Paternity For Life

Non-Invasive Prenatal Paternity DNA Test

Non-Invasive Prenatal Paternity DNA Testing can be used to confirm the paternity of a child before it is born. This can be useful in situations where a woman has had multiple partners in the month of conception and would like to know who the father of the child is before the child is born, or to assist with making decisions regarding their personal relationships.

Safe and Accurate

During pregnancy, fetal DNA is present in maternal blood and paternity can be determined via sequencing and analysis of cell-free fetal DNA extracted from maternal blood. This ONLY requires a blood sample to be taken from the mother, which is much safer for both the mother and the unborn child. Other prenatal DNA testing methods can be invasive, and can come with risks such as miscarriage and leakage of amniotic fluid.

Our DNA test is highly advanced, and the most accurate on the market. It analyses over 5,000 genetic markers, known as Single Nucleotide Polymorphisms (SNPs), to determine paternity with 99.9% accuracy. We are also able to test more than one alleged father at an additional cost.

Prenatal paternity DNA testing is for “peace of mind” purposes only and are not admissible in a court of law. Most courts will require paternity DNA testing to be performed after the baby has been born to confirm paternity.

How many weeks pregnant do I need to be?

Our Non-Invasive Prenatal Paternity DNA Test is validated from 7 Weeks Gestational Age. However, optimal testing is from 10 Weeks Gestational Age (this means you will be in your 10th week of pregnancy, starting from the first day of your last menstrual period). If you provide a sample too early, or you have incorrectly calculated your gestational age, there will not be enough fetal DNA for us to perform DNA testing. This is why optimal testing is from 10 weeks gestational age. In these cases we will request a recollection at a later gestational age, to ensure there is more fetal DNA in the mother’s blood. To determine your gestational age contact us or your doctor.

Collection Process

For DNA testing we require the following samples

  • 1 x 10 mL blood sample from the mother
  • 1 x 10 mL blood sample from the alleged father

Please be advised that due to COVID-19 we are now temporarily also collecting a blood sample from the Alleged Father for Non-Invasive Prenatal Paternity Testing instead of a mouth swab. Please contact us if you have any questions. 

Upon receiving your application and payment, Paternity for Life will send a collection kit to your nominated address. The kit will contain everything needed for you to collect your samples and return to us. You will need to take your DNA testing kit to your local doctor or pathology centre to have the samples collected. Please note, there may be an additional collection fee charged by your doctor or pathology centre.


Upon receiving your samples at our laboratory, we will promptly begin processing. We endeavour to have your results to you within 10 – 15 working days from receipt of your samples at our laboratory.

If you have any questions regarding Non-Invasive Prenatal Paternity DNA Testing, please see our NIPPT FAQ’s or contact us.

Please Note

There are some situations in which non-invasive prenatal paternity DNA testing is not suitable. For example, if the mother is suffering from cancer, toxaemia of pregnancy or has had a blood transfusion, bone marrow or organ transplant, or stem cell therapy.

If the child has been conceived through IVF, is being born via surrogacy, or if it is a twin pregnancy, prenatal paternity DNA testing can still be done but the samples required for DNA testing may be different. Please see our NIPPT FAQ’s or contact us to discuss your particular case.
