First-trimester screening for trisomy 21 by free beta-human chorionic gonadotropin and pregnancy-associated plasma protein-A: impact of maternal and pregnancy characteristics.
OBJECTIVES To use multiple regression analysis to define the contribution of maternal variables that influence the measured concentration of free beta-human chorionic gonadotropin (beta-hCG) and pregnancy-associated plasma protein-A (PAPP-A), and the interaction between these covariates, in first-trimester biochemical screening for trisomy 21. METHODS This was a multicenter study of prospecti...
متن کاملEffect of temperature on free beta-human chorionic gonadotropin and pregnancy-associated plasma protein-A concentration.
OBJECTIVE To examine the effect of the duration of storage of serum and whole blood at different controlled temperatures on the concentrations of both serum free-beta-human chorionic gonadotropin (beta-hCG) and pregnancy-associated plasma protein-A (PAPP-A) in first-trimester screening for aneuploidies. METHODS The concentrations of free beta-hCG and PAPP-A were measured in samples collected ...
متن کاملComparison of First Trimester Screening for Down’s Syndrome Using Free Beta-Human Chorionic Gonado-tropin and Pregnancy-Associated Plasma Protein-A Levels between Spontaneous and IVF Pregnancies at 12 Weeks of Gestation
Objective The purpose of this study was to compare Free Beta-HCG and PAPPA levels in single normal and under IVF pregnancies 11-13w + 6d of gestational age. MaterialsAndMethods In this observational study that was performed as a cohort, 300 consecutive single IVF pregnancies and 700 single normal pregnancies were enrolled about 11-13w + 6d of gestational age and Free Beta-HCG and PAPPA was comp...
متن کاملA molar pregnancy detected by following beta-human chorionic gonadotropin levels after a first trimester loss.
This case report summarizes the sequence of events that led to the detection of a molar pregnancy missed by ultrasound and initial pathology examinations. This patient illustrates that following serial quantitative beta-human chorionic gonadotropin (B-hCG) levels after spontaneous, therapeutic, and elective abortions will help detect potentially life-threatening molar and ectopic pregnancies. F...
متن کاملfirst trimester screening using ultrasound and serum markers in panamanians: factors associated with adverse pregnancy outcomes
background: there is no published data on the association between serum biochemical and ultrasonographic markers and adverse pregnancy outcomes. therefore, the aim of this study was to determine the factors associated with perinatal outcomes in singleton pregnancies using ultrasound and maternal serum markers during the first trimester in panamanians. materials and methods: this was a prospecti...
