Twin Zygosity Testing in Alexandria
Non-Invasive Twin Zygosity Testing for Clearer Answers
When appearance or placental information isn’t conclusive, twin zygosity testing can provide a clear answer. This DNA comparison determines whether twins are monozygotic, commonly called identical, or dizygotic, commonly called fraternal.
Each twin provides a non-invasive cheek swab, also known as a buccal swab. Comparing their DNA markers offers a more dependable answer than relying on appearance alone, whether the twins are infants or adults.

“
To the Fastest Labs Management and anyone concerned with the above and beyond behavior I was given in your Alexandria office on 6/21/23. It started when Jabria answered the phone on my initial inquiry. I had a lot of questions and although being relatively new, she never got flustered and was ALWAYS polite in responding to my many questions! She is an A+ employee and her people skills are A+!
I didn’t have the opportunity to talk to Alicia before my visit, but when I arrived at the office she was just as professional as Jabria, and A+ team.
Thanks for making sure I get a value for the dollars I spent, and a special thanks to Jabria and Alicia!

How the Twin Zygosity DNA Test Works
We begin by confirming which test fits your reason for testing. Before collecting samples, our collectors explain the requirements, available documentation, and how you’ll receive the results.
The testing process generally includes:
- Confirming Requirements: We discuss whether you need the test for personal information or require documented collection and reporting.
- Collecting Samples: A collector uses a cheek swab to obtain a DNA sample from each twin.
- Sending Samples for Analysis: We send the samples to a partner facility for laboratory processing.
- Communicating Results: We provide confidential results after the laboratory completes its analysis.
Timing depends on the test ordered, laboratory processing, and documentation requirements. Ask about the expected timeline when scheduling.
Why Families Request Twin DNA Testing
Families may seek zygosity results for personal knowledge, family records, medical history discussions, or questions about genetic compatibility. The result identifies whether twins are monozygotic or dizygotic, but it doesn’t diagnose a medical condition or replace guidance from a qualified medical professional.
Before booking, consider these practical questions:
- Can both twins attend the sample collection?
- Will a parent or legal guardian need to participate if the twins are children?
- Is the result for personal information, or is documented collection required?
- How will the confidential results be delivered?
- What documentation should you bring to the appointment?
