What Is a Prenatal Paternity Test?
Our Non-Invasive Prenatal Paternity Test is a cutting-edge test that makes it possible for you to confirm if the man you suspect to be the father of your baby is the biological father. Available from the 7th week of pregnancy, you can get the answer you need with a risk-free DNA test.
A non‑invasive prenatal paternity test is a DNA test performed during pregnancy that does not require invasive procedures like amniocentesis or chorionic villus sampling (CVS). Instead, it analyses what’s called cell‑free foetal DNA (cfDNA), which circulates in the mother’s bloodstream, to compare the baby’s genetic markers with those of the potential father.
This method is also known as a prenatal paternity DNA test or NIPPT (Non-Invasive Prenatal Paternity Test).
Our paternity DNA test while pregnant is available at one of the most affordable prices. For your convenience, you can choose to pay a 50% deposit when placing your order and settle the remaining balance when you send in your samples. Klarna and PayPal Pay in 3 payment options are also available during checkout.
How Does a Prenatal Paternity Test Work?
- Sample Collection: A simple blood draw from the mother and cheek (buccal) swab samples from the potential father.
- Isolate Foetal DNA: In the lab, technicians separate foetal DNA from the mother’s circulating DNA.
- Compare Genetic Markers: The foetal DNA profile is compared with the DNA profile from the alleged father.
- Report Results: The lab issues a report showing either a high probability of paternity (>99.9999%) or exclusion (0%).
Because this process only requires a maternal blood draw and cheek swabs, it’s completely safe for both mother and baby – there’s no risk of miscarriage from the testing itself.
When Can a Paternity Test While Pregnant Be Done?
Our non‑invasive prenatal paternity tests can be carried out from 7 weeks of pregnancy (49 days or more from the first day of the mother’s last menstrual cycle). Earlier testing can sometimes be less reliable due to the low concentration of foetal DNA early in pregnancy.
We cannot perform a prenatal paternity test for cases where the alleged fathers are close blood relatives, for incest cases, or when the mother is suffering from cancer or pre-eclampsia, or has had a recent blood transfusion, bone marrow, organ transplant or stem cell therapy.
Non-Invasive Prenatal Paternity Test Accuracy & Limitations
Our Non-Invasive Prenatal Paternity Test (NIPPT) is the most advanced and reliable way to confirm paternity during pregnancy with absolutely no risk to mother or baby.
In our accredited laboratory, highly trained specialists carefully extract the cell-free DNA found in the mother’s blood. This includes a proportion of the baby’s DNA, which is then compared to the DNA from the father’s sample.
Using cutting-edge techniques such as targeted DNA capture, library preparation, and Next Generation Sequencing (NGS), we analyse more than 1.8 million DNA base pairs across 13,000+ genetic markers (SNPs). Our expert bioinformatics team then processes this data with advanced computing systems to deliver precise results.
Before your report is issued, it is thoroughly reviewed by senior scientists to ensure the highest accuracy. Thanks to the sophistication of this technology, the test provides results with a confidence level of over 99.9999%.
Most importantly, because the test only requires a simple blood draw and cheek swabs, it is completely non-invasive and 100% safe for both mother and baby.
In summary:
- Extremely accurate (more than 99.9999%.).
- Accuracy depends on good sample collection and foetal DNA presence.
- Cannot always distinguish between very closely related males.
- It is recommended that all alleged fathers’ samples are submitted for fraternal twin pregnancies.
- A previous pregnancy does not usually affect the outcome. If pregnancy occurs within three months following a miscarriage, we recommend collecting the sample once the pregnancy has reached at least 10 weeks of gestation, as this provides more reliable results.
Prenatal Paternity DNA Test Safety & Benefits
The main advantage of this non‑invasive test is that there is no risk to mother or baby beyond a standard blood draw.
Benefits include:
- Answers and peace of mind earlier.
- Ability to plan ahead, legally or personally.
- Reduced emotional stress of uncertainty during pregnancy.
Does it Include a Baby Gender Test?
We can provide a baby gender report free of charge. Please select the option during checkout to indicate whether you want to know the baby’s gender or not.
What’s Included in the Early Pregnancy Paternity Test Kit?
The prenatal kit contains everything you need to collect your DNA samples and return them to us:
- 2 blood tubes for the mother’s blood samples
- 6 mouth swabs for the alleged father
- Instructions
- Consent forms
- Prepaid return courier pouch
The father’s samples can be collected at home without any medical assistance – the procedure is simply rubbing the mouth swabs inside the mouth and can be carried out by the alleged father himself. Please see How to Collect DNA Samples for more information,
The mother’s samples must be collected via a medical blood draw which will need to be carried out by a doctor or a nurse. It is a standard blood draw from the arm, and we can arrange for a nurse to visit you at home if you prefer not to use your own GP. There is an additional charge for this service which varies depending on location. Please Contact Us for more information and a quotation.
Once you have all samples ready, they can be returned to our laboratory using the pre-paid courier pouch included with your kit.
Prenatal Paternity Testing for Twin, IVF & Surrogacy Pregnancies
Prenatal paternity testing is available for pregnancies involving twins, IVF, or surrogacy arrangements. To ensure accurate results, please select the appropriate testing option when placing your order and provide full details of your situation before testing begins.
Twin Pregnancies
- Identical twins – standard sample collection requirements apply.
- Fraternal twins – we strongly advise that both potential fathers are tested.
IVF Pregnancies (Carrying Mother)
- Testing the father and foetus only – standard sample requirements apply.
- Testing both parents and the foetus – a minimum gestational age of 10 weeks is required.
Surrogacy Pregnancies
- Testing the father and foetus – a minimum gestational age of 10 weeks is required.
- Testing the father and egg donor – a minimum gestational age of 10 weeks is required. Samples must be provided from the surrogate mother (peripheral blood), the egg donor, and the alleged father.
If you are unsure which option applies to your situation, we recommend contacting our team to discuss your case before ordering.
Common Prenatal Paternity Testing Questions
Q: Does Prenatal Paternity Testing Work in All Pregnancies?
A: In most cases, yes however, there are some exceptions. Prenatal paternity testing cannot be carried out where the alleged fathers are close biological relatives, or in cases involving incest. Vanishing Twin Syndrome (VTS) If one embryo is lost before 8 weeks of gestation, sample collection should be delayed by a minimum of 8 weeks from that point before testing can proceed. For pregnancies involving twins, IVF, or surrogacy, please refer to the Special Cases section above for detailed guidance. If you have further questions or are unsure whether testing is suitable for your situation, don’t hesitate to Contact Us.
Q: Is a noninvasive prenatal paternity test the same as an invasive one?
A: No – invasive tests like amniocentesis or CVS carry a small risk, whereas non‑invasive tests use only maternal blood and there is no risk to the baby.
Q: Can results be used for legal purposes?
A: We offer a legal prenatal paternity test with chain-of-custody for the samples. Please Contact Us for more information.
Q: How long will I wait for results?
A: Results will be available 5-7 working days after samples are received at the laboratory.
