Clinical Medical Assistant Exam Practice Question
What could be a potential consequence of not allowing a serum tube to clot long enough before centrifugation?
Correct Answer: B
Rationale: Allowing a serum tube to clot adequately before centrifugation is crucial for accurate test results. Incomplete clotting (Option B) can lead to serum that contains fibrinogen and other clotting factors, which may interfere with various tests, yielding misleading results.
Option A, hemolysis, typically results from improper handling or excessive force during centrifugation, not directly from clotting time. Option C, hemoconcentration, occurs when blood components become concentrated, often due to dehydration or prolonged tourniquet use, not from clotting issues. Option D, no impact, is incorrect as inadequate clotting can significantly affect test accuracy.
