Brief summary
The study is promoted by the Emilia Romagna Region which identified in the Bologna AUSL the coordinating center (Unità Operativa Complessa Laboratorio Unico Metropolitano, LUM, Maggiore Hospital). The medical genetics centers, participating in the technical-scientific coordination group of assessment (resolution No. 1894, 4/11/2019), the family counseling centers and the region prenatal hospital clinics are involved as collaborative experimental centers. Currently, 14,400 combined tests are carried out in the Emilia Romagna Region every year. As a result offering the new non-invasive NIPT test, it is estimated that the number of participants in the screening program will increase by up to 20,000/year. The study will collect data on the women who will access the combined test in the first 9 months of the protocol and join the enrollment.
Interventions
The test, which requires two 10 ml tubes of blood, will be performed simultaneously with the chemical biomarkers of the combined test at 10-12 weeks of gestation

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| NIPT | 9 months | Establish in which percentage invasive tests (amniocentesis and chorionic villus sampling) would be avoidable by replacing routine screening methods (i.e. combined test) with non-invasive prenatal test (NIPT). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of NIPT | 9 months | Establish a percentage of NIPT with inconclusive results |
| diagnostic performance | 9 months | Verify the diagnostic performance of the Vanadis NIPT method by verification of sensitivity, specificity, and predictive power in comparison to the combined test currently in use |
| Detection of Chromosomal Abnormalities | 9 months | Evaluate the added value of nuchal translucency for the detection of Chromosomal Abnormalities other than T21, T18, T13 |
| TAT (turnaround time) | 9 months | Evaluate TAT (turnaround time) of the NIPT and operability of the technology adopted by the laboratory |
| Validate NIPT organizational infrastructure | 9 months | Validate the organizational infrastructure for the NIPT execution in the area outside of the reference laboratory. |
