DNA Paternity Testing


Southern California Drug Testing Clinic certified technicians can collect saliva swabs to collect a DNA specimen to be analyzed by a licensed laboratory to determine paternity and any other DNA Testing.

DNA paternity testing is a method used to determine whether a man is the biological father of a child. The process involves comparing the child's DNA profile to that of the alleged father to assess the likelihood of paternity.

Here's how DNA paternity testing typically works:

1. Sample collection: Buccal swabs (cheek swabs) are commonly used to collect DNA samples from the alleged father, the child, and, optionally, the mother. The swabs are rubbed inside the cheek to collect cells containing DNA.

2. Analysis: The DNA samples are sent to a laboratory, where the DNA is extracted from the cells and analyzed. Specific regions of the DNA, typically containing short tandem repeats (STRs), are examined to create a genetic profile for each individual.

3. Comparison: The genetic profiles of the alleged father and child are then compared to determine the likelihood of paternity. The analysis focuses on identifying genetic markers that are shared between the father and child, with the goal of establishing a high degree of probability of paternity.

The effectiveness of DNA paternity testing is extremely high when conducted by a reputable laboratory using accurate methods. The probability of paternity provided in the test results reflects the degree of certainty regarding the relationship between the alleged father and the child.

In cases where the alleged father is the biological father, the probability of paternity is typically reported as 99.9% or higher. This means that there is a 99.9% or greater chance that the tested man is the biological father of the child.

Conversely, in cases where the alleged father is not the biological father, the results will show a probability approaching 0%, indicating that he is excluded as the father of the child.

It's important to note that DNA paternity testing is considered highly accurate when performed by accredited laboratories using proper procedures. However, as with any scientific test, there is always a small margin for error, and unexpected factors such as laboratory errors or sample contamination can potentially affect the results.

Legal or Court approval DNA TEST

A legal DNA test is a type of DNA test that is performed using strict “chain of custody” procedures that first establish the legal identity of the persons being tested; the resulting report is court admissible. Typically, professional technicians collect buccal cell specimens from the inner cheeks using simple cotton swabs, and take photographs of the participants. Government issued ID is typically required.

Informational or Non-Legal Paternity DNA TEST:

A private paternity test can be collected by yourself, in the privacy of your own home, but is not admissible in court. The private paternity test is a quick, private and economical solution that is perfect for families who are seeking the truth regarding paternity for personal information.

DNA testing

People may order DNA paternity tests for various reasons. Some common reasons include:

  1. Confirmation of Biological Relationship: Individuals may want to confirm the biological relationship between a child and an alleged father. This can be important for legal and personal reasons.
  2. Legal Matters: DNA paternity tests are often used in legal proceedings, such as child custody cases, child support claims, or inheritance disputes. The results of the test can have legal implications.
  3. Peace of Mind: Some individuals may have doubts or uncertainties about the biological relationship with their child or parent. A DNA paternity test can provide peace of mind by confirming or disproving the biological connection.
  4. Immigration Purposes: In some cases, DNA testing may be required as part of immigration processes to establish family relationships for visa or residency applications.
  5. Inheritance and Estate Planning: Individuals involved in inheritance and estate planning may use DNA testing to determine biological relationships for matters related to inheritance and distribution of assets.
  6. Medical Reasons: In certain medical situations, knowing the biological relationship can be crucial for understanding genetic risks and potential hereditary conditions.

It's important to note that DNA paternity testing should be conducted through reputable and accredited laboratories to ensure accuracy and reliability of the results. Additionally, ethical considerations and privacy concerns should be taken into account when deciding to undergo such testing.
