Table. Results of Patient’s Diagnostic Evaluation

Variable	Results	Reference Range
Activated clotting time, seconds	424	70-150
Partial thromboplastin time, seconds	37.8	21.0-32.0
	50.2
	35.6
Prekallikrein activity, %	<5	63-135
High molecular weight kininogen activity, %	153	65-135

Note: Prolonged activated clotting time was noted immediately prior to the initial planned surgical procedure. Partial thromboplastin time, prekallikrein activity, and high molecular weight kininogen activity were determined at subsequent hematology visits.
