The non-invasive test can only be done during pregnancy and poses no danger ; neither for the baby nor for the mother, since a simple blood test is necessary. 

- The test can only be done from the 10th week  of amenorrhea.  Amenorrhea weeks are calculated from the 1st day of the last menstrual period.

- The test cannot be performed in the following cases:

 

Twin or multiple pregnancies,

When the mother has cancer or pre-eclampsia  

When the mother has received a blood transfusion, bone marrow transplant, organ transplant or stem cell treatment

If the fetus has a structural abnormality

How quickly can I get my kit and is delivery included in the price?

All shipping costs are included in the price of the kit. The kit is sent to you via an express shipment of up to 4 days and it includes the documents for the transport to return your sample to the laboratory.

Frequently Asked Questions

Before placing the order for a prenatal baby sex test, we advise you to organize yourself well in order to have peace of mind and above all not to waste time . 

The conclusion of the result depends on the amount of DNA that the laboratory will be able to use to detect the Y chromosome. Thus it has been studied that in the vast majority of pregnancies, it is from the 10th week of amenorrhea that it is possible to collect enough genetic information from the baby in the mother's blood.

Accredited laboratories meet the requirements relating to the analysis process, the management of resources and equipment, the impartiality and confidentiality of information. For a DNA test the laboratory must have
ISO 17025 accreditation .

A prenatal DNA test can also help if you are in doubt about the paternity of the baby.  This is a test that is always "non-invasive" and can be done during pregnancy with a blood test for the mother and a saliva test for the alleged father.

For this test, the mother must be at least 9 weeks pregnant (7 weeks pregnant) for the blood test.

The procedure and organization remains similar to the baby sex test and you have the option of placing an order grouped with the paternity and sex of the fetus.

Know the father of the baby

The prenatal DNA test allows you to find out from the start of pregnancy whether your baby is a boy or a girl .  This is a so-called “non-invasive” test and requires a simple blood test for the mother.

What is a test to find out the sex of the baby ?

The reliability of the DNA test  Prenatal depends on several factors:

- The date of the blood sample

- The quality of the samples

- Laboratory accreditation

- The health of the mother and the course of the pregnancy

How reliable are the results ?

DNA Test Participants

Preparation for the test non invasive

weeks-pregnancy-non-invasive

 

You must be at  minimum 10 weeks of amenorrhea (8 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 do the blood test from the indicated moment.


This cannot be  to expect  in advance and  remind  you 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?

doctor-appointment-blood-collection

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, you will always 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 professional intervention and saliva samples can be taken at home and even kept for several weeks until the start of the analyses.

Before placing the order, organize the blood test!

sample-shipment-laboratory

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.

The prenatal DNA test to find out the sex of your baby is  detection of Y chromosome present in the mother's blood .  

Remember that the Y chromosomes are genes transmitted only from father to son on an entire male line. A daughter receives from these two parents only the genes of X chromosomes. The mother by  nature  does not have a Y chromosome in his body.

So if the laboratory:

 

- Detects the presence of Y chromosome in the blood:  the fetus is a boy

- Does not detect the presence of  chromosome  Y in the blood: the fetus is a girl

How does the test work during pregnancy ?

 

The test to find out the sex of the baby is a very precise analysis which requires great rigor in respecting the sampling instructions. So to ensure an optimal and fast result, please follow these precautions:

- The blood test must be carried out exclusively by a woman

- No male person should handle the blood tubes (before and after sampling)
- Take blood test on an empty stomach
- Be at the right time of your pregnancy

 

The conditions concerning the samples for this test make it possible to avoid the risks linked to the nature of the analysis. Like a contamination by a man, of the Y chromosome of your samples. This can completely distort the results.

 

Also, if you do a test before the indicated period, you risk not having enough fetal DNA present in the blood for the laboratory to make the detection. Taking this risk may give you a false result . Because the non-detection of the Y chromosome due to a too low presence rate will lead to the determination that the fetus is a girl when it is possible that it is a boy.

What are the sampling precautions?

Sample types are exclusively:  

- Blood sample for the mother

You cannot use other samples for this test.

What type of sample for the prenatal test?

- 5 to 8 days (after receiving your samples)

- You have the possibility to choose an option in order to receive your results more quickly.

 

This time is calculated from the moment your samples arrive at the laboratory.  Transport time is not taken into account.

What is the timeframe for a pregnant DNA test ?


It is difficult to predict in advance whether the sample that has been taken contains enough DNA from the fetus to do the DNA test.  Even if the laboratory recommendations indicate a possible sampling from the 8th week of pregnancy, it is an average based on a group of participants and cannot reflect the reality of each one.
 

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, this can indeed influence 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.

How to read the results of genetic analysis ?

The results are presented in the form of a simple table showing the confirmation of the sex.

- Either the result is positive , the Y chromosome has been found, which confirms that the fetus is a boy

- Either the result is negative , the Y chromosome was not found, which confirms that the fetus is a girl

The reliability of this test is 98% accurate if all sampling precautions have been respected.

How to read the results of genetic analysis ?


The choice of laboratory is a very important step when you want to do a DNA test. You should know that each of the laboratories has specific services and depending on your situation it is obvious to make the choice that suits you.

The choice of a laboratory can be made according to:  

​​

-  Trust  that the laboratory inspires through customer feedback
