A synergistic approach to prenatal screening

Cell-free DNA Analysis and First Trimester Ultrasound

The first trimester presents a unique window of opportunity to evaluate for fetal anomalies. Advances in ultrasound technology and maternal blood analysis via cell-free DNA (cfDNA) testing have allowed for improved first trimester (FT) evaluation for serious fetal anomalies and more accurate screening for chromosomal conditions compared to first trimester combined screening (FTCS).¹

The Voluson™ ultrasound and Harmony^® prenatal test are science-backed technologies that complement one another and enable focused and efficient guidance for maternal and fetal care.

Hear what these maternal-fetal medicine key opinion leaders (KOLs) have to say about NIPT + Ultrasound

KOLs from around the world came together at the International Society of Ultrasound in Obstetrics and Gynecology (ISUOG) meeting in 2019. Hear what these KOLs have to say about the combined value of ultrasound and NIPT in this exclusive interview.

Empowering exceptional maternal-fetal care with NIPT + Ultrasound

The Harmony prenatal test has demonstrated superiority to first trimester combined screening (FTCS) for trisomy 21 with a significantly lower false-positive rate and higher detection rate across age categories.³

However, cfDNA testing should not replace the first trimester (FT) ultrasound evaluation of a fetus but should complement it. FT ultrasound allows the detection of fetal anomalies that can be in isolation or with maternal/fetal genetic disease.⁴ Identification of ultrasound anomalies can guide pregnancy management, allowing you to provide the highest level of prenatal care to patients.

Benefits of screening with Voluson ultrasound and the Harmony test²

Excellent detection of rare and common trisomies as well as fetal structural abnormalities
Low false-positive rates, leading to a reduction in unnecessary anxiety and follow-up testing
Less complicated protocol than the contingent screening model, with almost all patients getting clear results from the first blood draw

Emerging topics in NIPT: Twins, Rare Findings and How Ultrasound Can Help

Twin pregnancies are at higher risk for complications. A combination of NIPT and ultrasound can enable efficient, accurate and early identification of the most common issues of clinical importance.

Hear fetal-medicine experts discuss evidence-based approaches to the management of twins using targeted NIPT and ultrasound, and how the emerging data is driving change in the professional society guidelines.

Early screening and diagnosis of 22q11.2 deletion can help guide pregnancy management

22q11.2 deletion is the most common chromosomal microdeletion,⁵ occurring in as many as 1 in 1000 pregnancies.⁶ First-trimester identification of at-risk pregnancies enables early confirmatory testing and can direct pregnancy management toward optimized care.

Strategic use of targeted cell-free DNA analysis and detailed ultrasound can enable early identification of fetuses at risk and allow informed management for improved outcomes.

Dr. Rabih Chaoui from the Center for Prenatal Diagnosis and Human Genetics in Berlin, Germany explains how combined ultrasound and cfDNA screening can be used to screen for 22q11.2 microdeletion.
