BillionToOne Introduces UNITY Screen Revolutionizing CF Prenatal Care
Innovations in Cystic Fibrosis Prenatal Screening
BillionToOne is redefining the possibilities for families expecting a child diagnosed with cystic fibrosis (CF). The company's UNITY Fetal Risk™ Screen has emerged as a groundbreaking method, providing families with earlier and more accurate insights into fetal health. Recent research reveals significant advancements in identifying fetuses at high risk for CF, paving the way for timely interventions.
The Study's Impact and Findings
A substantial study showcased the exceptional performance of the UNITY Fetal Risk™ Screen, revealing its ability to accurately identify CF cases in a population of over 100,000 general-risk pregnant patients. This study represents the largest validation of cell-free DNA screening for cystic fibrosis to date, achieving remarkable 100% sensitivity and demonstrating a commitment to improving prenatal diagnostics.
Specifics of the Research
The retrospective analysis indicated that the test effectively identified 2,587 CF carriers, encompassing a wide range of gene variants beyond the standard F508Del mutation. Notably, the method succeeded without requiring paternal samples, addressing a common challenge in prenatal screenings.
Benefits of Early Detection
What makes the UNITY Screen particularly impactful is its potential to offer families new treatment options. An impressive 95% of the pregnancies marked as high-risk for CF were found to possess gene variants that are eligible for CFTR modulator therapy. These therapies represent a significant advancement in CF treatment options, allowing for early intervention that can improve the newborn’s overall health outcomes significantly.
Timeliness of Testing
With the capability to perform testing as early as 9 weeks into gestation, the Unity Screen promises to enhance the path to early diagnosis. A median turnaround time of 8.7 weeks ensures that expecting families can get prompt results and begin planning for necessary interventions swiftly.
Transformational Changes for Families
According to Dr. Aaron Trimble, M.D., a key figure in the study, the principle of identifying high-risk CF pregnancies early could fundamentally transform outcomes for affected infants. This advancement opens doors to promising in utero treatments, represented by emerging CFTR modulator medicines.
Advantages Over Traditional Screening
This study highlights how UNITY's single-sample approach outperforms traditional carrier screenings. By utilizing just the pregnant individual's blood, it removes barriers linked to needing a partner’s sample and provides more accurate and personalized risk assessments. This innovation brings a much-needed change from the conventional methods, ensuring better outcomes for families.

Commitment to Family Care
Dr. Haywood Brown, the Chief Medical Officer of BillionToOne, emphasized the importance of this study in addressing gaps in traditional carrier screening and reinforcing that early insights can significantly bolster families' preparedness to manage their child's health more effectively. The company's pioneering work in prenatal diagnostics holds promise for transforming care and improving lives.
Frequently Asked Questions
What is the UNITY Fetal Risk™ Screen?
The UNITY Fetal Risk™ Screen is a molecular diagnostic test designed to identify fetuses at high risk for cystic fibrosis using a simple blood sample from the pregnant individual.
How does UNITY Screen improve upon traditional CF screening methods?
Unlike traditional methods requiring both parents for optimal results, UNITY uses a single sample from the pregnant individual, minimizing logistical challenges and enhancing accessibility.
What are CFTR modulators?
CFTR modulators are breakthrough therapies designed to alleviate the symptoms of cystic fibrosis by correcting the underlying protein defects in the affected individual.
How accurate is the UNITY Fetal Risk™ Screen?
The UNITY test demonstrated 100% sensitivity in identifying pregnancies affected by cystic fibrosis, ensuring no cases were missed during the study.
Why is early screening for cystic fibrosis crucial for families?
Early screening allows families to prepare for necessary medical interventions and explore treatment options promptly, improving outcomes for the newborn.
