The diagnostic accuracy of PlGF (at the prespecified threshold of <100 pg/mL) in predicting preeclampsia requiring delivery within 14 days (or <37 weeks’ gestation in those recruited at 35+0 to 36+6 weeks’ gestation) for the repeat PlGF test was high: sensitivity 90.7% (95% CI 82.5‐95.9), negative predictive value 92.2% (95% CI 85.3‐96.6) and, similar to that of the first PlGF test in this cohort: sensitivity 87.5% (95% CI 67.6‐97.3), negative predictive value 97.7% (95% CI 93.5‐99.5). The gene discussed is PGF; the disease is preeclampsia.
