which of the following marker is used primarily to diagnose bleeding disorders?
fibrinogen
homocysteine
prothrombin time
activated partial thromboplastin time

Explanation:

• Fibrinogen is a protein involved in clot formation but not primarily for diagnosing bleeding disorders.
• Homocysteine is related to cardiovascular and neurological issues, not bleeding disorders.
• Prothrombin time (PT) measures the extrinsic pathway of coagulation and is used to monitor warfarin therapy and assess liver function in part, but activated partial thromboplastin time (aPTT) is more specific for bleeding disorders as it measures the intrinsic pathway.
• Activated partial thromboplastin time (aPTT) is used to diagnose bleeding disorders as it assesses the intrinsic and common pathways of coagulation.

Answer:

activated partial thromboplastin time
