, government, or veteran’s benefits
• Establishing inheritance rights
• Documenting biological relationships for immigration applications
• Resolving questions about legal parenthood

Legal vs. Personal Paternity Testing

Understanding the difference between these two test types matters before you schedule. The DNA science is identical. The distinction is in how the sample is collected and what the results can be used for.

Legal Paternity Testing

Legal tests follow a strict chain-of-custody process from the moment of collection. The sample is collected at our certified facility, sealed and documented under verifiable procedures, and processed by an accredited lab. The result documentation is designed to satisfy requirements for child custody, child support, and inheritance cases in Texas courts. Home DNA kits collected outside a certified facility aren’t admissible in Texas legal proceedings, regardless of which lab processes them. If your situation involves a court, an attorney, or a government agency, a legal test collected at our McAllen center is the appropriate choice.

Personal Paternity Testing

If you’re seeking confirmation for your own peace of mind rather than for any legal proceeding, a personal paternity test delivers the same accurate results at a lower cost. These tests aren’t intended for use in court, but they answer the underlying question with the same scientific precision.

Testing for Child Support Cases

When child support is disputed, our legal paternity tests provide the court documentation typically required to move proceedings forward. A Texas court can’t order child support until paternity is formally established, and a certified, chain-of-custody DNA result is a standard way to establish it when parents disagree.

Testing Without the Mother

Including the mother’s DNA sample can improve statistical precision, but it isn’t required. We can establish paternity using only the alleged father’s and child’s samples. If the mother is available and willing to participate, including her sample can strengthen the result.
