Effect of Preanalytical Factors on the Stability of Maternal Serum Biomarkers and Calculated Risk for Trisomy 21, Trisomy 18, and Open Neural Tube Defect
Biochemical prenatal screening tests are used to determine the risk of fetal aneuploidy based on the concentration of several biomarkers. The concentration of these biomarkers could be affected by preanalytical factors (PAFs) such as sample type (whole blood vs serum), storage time, and storage temperature. The impact of these factors on posttest risk is unknown.
