Low first-trimester serum concentrations of hyperglycosylated human chorionic gonadotrophin (hCG-h) predict later preeclampsia. We studied whether serum hCG-h at 14–17 weeks of pregnancy also predicts preeclampsia alone or combined with placental growth factor (PlGF) and soluble vascular endothelial growth factor 1 (sVEGFR-1).


We conducted a nested case–control study comprising 55 women with subsequent preeclampsia, 21 with gestational hypertension, 30 with a small-for-gestational-age infant, and 83 controls. Serum concentrations of hCG-h, proportion of hCG-h to hCG (%hCG-h), PlGF, and sVEGFR-1 were converted to multiples of the medians (MoMs) adjusted for gestational age.


Concentrations of hCG-h or %hCG-h did not differ between women with subsequent preeclampsia and controls. In women with subsequent preeclampsia, PlGF was lower (0.62 MoM) than in controls (P < 0.001). In receiver-operating characteristics curve analysis for the prediction of preeclampsia, the area under the curve for hCG-h or %hCG-h was not significantly different from 0.5, whereas that for PlGF was 0.746 (95% confidence interval, 0.656–0.836; P < 0.001). Combining hCG-h or %hCG-h with PlGF did not improve the prognostic value.
