II. Epidemiology
- Most common cause of Thrombocytopenia in pregnancy
- Incidence: 8% of pregnant women
III. Pathophysiology
- Increased Platelet clearance
- Hemodilution
IV. Labs
V. Evaluation
- No additional evaluation required if
- Platelet Count >115,000 per uL and
- No signs of Preeclampsia or HELLP Syndrome
- Discuss lower Platelet Counts with hematology or maternal fetal medicine
- Obtain Platelet Count in newborns if maternal Immune Thrombocytopenic Purpura is suspected
VI. Differential Diagnosis
- See Thrombocytopenia
- Preeclampsia with HELLP Syndrome
- Immune Throbocytopenic Purpura
VII. Course
- Resolves spontaenously after delivery
VIII. Prognosis
- Benign condition with no associated increased morbidity or mortality in pregnant women or newborns
