A reliable screening test for platelet function is_______________?
Correct answer: D. Clot retraction time
- A. CT
- B. PT
- C. Thrombin
- D. Clot retraction time
Explanation
Clot retraction depends largely on functioning and adequate numbers of platelets, so it can provide a rough assessment of platelet function. PT evaluates the extrinsic pathway, whereas thrombin time evaluates fibrin formation; bleeding time would be the classic screening test but is not listed.
