Detail
Condition
Key Mechanisms
Integration of NIPT with second-trimester ultrasound soft markers (ensure this is directly supported).
Target Population
Care Setting
Key Highlights
NIPT achieved 100% sensitivity and 100% negative predictive value.
PPV improved to 83.3% when combined with high-risk ultrasound markers.
Guideline-Based Recommendations
Diagnosis
Confirm chromosomal abnormalities by karyotyping.
Use neonatal phenotypic assessment for NIPT-negative pregnancies.
Management
Consider individualized counseling based on combined NIPT and ultrasound results.
Monitoring & Follow-up
Monitor for potential false positives and the need for invasive procedures.
Risks
Invasive procedures carry a pregnancy loss risk of 0.1–0.3%.
Patient & Prescribing Data
Integration of ultrasound soft markers can refine risk assessment after positive NIPT results (ensure this is directly supported).
Clinical Best Practices
Utilize second-trimester ultrasound soft markers to enhance PPV of NIPT.
