Understanding DNA Testing: Legal Definitions and Implications

Definition & Meaning

DNA testing refers to the scientific analysis of deoxyribonucleic acid (DNA) to determine genetic relationships or identify individuals. DNA is the genetic material found in the cells of the human body, serving as a blueprint for biological characteristics. One common use of DNA testing is to establish paternity, as a child inherits half of their DNA from each parent. If a child's DNA does not match that of an alleged father, he is conclusively excluded as the biological parent. Conversely, a DNA test can demonstrate a probability of 99 percent or higher for confirming paternity.

Additionally, DNA testing is increasingly utilized in criminal investigations. Proper collection, preservation, and analysis of DNA evidence are vital for its effectiveness in solving cases. There have been instances where DNA evidence has led to the exoneration of wrongfully convicted individuals.

Real-world examples

Here are a couple of examples of abatement:

Example 1: A mother seeks a DNA test to confirm the paternity of her child during a custody dispute. The results show a 99.9 percent probability that the alleged father is indeed the biological parent.

Example 2: A man wrongfully convicted of a crime is exonerated after DNA testing proves that the biological evidence found at the crime scene does not match his DNA (hypothetical example).

State-by-state differences

Examples of state differences (not exhaustive):

State Paternity Testing Regulations
California Allows voluntary DNA testing without court order.
Texas Requires court approval for DNA testing in contested cases.
Florida DNA tests can be ordered by the court in paternity cases.

This is not a complete list. State laws vary, and users should consult local rules for specific guidance.
