Aneuploidy Risk Calculator
About the Aneuploidy Risk Calculator
The Aneuploidy Risk Calculator is a scientifically validated, peer-reviewed tool that accurately estimates the risk of trisomy 21, 18, and 13 using the FMF first-trimester screening algorithm — the global gold standard used in over 100 countries. It combines maternal age, nuchal translucency (NT), and biochemical markers (PAPP-A, free β-hCG) to provide individualized risks. Learn more at Aneuploidy Risk. Proudly supported by Agri Care Hub.
Why Aneuploidy Screening Is Essential
Aneuploidies affect 1 in 600 live births and are the leading cause of pregnancy loss. Early, accurate risk assessment empowers informed decision-making, reduces anxiety, and optimizes resource allocation for diagnostic testing.
How to Use the Calculator
- Enter maternal age at time of delivery
- Input gestational age at scan
- Enter NT measurement (crown-rump length adjusted)
- Enter PAPP-A and free β-hCG MoM values
Scientific Algorithm (FMF/Nicolaides)
Risk = Baseline Risk × Likelihood Ratios (NT + Biochemistry)
Applications
- Prenatal counseling
- First-trimester screening
- Research & training
