For this purpose, we constructed an antibody array for indirect (\u201csandwich\u201d) measurement of seven serum proteins: pregnancy-associated plasma protein-A (PAPP-A), free beta subunit of human chorionic gonadotropin (f<jats:italic>\u03b2<\/jats:italic>-hCG), alpha-fetoprotein (AFP), angiopoietin-like 3 (ANGPTL3), epidermal growth factor (EGF), insulin-like growth factor 2 (IGFII), and superoxide dismutase 1 (SOD1). This array was tested using 170 DS cases and 510 matched controls drawn during the 8th\u201313th weeks of pregnancy. Data were used for prediction modelling and compared to previously obtained AutoDELFIA immunoassay data for PAPP-A and f<jats:italic>\u03b2<\/jats:italic>-hCG. PAPP-A and f<jats:italic>\u03b2<\/jats:italic>-hCG serum concentrations obtained using antibody arrays were highly correlated with AutoDELFIA data. Moreover, DS prediction modeling using (log-MoMmed) antibody array and AutoDELFIA data gave comparable results. Of the other markers, AFP and IGFII showed significant changes in concentration, although adding these markers to a prediction model based on prior risk, PAPP-A and f<jats:italic>\u03b2<\/jats:italic>-hCG did not improve the predictive performance. We conclude that implementation of antibody arrays in a prenatal screening setting is feasible but will require additional first trimester screening markers.<\/jats:p>","DOI":"10.1155\/2015\/519851","type":"journal-article","created":{"date-parts":[[2015,4,23]],"date-time":"2015-04-23T18:19:04Z","timestamp":1429813144000},"page":"1-7","source":"Crossref","is-referenced-by-count":1,"title":["Predictive Performance of a Seven-Plex Antibody Array in Prenatal Screening for Down Syndrome"],"prefix":"10.1155","volume":"2015","author":[{"given":"Jeroen L.
