The earliest timing for Non-Invasive Prenatal Paternity Testing depends on the laboratory's testing requirements. Many NIPP programs can be performed relatively early in pregnancy because fetal DNA is present in the mother's bloodstream.
Why Timing Matters
Laboratories require sufficient fetal DNA to perform reliable analysis.
Factors Affecting Eligibility

Frequently Asked Questions
Can testing be performed in the first trimester?
Yes. 8 weeks gestation is preferred.
Why do laboratories have minimum pregnancy requirements?
Adequate fetal DNA must be available for analysis. Fetal (or baby) dna roughly doubles every week and 8-10 weeks is usually when there is adequate free floating baby dna in mother's blood for the lab to do the analysis.
Is testing available throughout pregnancy?
Yes. But most patients do this around 8-10 weeks of their pregnancy.
