The association between abnormal coagulation testing in preeclampsia, adverse pregnancy outcomes, and placental histopathology

Objective: We aimed to determine whether abnormal coagulation laboratory testing results in preeclampsia, are associated with adverse pregnancy outcomes and placental histopathology lesions. Methods: Demographic, labor, laboratory-testing, and placental histopathology reports of pregnancies complicated by preeclampsia were compared between those with and without abnormal coagulation profile (ACP). Results: Of 348 cases of preeclampsia 16.1% had ACP. There were no differences between the groups in GA at delivery, severe features, placental-abruption, SGA, composite adverse neonatal outcome and placental histopathology lesions. Conclusion: ACP in pregnancies complicated by preeclampsia was not associated with any of the studied outcomes. Our data question the usefulness of routine coagulation tests in the initial assessment of women presenting with preeclampsia.
