Prenatal Genetic Testing

Prenatal testing for faster, clearer answers

From CMA to exome and genome testing, we deliver answers with the largest rare disease and prenatal exome dataset, GeneDx InfinityTM.1

The right genetic test can change everything

Our suite of prenatal tests helps you uncover answers with precision and speed without needing to work with multiple labs or collect multiple samples.

CMA

Use when: Abnormal serum screening, non-diagnostic karyotype, and fetal ultrasound anomalies suggest deletion and duplication syndromes

Turnaround time: ~2 weeks


Available for
proband

ExomeDx™ Prenatal

Use when: Fetal anomalies are detected via ultrasound and CMA and karyotype are non-diagnostic.

Turnaround time: within 2 weeks


Available for
proband, duo, or trio

GenomeDx™ Prenatal

Use when: Complex or unexplained fetal anomalies are detected via ultrasound and CMA and karyotype are non-diagnostic, and comprehensive genomic analysis is needed.*

*GenomeDx Prenatal is currently not available in New York State.

Turnaround time: within 2 weeks


Available for
proband, duo, or trio

Targeted Panels: Use when a specific condition is strongly suspected and CMA and karyotype are non-diagnostic. Turnaround time: 2-3 weeks
