Prenatal Paternity Test
All we require to accurately confirm or exclude paternity is a sample of maternal blood 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).
The only time we cannot conduct the test is in cases of IVF, if the Mother is expecting twins or if the alleged Fathers are close blood relatives.
You can carry out our test as early as the 7th week of pregnancy (please refer to your dating scan). To calculate any dates related to your pregnancy, you may use our pregnancy calculator.
What are the advantages of non-invasive prenatal paternity testing?
1. The test is absolutely risk-free. We analyse the cell free fetal DNA found in the mother’s blood sample via a simple blood-draw. Current prenatal paternity testing sampling methods such as amniocentesis and chorionic Villus sampling (CVS) are invasive and carry the risk of miscarriage or of harming the unborn child.
2. The prenatal paternity test we offer is more cost-effective, less time consumingand 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 organize and conclude.
3. Our test does not require assistance of specialist OBGYN. Amniocentesis and CVS are medical investigations and require assistance of an OBGYN.
4. 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). See Science behind our prenatal test to understand how important this aspect is.
How does the non-invasive prenatal paternity test work?
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.
*Please note: There is currently a slightly higher wait time of 10-14 working days when submitting blood samples for the Alleged Father.
What is the Cost of the Prenatal Test?
You can carry out our test as early as the 7th week of pregnancy with results ready in just 7-10 working days from the receipt of the samples at the laboratory (or 10-14 working days when submitting blood samples for the Alleged Father). To know for how long you have been pregnant, refer to our Frequent Questions.
The cost of our non invasive prenatal test in Thailand is THB52,000 +7% VAT including the sample collection.
