Figure 1

Maternal serum levels of PAPP-A throughout normal gestation and in gestations complicated by fetal aneuploidy. PAPP-A was measured using the assay developed on the Immulite 2000 analyser (Siemens, Germany) specific for the heterotetrameric complex (htPAPP-A) in the maternal serum of 7014 normal pregnancies (controls) and 96 pregnancies affected by fetal trisomy (68 trisomy 21, 21 trisomy 18, 7 trisomy 13) from 10WG to 33WG. Results are expressed in median values, and 10-90ciles for the controls.
