How does it work?

All we need in order to accurately prove or disprove paternity is a maternal blood sample and either a blood sample or mouth swab samples from the alleged father (Blood Samples are preferable for the Alleged Father where possible).

*if the probability that the alleged father’s DNA contains the genetic markers required of the biological father is greater than 99.9% when compared to random individuals, paternity is concluded. If the alleged father matches no better than an unrelated individual, paternity is excluded.

You can carry out our test as early as the 10th week of pregnancy (8 weeks post conception).

What are the Advantages of Non-invasive Prenatal Paternity Testing?

  • The test is absolutely risk-free. We analyse the cell free fetal DNA found in the mother’s blood sample which is taken via a standard medical blood-draw just like with any normal blood test. Alternative prenatal paternity testing sampling methods such as amniocentesis and chorionic Villus sampling (CVS) are very invasive and do carry the risk of miscarriage or of harming the unborn child.

 

  • Our test does not require assistance of specialist OBGYN. Amniocentesis and CVS are medical investigations and require assistance of an OBGYN.

 

  • The prenatal paternity test we offer is cost-effective, less time consuming and simple to carry out. The medical costs of undergoing invasive sample collections like amniocentesis or Chorionic Villus sampling can be relatively high and can take longer to organise and conclude.

 

  • Because we use cell-free DNA in the maternal blood, there is no risk of misdiagnosis or incorrect results due to previous pregnancies or miscarriages. It is important to note that because we use cell-free fetal DNA, our prenatal test is far more accurate and reliable than other non-invasive tests that use whole DNA enclosed in cells (nucleated fetal Cells).

 

  • Scientists have for long known that fetal DNA is present in maternal blood during pregnancy.  The NIPPT (Non-Invasive Prenatal Paternity Testing) is performed using NSG (Next Generation Sequencing) technology.

What is the difference between Blood and Mouth Swabs for the Alleged Father?

We can test using Mouth Swab Samples from the Alleged Father however we prefer a blood sample where possible. This is just through a simple blood draw from the arm as with any normal blood test. When providing swabs, we are able to examine 2,688 SNPs in order to make a determination of paternity.

With Blood, we are testing a larger number of SNPs – over 5,000 compared with 2,688 – this requires more DNA than what would consistently and effectively convey if we used saliva and means we are able to test with more accuracy.

*Please note: There is currently a slightly higher wait time of 10-14 working days when submitting blood samples for the Alleged Father.

Prenatal Paternity Testing and Baby Gender

If you opt to use blood samples for alleged father instead of mouth swabs, we can even confirm the gender of the baby for an additional $100.

Our Gender determination is only available with our non-invasive prenatal paternity testing when blood is provided for the alleged father.

It is important that you add this service to your order at the checkout if you would like to know your baby’s Gender as it CANNOT be added once your kit has been dispatched.

What is the Cost of the Prenatal Test?

You can carry out our test as early as the 10th week of pregnancy (8 weeks post conception) and results can be available in as little as just 7-10 working days from the receipt of the samples at the laboratory.

The cost of our non invasive prenatal test is just $1595.00 including the sample collection!

Our test is the most accurate non-invasive pregnancy test for paternity, available worldwide.

FAQs

Will the test results indicate the gender of the child?

We offer you the option of establishing the gender of the baby with our prenatal paternity test. If you opt to use blood samples for alleged father instead of mouth swabs, we can even confirm the gender of the baby for an additional $100.

Our Gender determination is only available with our non-invasive prenatal paternity testing when blood is provided for the alleged father.

It is important that you add this service to your order at the checkout if you would like to know your baby’s Gender as it CANNOT be added once your kit has been dispatched.

Should I test both fathers?

If the samples for both fathers are available we strongly advise you to send samples for both fathers. There is an additional fee for testing the second father. If the father lives in a different location, Genetic Testing Laboratory can send out a separate kit. There will be a small added fee in such cases.

What samples are collected from the alleged father?

This test can only be done with blood samples for the mother. We require mouth swab samples for the father. We are unable to carry out this test with any other type of sample. GTL provides you with a complete kit. Just fix an appointment with any nurse, lab technician or phlebotomist for the venal blood draw.

How many weeks pregnant must I be to take the test?

The expectant mother must be in at least her 10th week following her last menstrual cycle. We cannot directly assist you in confirming how many weeks pregnancy you are but we can guide you to a pregnancy calculator.

How do I collect my samples?

GTL sends out all prenatal testing kits by express delivery. The kit contains sterile, vacutainer plastic tubes which will hold the mother's blood samples. Blood is drawn directly from the vein as happens with any standard blood draw. Ensure the blood collection is carried out by a qualified nurse or phlebotomist. You will be provided with 2 tubes for the mother’s blood. Both tubes provided need to be filled. The alleged father's samples are collected using sterile mouth swabs. Instructions and consent forms are also provided inside the kit. The kit has a special biohazard label which means your kit is also suited for shipping and transport of biological substances.

The non-invasive prenatal paternity test includes a pre-paid courier service for return of samples to our laboratory. Contact the number provided and arrange an appointment to have your samples collected. Ideally, organise the collection of your samples on the same day as the blood draw.
