Bleeding time and clotting time during pregnancy are unchanged. Which option best reflects this?

• A. Increased
• B. Decreased
• C. Unchanged
• D. Erratic

Answer: (C)

Pregnancy shifts the body toward a hypercoagulable state to protect against postpartum bleeding. Coagulation factors and fibrinogen rise, von Willebrand factor increases, and platelets may be more activated, promoting quicker clot formation in vivo. However, bleeding time (which reflects platelet plug formation in vivo) and clotting time (a basic in vitro measure of clot formation) typically stay within normal limits in uncomplicated pregnancies. The procoagulant changes affect overall clot risk rather than these traditional time-based tests, so the best reflection is that these times are unchanged. In conditions like thrombocytopenia or von Willebrand disease, bleeding time can be prolonged, but in a healthy pregnancy they remain normal.
