Expert DNA Sample Collection Guidance from The Carlson Company
At The Carlson Company, accurate results begin with proper sample collection. This resource explains how buccal swab DNA sample collection works and why it is the preferred method for most DNA reference testing.
Our laboratory supports private individuals, attorneys, and investigators with professional DNA analysis services, ensuring that samples are handled and tested according to established forensic standards.
What Is a Buccal Swab for DNA Testing?
A buccal swab is a simple and non-invasive method used to collect DNA from cells inside the cheek. These buccal cells provide a reliable DNA source for laboratory testing, making buccal swab collection suitable for both private and forensic cases.
Buccal swab DNA testing is widely used because it is easy to collect, highly effective, and does not require blood or invasive procedures.
When Is Buccal Swab DNA Collection Used?
Buccal swab DNA sample collection is appropriate for many testing scenarios, including:
- Infidelity and relationship DNA testing
- Paternity and family relationship analysis
- Forensic and court-admissible DNA testing with documented chain of custody
- Post-mortem DNA reference samples
- Identity confirmation and investigative cases
For legal or forensic matters, The Carlson Company follows established protocols to maintain sample integrity and documentation.
How to Collect a Buccal Swab DNA Sample
To ensure reliable results, follow these DNA sample collection steps carefully:
- Use four clean cotton swabs or Q-tips.
- Locate the cheek pockets inside the mouth near the jawline.
- Apply gentle pressure and rotate the swab 6 to 8 times inside each cheek pocket.
* Two lower cheek pockets
* Two upper cheek pockets - Allow all swabs to air dry for 30 to 45 minutes.
- Place the dried swabs in a clean paper envelope.
- Label the envelope with your name and “DNA reference sample.”
Proper handling helps prevent contamination and ensures accurate DNA testing.
