Non-Invasive Prenatal Paternity Test (NIPPT) uses Next generation sequencing (NGS) technique to detect the fetal genetic  information from the cell-free fetal DNA of maternal plasma. With the fetal genetic information, paternity test can be performed comparing with genetic materials of alleged father and determine the biological relationship.




  • Pregnant woman who have received blood transfusion, transplantation, stem cell therapy, immuno-therapy or with tumor disease, pre-eclampsia, triplets or more fetus, have reduced fetus from twin pregnancy, and abortion within 6 months are NOT suitable for non-invasive prenatal paternity test.
  • Surrogate or fraternal twins need to provide samples of all alleged fathers and consult customer service.
  • From the 5th week of pregnancy, the mother’s peripheral blood contains cell-free fetal DNA. However, due to differences in individual concentrations, non-invasive prenatal paternity test accept at the earliest 6 weeks. If the fetal free DNA concentration is insufficient, the reporting period may be prolonged or maternal sample may be requested for re-collection to ensure the accuracy of test. The testing period is calculated from the day after receiving the recollected sample.
  • You are responsible for the authenticity of the sample, and we are responsible for the accuracy of the test results.
  • Please follow the the sample requirements during sample collection. If the sample is not qualified (insufficient amount or volume, mixed with other sample, or contaminated, etc.) re-collection sampling may be required.
