Effect of fetal gender on first trimester markers and on Down syndrome screening. But how can I tell if I'm producing hCG? Multiple imputation for missing data in epidemiological and clinical research: Confidence intervals for US RRs were created using bootstrap analyses with sample draws. Although the main clinical utility of hCG levels lies within early pregnancy, these findings underline the importance of hCG throughout gestational physiology and suggest that variations in hCG levels may be associated with adverse clinical outcomes. In order to compare the model cut-off values to the non-parametric cut-off values calculated per week2.

Reference ranges and determinants of total hCG levels during pregnancy: the Generation R Study
I agree to receive communication about exclusive promotions, offers and products from Huggies and other Kimberly-Clark brands. Since hCG is secreted by trophoblasts, the number of trophoblast cells approximated by the weight of the placenta may influence total hCG levels. Congratulations Take a look at each week of your pregnancy, from conception to birth, with our comprehensive email newsletters. Multiple imputation for missing data in epidemiological and clinical research: They are not definitive and are just meant to give an indication of what can be an average hCG range. In addition, we compared reference range determination by a sensitive model-based approach with the more conventional non-parametric approach and studied if total hCG RRs determined in the general population are different from RRs calculated in uncomplicated pregnancies only.
