However, severe thrombocytopenia may develop in pregnant women with preeclampsia and the HELLP syndrome (h emolysis, e levated l iver enzymes, and l ow p latelets); such women typically require immediate delivery, and platelet transfusion is considered if platelet count is < 20, 000 / mcL (20 × 10 9 / L), or < 50, 000 / mcL (< 50 × 10 9 / L) if delivery is to be cesarean.
