This module calculates the risk for Trisomy 21 and Trisomy 13+18 using the algorithm provided by the the Fetal Medicine Foundation in London, UK (FMF).
The module for the First Trimester Risk calculation has exclusively been developed for the FMF and it takes full responsibility for this module. Any questions about the module should be posted directly to the FMF.
Only sonographers who have been certified by the FMF UK according to its directives and those who possess a valid FMF license may use the first trimester risk module.
Based on the detailed ultrasound examination and the maternal blood analysis and biochemistry, this module provides an algorithm that allows the calculations for fetal chromosomal defects and abnormalities in the 1st Trimester (i.e. Trisome 21) and problem pregnancies.
