Brief Summary
The investigators have developed a diagnostic test for the evaluation of the presence of fetal malformations through metabolomic analysis of maternal peripheral blood serum by chromatographic techniques and mass spectrometry, and subsequent mathematical modeling analysis of the data by means of multivariate mathematical models specifically developed for this purpose. The study aims at determining the performance parameters (specificity, sensibility, positive predictive value (PPN), negative predictive value (NPV), etc.) of the test and its applicability. To do this, the investigators will use the serum samples of the patients enrolled in New Zealand in the SCOPE Study (www.scopestudy.net), an international study conducted between years 2004-2008.

Outcome Measures
Primary Outcomes (2)
Diagnostic test performance evaluation in dichotomic classification at 19-21 weeks' gestation
Assessment of the sensitivity, likelihood ratios and performances (diagnostic accuracy) in the identification of a malformed fetus through the analysis of a serum sample from a mother at 19-21 weeks' gestation
6 months
Diagnostic test performance evaluation in the individuation of the exact diagnosis of fetal malformation at 19-21 weeks' gestation
Assessment of the sensitivity, likelihood ratios and performances (diagnostic accuracy) in the identification of the type of malformation through the analysis of a serum sample from a mother at 19-21 weeks' gestation

Secondary Outcomes (2)
Diagnostic test performance evaluation in dichotomic classification at 14-16 weeks gestation
6 months
Diagnostic test performance evaluation in the individuation of the exact diagnosis of fetal malformation at 14-16 weeks gestation

Study Arms (2)
19-21 weeks' gestation
The test validation will be performed on the 1943 serum samples of pregnant women at 19-21 weeks' gestation recruited in New Zealand for the SCOPE Study. All the samples will be analyzed to extract and purify the whole metabolome. Metabolites will be characterized through mass spectrometric techniques. These data will be interpreted by means of a bioinformatic algorithm specifically designed for this purpose.
14-16 weeks' gestation
Five hundred subjects at 14-16 weeks gestation were randomly selected from the whole cohort of patients. The serum samples collected at 14-16 weeks gestation will be used to test the diagnostic performance at this earlier gestational phase.
Interventions
The serum samples will be used to get a metabolomic profile

Data Sharing
- IPD Sharing
- Will share
Test validation of the screening technique will be conducted blinded. The investigators will have access only to the serum samples identified by their unique ID. At the end of the analytical phase, the database containing results will be locked. The database will be transferred to an independent investigator (Prof. Alessio Fasano at Mass General Hospital for Children, Boston, USA) for data analysis. At the same time, information related to pregnancy outcomes (in terms of presence or absence of fetal anomaly) will be transferred from the University of Auckland to the Mass General Hospital for Children, which will provide the blind break and will procced to the estimation of the test performance.
