This will be a prospective study conducted on women with a suspected/confirmed diagnosis of placental abruption. Maternal blood samples will be taken at various points during the peripartum period. A healthy group of women admitted for delivery will act as a matched control and will have their blood sampled at similar time points. The primary outcome variables will include the total number of micro-particles, the number of micro-particles from each cell line (platelet, placental, endothelial etc.), and protein markers (specifically; placental growth factor (PlGF), soluble fms-like tyrosine kinase-1 (sFLT-1), vascular endothelial growth factor (VEGF), soluble endoglin (sEng)). Secondary outcomes if will examine the correlation between placental micro-particles, biomarkers, and extent of placental abruption.
