    von Willebrand Factor (VWF) is a pro-coagulant 
	protein which plays an important role in hemostasis. von Willebrand disease, 
	(vWD), the most common inherited bleeding disorder, is caused by either 
	quantitative (Type I) or qualitative (Type II) deficiency. Both quantitative 
	(antigenic) and qualitative (functional) assays are important in the 
	diagnosis and treatment of vWD.  
    
		- von Willebrand Factor Antigen ELISA is a quantitative test 
		for determining von Willebrand Factor Antigen levels in citrated human 
		plasma.
      	
 
		- von Willebrand Factor Activity Test is an ELISA for detecting 
		VWF activity in citrated human plasma. A purified monoclonal antibody 
		which recognizes a functional epitope on the vWF antigen is used to 
		measure vWF activity (function), rather than total vWF concentration. 
 
	 
    Protein C contributes to the maintenance of 
	normal hemostasis by limiting clot formation and promoting fibrinolysis. 
	Deficiency, either congenital or acquired, may lead to serious thrombotic 
	events.  
    Protein S serves as a cofactor for the 
	anticoagulant and fibrinolytic effects of activated protein C. Protein S 
	deficiency, either congenital or acquired, may lead to serious thrombotic 
	events. The measurement of both total and free Protein S (the functionally 
	active form) is useful in classifying patients with congenital Protein S 
	deficiency.   |
