Non-Invasive Prenatal DNA Paternity Testing

What is non-invasive prenatal DNA paternity testing and how is it performed?

Non-invasive prenatal DNA paternity testing is unique in that paternity of an unborn child can be determined as early as 8 weeks after conception without an invasive and often dangerous procedure being performed on the mother and the fetus.

Non-invasive prenatal paternity testing is performed by collecting a DNA sample from the cheeks of each alleged father using a sterile buccal swab and a blood sample from the mother.

Who should choose non-invasive prenatal DNA paternity testing?

Non-invasive prenatal DNA paternity testing is typically performed for individuals and families who cannot or would rather not wait for the child to be born or who would rather not undergo invasive and often dangerous procedures such as Amniocentesis or Chorionic Villus Sampling (CVS).

Prenatal DNA paternity testing cannot be performed if the mother is carrying multiples (twins, triplets etc...). In these cases, postnatal DNA paternity testing should be considered.

Prenatal DNA paternity testing is admissible in legal proceedings where paternity of the child is in question.

How we can help.

We can provide confidential and court admissible prenatal DNA paternity testing services. Our laboratory uses only the most advanced scientific methods and DNA high-sequencing instruments available.

In situations where donors are living in other states or even overseas, we can coordinate the collection of their samples where each donor resides.

Frequently Asked Questions
Do I need an appointment for Prenatal DNA Paternity Testing?

Yes. Appointment are required.

Can the test results be used in legal proceedings?

Yes.

The alleged fathers are brothers or close relatives, is the test still accurate?

Yes. If there are two or more possible fathers and they are brothers or close relatives, testing is still accurate. We need to know this ahead of time so that additional testing can be performed at the laboratory. Identical twins cannot be tested accurately.

I'm not certain how many weeks along I am. Can I still take the test?

The DNA of the fetus can be reliably detected in the mother's blood as early as 8 weeks after conception. If you aren't certain how many weeks pregnant you are, we recommend that you wait at least 8 weeks after your last known menstrual cycle. If you are still uncertain or your cycles are irregular, we recommend that you contact your primary care physician for help determining your estimated date of conception before ordering the test.

How long will the collection take?

Typically collections take between 30 minutes to an hour depending on the number of donors.

How long before I get my results?

Once all necessary donors have been collected results are usually available in as early as 7 business days. Some results may take up to 10 days before they are available.

Is this a blood test?

We use buccal swabs on the inside of the mouth to collect DNA from cells on the cheeks of the alleged father(s). The mother is required to provide a blood sample for testing.

If the mother is a minor, can she consent to testing?

Mothers who are minors at the time of testing cannot consent to their own testing unless they have been legally emancipated and can provide the necessary documents proving the emancipation. A parent or legal guardian must sign for the mother in these instances.

If the alleged father is a minor, can he consent to his own testing?

Alleged fathers who are minors at the time of testing cannot consent to their own testing unless they have been legally emancipated and can provide the necessary documents proving the emancipation. A parent or legal guardian must sign for the alleged father in these instances.

Is it possible to determine the gender of the child at the time of testing?

At this time we are not able to provide gender determination as part of this test. This may be something we provide in the future.

Is it possible to know when other donors make their appointments?

No. Appointment information is confidential and is not provided to anyone other than the person who made the appointment.
