The participants of the prenatal paternity test are: the pregnant mother and the alleged father of the baby . The analysis is non-invasive, which means that it poses no danger ; neither for the baby nor for the mother, since a simple blood test is necessary .
Before placing the order for a prenatal paternity test, it is advisable to organize yourself well in order to have peace of mind and above all not to waste time .
Is the prenatal paternity test dangerous?
No, the prenatal paternity test is totally safe for the mother and the baby, since a simple blood test is necessary. However, there are other invasive sampling methods such as amniocentesis or CVS (Chorionic Villus Sample), which present a risk of miscarriage.
Can a prenatal paternity test be done if the fathers are from the same family?
No, due to the way the data is analyzed, a prenatal paternity test cannot be performed reliably if the possible fathers are closely related (brothers or father/son).
Can this test be done during pregnancy twin ?
No, a prenatal paternity test cannot be performed if the mother is pregnant with twins or multiples.
Can a prenatal paternity test be legally attested?
No, in general, a prenatal paternity test cannot be considered a legal test with court-admissible results, as the collection methods are generally not performed by a licensed person. However, for the results to be legally admissible and for the names to appear on the test report, you must contact the laboratory and check if this option is offered. In this case, the possible collection of DNA from the father and mother must be certified by an approved independent third party.
Frequently Asked Questions
The conclusion of the result depends on the quantity of DNA that the laboratory will be able to use to make the comparison of DNA profiles. Thus it has been studied that in the vast majority of pregnancies, it is from the 9th week of amenorrhea that it is possible to collect sufficient genetic information from the baby in the mother's blood.
Accredited laboratories meet the requirements relating to the analysis process, management of resources and equipment, impartiality and confidentiality of information. For a paternity test, the laboratory must have ISO 17025 accreditation .
A prenatal test can confirm who the baby's father is early in the pregnancy. It then becomes an essential tool when a complicated situation can lead to an act of abortion.
For women who choose to have an abortion, the decision time is very short during which the operation can be performed, after a prenatal paternity test . As indicated, the mother can take the test when she is pregnant after the 7th week of pregnancy, the moment from from which the baby begins to grow in the placenta .
Basically, an abortion can be done as soon as the mother realizes she is pregnant, which is usually around 4 to 6 weeks into the pregnancy and the last time it can be done is usually around the 22nd. week of pregnancy . The reasons for this are that there is less risk to the mother if the abortion is performed early, rather than late. Indeed if the fetus grows, the extraction method can become a major and painful operation.
It is for these reasons that the person who wishes to do a prenatal paternity test for the purpose of a potential abortion must be well organized. In order not to waste time and have the least possible stress when considering this decision. It is advisable to make an appointment for your abortion as soon as possible even if you do not go there.
The laboratories defend themselves and do not tolerate that prenatal tests can be used for reasons of abortion.
Prenatal Paternity Test and Abortion
A prenatal DNA test can also tell you if your baby is a boy or a girl. This is a test that is always "non-invasive" and can be done during pregnancy with a blood test for the mother only.
For this test, the mother must be pregnant at least 10 weeks of amenorrhea (8 weeks of pregnancy) for the blood test.
Find out the sex of the baby
The prenatal DNA paternity test is a genetic comparison between the DNA of the fetus present in the mother's blood and that of a man in order to establish a parentage link.
This analysis determines the probability that a man is the biological father of a baby . This is a so-called "non-invasive" test that can be done during pregnancy and requires a blood test for the mother and oral swabs for the father. (exclusively)
What is a Prenatal Paternity Test?
DNA Test Participants
- The test can be done during pregnancy from the 9th week amenorrhea
To calculate amenorrhea weeks, you must count from the 1st day of the last menstrual period.
- The test cannot be performed in the following cases:
In Vitro Fertilization (IVF),
Twin or multiple pregnancies,
When the mother has cancer or preeclampsia
When the mother has received a blood transfusion, bone marrow transplant, organ transplant or stem cell treatment.
- One or more presumed fathers can participate in the test
If the father is not available for the test, you must wait until the baby is born in order to continue your paternity search.
In the event that the doubt of paternity would relate to presumed fathers coming from the same family. You cannot take this test. You need to wait for the birth of the baby and make a simple paternity test.
Preparing for the test no invasive
You must be at minimum 9 weeks of amenorrhea (7 weeks of pregnancy) for the blood test.
The longer you wait, the more likely you are to have enough of the baby's DNA in your blood to test.
Check with a healthcare professional about your weeks of pregnancy.
It happens in some mothers that the DNA of the fetus is not in sufficient quantity, even if you take the blood sample from the indicated time.
This cannot be plan and remember that genetics is a science that depends on each person's genes. If this happens to you, the laboratory will ask you to provide a new blood sample. Additional charges may apply.
When can we take the test?
You must arrange an appointment with a healthcare professional to have the blood drawn. It can be your doctor, a laboratory or a private nurse.
This appointment is your responsibility and the laboratory will not provide you with any prescription for this procedure.
Don't worry, it is always possible to find a professional who will understand your approach in order to help you with the blood test.
Oral samples from the father do not require any intervention by a healthcare professional and saliva samples can be taken at home and even kept for several weeks until the start of the analyses.
Before ordering, plan the blood test!
The analysis of the prenatal paternity test can only be carried out within 10 days from the blood test. You must therefore ensure that the blood samples are sent on the same day as the blood test .
The receipt of the kit and the sending of your samples are often included in the purchase of the test. They are usually carried out by a courier and take on average a few days to arrive at their destination.
- The deadline for receiving a kit is a few days, by international courier.
You have a tracking number and the reception must be done by a person.
- In order to return your samples, you must contact the laboratory a few days before the blood test to arrange collection. The transport to the laboratory takes a few days and you will have a new tracking number.

Prenatal Paternity Test
You can order a prenatal paternity test from your home directly on the internet . This test is mostly requested on a private basis and must be done with the assistance of a professional of health.
- Either the laboratory offers this service directly on site, or in a partner medical center
- Either the participants of the test must independently organize the blood test
Unfortunately, it is still impossible to obtain a DNA test in a pharmacy, only a laboratory with genetic analysis equipment and accredited by international standards can provide the result for a prenatal paternity test.
How to do a Prenatal Paternity Test?
The samples are (exclusively):
- Blood sample for the mother
- Saliva sample for the father(s)
You cannot use other samples for this test.
What type of sample for the prenatal test?
- 5 8 days (after receipt of your samples)
- You have the possibility to Choose an option to receive your results more quickly.
This period is calculated from the moment your samples arrive at the laboratory. Transport time is not taken into account.
What are the delays for a pregnant DNA test?
The reliability of the DNA test of prenatal paternity depends on:
- The date of the blood sample
- Sample quality
- Laboratory accreditation
- The declaration of the initial situation
- The health of the mother and the course of the pregnancy
How reliable are the results?
It is difficult to predict whether the sample that has been taken contains enough of DNA from the fetus to do the DNA test. Even if the recommendations of the laboratory indicate a possible sample from the 7th week of pregnancy, it is an average based on a set of participants and cannot reflect everyone's reality.
Every pregnancy is unique and just because your samples didn't provide enough information about the baby doesn't mean there's a problem with your pregnancy. On the other hand, if you experience a complicated or stressful pregnancy because of the situation concerning paternity, this can indeed have an influence on your relationship with the baby and reduce the exchange of genetic information that can be detected in your blood.
If your samples are not sufficient, the laboratory will ask you to take another blood sample, two weeks after the first one; fees may apply.
The DNA fragment being directly related to pregnancy and the baby, there is no risk of misdiagnosis or erroneous results due to previous pregnancies or miscarriages.
Why did my samples not work?
The results are presented in the form of a simple table with a percentage of relationship.
- Either the result is 99% , then the test is positive and the tested father is indeed the biological father of the fetus
- Either the result is 0% , then the test is negative and the tested father is not the biological father of the fetus
The results of the prenatal paternity test come in the form of a simple percentage confirming you or not the relationship. You will not have access to all the information concerning the analysis, since the sequencing technique is patented.
Yet the reliability of this test is as accurate as a simple paternity test, because the analysis technique employs a method of direct comparison between the baby's genetic fingerprint and that of the father. Prenatal paternity test results are 100% reliable for a negative result and 99.9% reliable for a positive result .
How to read the results of the genetic analysis?
The choice of laboratory is a very important step when you want to do a parentage test. You must know that each of the laboratories has specific services and depending on your situation, you must choose the laboratory that meets your expectations.
The choice of a laboratory can be made according to:
- Your family situation and available participants
- The confidence that the laboratory inspires through customer feedback
- The transparency of the company concerning its activity and your expectations
