Prenatal Paternity Testing on Maternal Blood: Frequently Asked Questions

Has the procedure been validated by the DNA paternity testing industry?

Testing on DNA from fetal cells in maternal blood has been highly validated by the scientific community during many years as well as by a number of DNA diagnostic laboratories (see references). Our Laboratory has 16 years of practical experience in non-invasive prenatal paternity and gender DNA testing.  The Center was the first company in the world that offers a non-invasive prenatal paternity test to the general public in year 2001.

How many weeks pregnant am I?

For our testing purposes the mother is required to be at least 10 weeks gestation for Prenatal Gender testing and for Prenatal Paternity testing. If you are unsure of the exact date of conception, please add 2-3 weeks after the date of your last menstrual cycle.

Where will I go to have my blood drawn?

We will arrange for the mother's blood to be drawn at local laboratory or hospital. There may be a blood collection fee associated with the blood draw and usually range from $20-$50.

Could previous pregnancies affect test results?

Previous pregnancies will not affect your test results. As mentioned above, our testing utilizes fetal DNA which has been proven to have a short life time. This means that once the child is born the fetal DNA will degrade from the maternal blood almost instantaneously.

What if the quantity of fetal DNA is too low?

In case of insufficient DNA from fetal cells in maternal blood:  a second blood draw and re-analysis later in the pregnancy is recommended. There is no cost to re-test if the first blood draw was done at 10 weeks of gestation or later.

Is my information kept private?

Absolutely, ensuring that your information is kept safe is of utmost importance to our staff. We offer a "hold at"; location option when shipping your sample collection kit. Also, our staff will not release any of the information regarding your case without prior consent. Furthermore, if special communication requests are made we will be certain to follow them. As with any of our DNA tests we offer the option of protecting it with a password. This ensures only those with the password will be able to access information regarding your case.

How and when do I pay for the testing?

If you do not intend to come to our Laboratory to have the maternal sample collected we do require a $100.00 (US) deposit for Prenatal Gender tests or a $200.00 (US) deposit for Prenatal Paternity testing to initiate the testing process. Upon completion of sample collection there is a section on the submission form which indicates payment options. The remainder of the test can be paid with certified cheque, money order, via PayPal or with Visa, MasterCard or American Express. Unfortunately, we are unable to offer financing.

How long does it take to receive my Kit after making my deposit?

Your sample collection kits are sent usualy overnight shiping and will be delivered within 24-48 hours of receiving your order.

How long does it take to get the test results?

The results for a Prenatal Paternity test will be available on average in 9 business days after we have received your samples as this testing procedure is more in depth.

How will I receive my results?

Do you do a follow-up test for the newborn child?

Included in our testing kit is a free follow-up test. For this you may submit a sample from the newborn child. This sample will be compared to the previous alleged father samples we have on file, to complete a personal paternity test. This re-test is not only used to help clear any doubts that may remain in your mind, but has also been used to determine our accuracy rate. In the past 16 years, we have found is that the test results are approximately 99% accurate. I am ordering this test NOW!

What if I can’t get all fathers?

We understand that sometimes it is difficult to obtain samples from all of the possible fathers in your case. To make these confusing times a little easier we will also accept semen stains, toothbrushes, chewing gum, hair etc. at no extra cost. Moreover, if the fetus is male you may be able to submit paternal relatives such as the father of the alleged father, or his brothers, or other sons. Prior to submitting such a sample, please contact our Laboratory to ensure these samples are right for your case. I am ordering this test NOW!

What happens if the tested parties live in different cities or states?

We are definitely able to accommodate various situations. It is possible to send out one kit to the mother and another kit to the alleged father as well. It is important that you inform us of this situation prior to sample submission to avoid any confusion.

What is included in the sample collection kit?

Your sample collection kit will include everything you need to make sample collection a breeze! It includes the blood collection tubes and instructions for the mother, swabs and collection instructions for two possible fathers, the return shipping materials, and a follow-up test kit. If there are more than two fathers we can send more collection materials if required, at no extra charge.

What will my Prenatal Paternity results include?

The report will include a side by side comparison of the fetal and alleged father profiles, and an easy to read conclusion section telling you whether the alleged father is excluded as the biological father, or cannot be excluded as the biological father. It is also possible for us to tell you the sex of the fetus, just ask! Furthermore, as previously mentioned you will also receive a follow-up paternity test after the child is born by providing samples.

Does the testing price include a follow-up test after the child is born?

Absolutely, our Laboratory is so confident with our results that there is a follow up test after the child is born at no extra charge. For this test you are required to submit a fresh sample from the newborn child for comparison against the alleged father sample we have on file. This test is done to clear any sort of doubts that may still remain in your mind. I am ordering this test NOW!
