Preeclampsia is a serious medical condition found in approximately 5% of pregnant women. Although it is not usually fatal, it is characterized by hypertension, proteinuria, and edema. Complications can include seizures, stroke, and kidney and liver failure. Researchers have hypothesized that preeclampsia results from an imbalance of angiogenic factors and recent studies show that serum, plasma, and urine PlGF levels decrease significantly in women with preeclampsia and/or those who subsequently develop the disorder.

R&D Systems Quantikine® Human PlGF ELISA is now fully-validated for urine as well as serum, plasma, and cell culture supernate samples. This assay has a sensitivity of less than 7 pg/mL and a dynamic range of 15.6 to 1,000 pg/mL.
