Maternity test – Premium Duo examination

Premium maternity test: 31-marker Duo test
The DNA Center's 31-marker Duo maternity test provides the highest level of accuracy in determining biological relationships. This test examines the DNA of the child and the alleged mother, making it especially useful in cases where the standard 24-marker maternity test does not provide sufficient evidence. The analysis of 31 markers enables a more precise determination of biological maternity, even in complex cases.

When is the 31-marker maternity test recommended?

The 31-marker Duo maternity test is ideal in the following cases:

• Complex genetic scenarios: When the standard 24-marker test does not yield clear results, the 31-marker test ensures higher accuracy in establishing biological maternity.
• Cases requiring greater precision: In situations where determining the relationship is critical (e.g., legal cases), the 31-marker test provides more definitive results.

How is the sample collected?

The test does not require a laboratory visit; sample collection can be done conveniently at home. When the test is ordered, the DNA Center sends specialized sample collection kits via mail. Sample collection is painless and typically involves obtaining a cheek swab from each participant.

Steps for sample collection:

• Use the provided swab to gently rub the inside of the cheek (buccal mucosa), rotating the swab several times to collect cells.
• Place the swabs into the labeled sample envelope as per the included instructions.
• Return the samples, along with the completed data form and proof of payment, to the DNA Center by regular or priority mail to the address provided in the instructions. Alternatively, samples can be delivered in person to our office.

What does the sample collection kit include?

• Sampling tools for the number of participants in the test.
• One pre-labeled sample envelope per participant.
• A data form to be filled out, signed, and returned with the samples. The form should include details such as the type of test requested, participant information (name or alias, and optionally date of birth), the date of sample collection, and instructions on how and where the results should be sent (email or postal address). The form should also include the payer's name and address for invoicing purposes.
• Detailed guidance on the process (instructions for sample collection and form completion, including the return address and payment information).
• A yellow postal check if postal payment is chosen.

Why choose the 31-marker Duo maternity test?

The 31-marker Duo maternity test provides greater accuracy in determining biological relationships, particularly in complex genetic cases. The additional markers ensure more precise results, minimize the potential for errors, and deliver reliable outcomes, even in legal proceedings.
