What would be the expected laboratory results in a patient with thrombocytopenia?

Question

Quizplus · Accepted Answer

Thrombocytopenia refers to a low platelet count, and platelet counts less than 50 x 10^9/L are common in this condition.

Answer: B
 Bleeding time may be prolonged in thrombocytopenia, as platelets play a crucial role in the formation of a clot to stop bleeding.

Answer: C
 PT and APTT (prothrombin time and activated partial thromboplastin time) are tests that assess different clotting factors in the blood. In thrombocytopenia, the PT and APTT may be normal or only mildly prolonged, as platelets are not directly involved in these pathways.

Answer: D
 Fibrinogen is a clotting factor produced by the liver, and its levels can be decreased in conditions that affect clotting, such as thrombocytopenia. However, this is not a consistent finding and fibrinogen levels may be within the normal range in some patients with thrombocytopenia.
