Frequently Asked Questions

Is it hard to perform? 

  • We take a blood sample from the mother’s arm, this will contain free-floating fetal DNA cells (cfDNA)

  • The baby’s DNA profile is checked against a cheek swab sample from the possible father

  • Next-generation sequencing (NGS) is used to assess the probability of paternity

What will my test results say?

  • The tested male cannot be excluded as a biological parent - this means there is a 99.9% chance that the tested male is the baby's father

  • The tested male was excluded as a biological parent – this means the tested male is not the baby's father

  • Uninformative result – this means we cannot determine whether the tested male is the baby's father. In the event of an inconclusive result, we will request another sample. There is no extra charge for this.
