Analytical Comparison of Pregnancy-Associated Plasma Protein-A (PAPP-A) Immunoassays for Biochemical Determination of Gestational Age
Irina A. Buhimschi et al.
Summary: This study compared the technical characteristics of 4 commercially available PAPP-A immunoassays and tested 120 maternal serum samples to establish cutoff values at 70 days GA. The results showed that all immunoassays had sensitivities and specificities >= 80%, but there were differences in PAPP-A values depending on the immunoassay used.
