Myriad Genetics Launches FirstGene® Multiple Prenatal Screen
The only lab test to run four prenatal genetic screens simultaneously as early as eight weeks gestation
SALT LAKE CITY, July 21, 2026 (GLOBE NEWSWIRE) — Myriad Genetics, Inc. (NASDAQ: MYGN), a leader in molecular diagnostic testing and precision medicine, today announces the full commercial launch of FirstGene® Multiple Prenatal Screen, the only lab test that runs four prenatal genetic screens simultaneously from a single blood draw as early as eight weeks gestation.* The FirstGene screen delivers fetal chromosome screening, fetal single-gene screening, patient carrier screening and fetal RhD screening in one integrated report. The screen has greater than 98% analytical sensitivity and greater than 99% analytical specificity.1
With results expected to be delivered in approximately 10 days, the FirstGene screen is designed to help clinicians know more sooner by streamlining a historically fragmented prenatal screening process. The screen brings together multiple guideline-supported screening modalities in one order, without the need for a reproductive partner sample, helping providers deliver actionable insights for patients earlier in pregnancy.
“The FirstGene screen represents the next generation of prenatal genetic screening, using a novel approach to derive a wide range of clinical insights from a single blood sample,” said Brian Donnelly, Chief Commercial Officer, Myriad Genetics. “Providing four key prenatal genetic results with a competitive turnaround time helps clinicians make informed decisions during a patient’s pregnancy. One order. One draw. One report. Four simultaneous screens.”
The FirstGene screen integrates four distinct prenatal genetic screens into a single assay:
- Fetal chromosome screen assesses fetal risk for common chromosomal conditions, including trisomy 21: Down syndrome, trisomy 18: Edwards syndrome, and trisomy 13: Patau syndrome; sex chromosome aneuploidies; and 22q11.2 microdeletion: DiGeorge syndrome, with greater than 99% analytical sensitivity and specificity.1
- Fetal single gene screen assesses fetal risk for 19 common, actionable recessive conditions with greater than 98% analytical sensitivity and greater than 99% analytical specificity, with no reproductive partner sample needed.1
- Patient carrier screen assesses the carrier status of the pregnant individual for 20 recessive conditions, including cystic fibrosis, spinal muscular atrophy, sickle cell disease and fragile X syndrome, with greater than 99% analytical sensitivity and specificity.1
- Fetal RhD screen assesses RhD compatibility between the pregnant patient and fetus with greater than 99% analytical sensitivity and specificity for copy number variant calling.1
The FirstGene screen was developed using a rigorous, data-driven approach that included extensive analytical testing, product optimization, and performance validation. Throughout development, results were continuously evaluated for accuracy, reliability, and consistent product performance.

“As an OB/GYN, I know that in prenatal care, timing and access matter. Every additional test, blood draw or follow-up appointment can create friction for patients and providers alike and may delay access to important information that helps patients better understand their pregnancy,” said Dallas Reed, MD, Principal Medical Advisor, Myriad Genetics. “The FirstGene screen allows obstetricians to order multiple recommended prenatal genetic screens from one maternal blood sample, helping clinicians deliver more complete information earlier in pregnancy and support timely, informed conversations with patients.”
