DNA testing a child typically involves collecting DNA samples from the child, and often from the alleged parents, and sending them to a lab for comparison. Here's a breakdown of the process:
DNA Sample Collection
The most common and non-invasive method involves:
-
Swabbing the Cheek: A cotton-tipped swab is gently rubbed on the inside of the child's cheek (and the cheek of the mother and/or father). This collects cells containing DNA.
- Example: Imagine a parent carefully and gently swabbing the inside of their child's cheek, ensuring good contact to collect enough cells for accurate testing.
Sending Samples to a Lab
- Packaging: The swabs are carefully packaged to prevent contamination.
- Shipping: The samples are then sent to a certified DNA testing laboratory.
DNA Analysis and Comparison
- DNA Extraction: In the lab, DNA is extracted from the cells collected on the swabs.
- DNA Profiling: A unique DNA profile is created for each individual.
- Comparison: The lab compares the DNA profiles of the child, mother (if included), and alleged father to determine if there is a match.
Reporting the Results
The lab provides a report indicating the probability of parentage based on the DNA comparison. This report is generally easy to understand.
