Collecting samples for DNA analysis is an easy and painless process that can be performed in the privacy of your own home, or at a sample collection site, if a court admissible test is required.  A sterile swab, similar to a Q-tip is rubbed on the inside of the cheek for 30 seconds, placed into an envelope and sent back to the lab for analysis.

While it is generally not necessary to obtain a DNA sample from the mother for an accurate determination of paternity, it is strongly recommended to include the mother in the test.  In a small percentage of cases, not including the mother in the test can lead to inconclusive results or a false inclusion of the father

Industry wide, paternity tests are generated using as few as four markers, to as many as 16 markers. Chromosomal Laboratories routinely uses a 16 marker test that can achieve a probability of > 99.999%.  Should a complex case arise, Chromosomal Laboratories can test an additional 5 markers, for a total of 21 genetic markers. The primary difference between a legal and private test is how the samples are collected; the laboratory testing itself is the same.

Samples for a legal test must be collected or witnessed by a neutral third party such as a laboratory, doctor, or clinic. The third party collector will use proper Chain of Custody; a documentation process used to ensure the test results are legally admissible. When your samples are collected for a legal test you will be required to show government issued photo ID. In addition, a photograph of all test participants may be taken.

• Child support
• Custody
• Inheritance

Establishing paternity means being declared the legal father after the child is born. If the parents of a child were not married when the mother became pregnant or when the child was born, the child does not have a legal father until paternity is established.

Establishing paternity is important for both the child and the parents. A child is entitled to the sense of belonging and identity that comes from knowing both parents. Establishing paternity often has an important emotional and psychological benefit for the child.

Until there is a determination that a biological father is the legal father, the child has no right to receive financial support from the father, to inherit from the father or to obtain insurance, veterans’, social security or other benefits through the father.

Likewise, until paternity is legally established, the biological father has no legal rights to the child, such as parenting time with the child, or participation in major decisions about the child, such as medical treatment, education or religious training.

DNA Collection - United States
Buccal (saliva swabs) will be collected from all parties involved. These samples will be forwarded to Chromosomal Laboratories, Inc. by the collection site (Madrigal Forensics). Test results will be av

DNA Collection - Foreign Country
Once all of the samples(buccal swabs) and necessary documentation have been received, a sample receipt email will be sent to inform you that the samples have arrived from the foreign country. Test results will be available in 2-6 business days, depending on the testing scenario. Initially, you will receive the test results by fax or email.

Final Report - Immigration Testing
Only The U.S. Government requires that the final results be received directly from the testing laboratory. Chromosomal Laboratories, Inc. will ship two notarized copies of the test results and the original photographs and documents to the USCIS office or U.S. Embassy. It is important that the test participants ensure the laboratory knows where to ship the results.

Chromosomal Laboratories, Inc will provide a Fed Ex tracking number for this shipment. The fees for this shipment will be included in the immigration handling fee.
