Gestational thrombocytopenia is defined by a platelet count below which threshold?

Gestational thrombocytopenia is defined by a platelet count below which threshold?

• A. 100,000 per microliter
• B. 150,000 per microliter
• C. 200,000 per microliter
• D. 50,000 per microliter

Answer: (B)

Gestational thrombocytopenia is a mild, pregnancy-associated decrease in platelets that is common and typically benign. It is defined by a platelet count below 150,000 per microliter. Platelet counts in this range are associated with little to no bleeding risk and often require only routine monitoring. Normal platelet counts are about 150,000 to 400,000 per microliter, so values below 150,000 fit the definition of thrombocytopenia in pregnancy. Very low counts (for example, well under 100,000) raise concern for other conditions such as immune thrombocytopenia, HELLP syndrome, or DIC and warrant further evaluation. In gestational thrombocytopenia, most cases occur in the third trimester and tend to resolve after delivery, requiring no special treatment beyond observation.
