Twin Zygosity DNA Testing in Boston
Twin Zygosity Testing Gives Boston Families a Clear Answer
Physical resemblance and details about a pregnancy don’t always establish whether twins are identical or fraternal. Twin zygosity DNA testing compares DNA from both twins to determine whether they’re monozygotic (identical) or dizygotic (fraternal).
We provide this testing through a non-invasive cheek-swab collection. Before collecting samples, we explain the available options and pricing based on whether the results are for personal information or an official purpose.

Why Families Choose to Confirm Twin Zygosity
Some families want a definitive answer to a question they’ve had for years. Others need reliable information for family records or when genetic compatibility or medical context becomes relevant.
Common reasons for testing include:
- Personal knowledge: Confirm whether twins are identical or fraternal without relying on appearance.
- Family records: Add a DNA-based answer to personal or family documentation.
- Medical context: Provide zygosity information for discussion with a qualified healthcare professional.
- Official use: Complete testing through a documented process when required by a court or government agency.
A healthcare professional should interpret the result if it could affect medical care. If an organization will receive the report, tell us before collection so we can identify the appropriate testing process.

What Happens During Twin Zygosity Testing
Our certified collectors obtain a DNA sample from each twin using a buccal swab, a small swab rubbed gently inside the cheek. The collection is non-invasive, and we explain how samples will be handled and when results are expected before testing begins.
The testing process includes:
- Test selection: We confirm how the results will be used and review any participant requirements.
- DNA sample collection: A certified collector collects, identifies, and documents a cheek-swab sample from each twin.
- Laboratory processing: We use facilities accredited by the Association for the Advancement of Blood and Biotherapies (AABB) to process DNA testing.
- Result reporting: The laboratory compares genetic markers and reports whether the findings support monozygotic or dizygotic status.
We handle testing information confidentially and maintain a clean, comfortable collection environment. Scheduled clients generally spend under five minutes in the waiting area. The full visit length and laboratory turnaround depend on the selected test and processing requirements.
Choose Personal or Official Testing Before Collection
The right collection process depends on how the result will be used. Personal testing can answer a family question, while a court, government agency, or other organization may require documented procedures.
Personal Information Testing
This option is intended for families seeking an answer for their own knowledge. Results obtained through a personal testing process might not satisfy a court or agency’s requirements.
Testing for Official Use
We follow strict chain-of-custody procedures when results are needed for an official purpose. Chain of custody documents who collected, handled, transferred, and processed each sample. Official testing may also require identity verification, an impartial collector, and specific paperwork.
Tell us how you plan to use the results before collection. We can explain the options so you don’t complete a personal test when documented procedures are required.
Arrange the Right Twin Test for Your Needs
Contact us to confirm whether you need personal or official testing, what each participant should bring, and when results are expected. We can also explain the applicable process and pricing before collecting samples.
We bring more than a decade of industry experience to DNA sample collection, and certified collectors complete every collection. Some DNA testing needs may qualify for walk-in service, but call ahead to confirm current availability and wait times.
