The activity of protein C and antithrombin were measured using chromogenic methods (Berichrom Protein C, Berichrom Antithrombin; Siemens, Marburg, Germany). Levels of free protein S were evaluated with turbidimetric assay (Innovance Free protein S; Siemens, Marburg, Germany). Factor VIII activity was analyzed by a coagulometric test (Siemens, Marburg, Germany). The homocysteine concentration was assessed with a chemiluminescent microparticle immunoassay.
Innovance free protein s

Prothrombin time [PT], activated partial thromboplastin time [aPTT], and fibrinogen were determined by routine laboratory assays (Siemens, Marburg, Germany). The activity of antithrombin and protein C were measured with chromogenic methods (Innovance Antithrombin, Berichrom Protein C; Siemens, Marburg, Germany). Free protein S and D-dimer were assessed by turbidimetric assay (Innovance Free protein S and Innovance D-dimer; Siemens, Marburg, Germany). Factor (F)VIII activity was analyzed by a coagulometric test (Siemens, Marburg, Germany), similarly to activated protein C (APC) resistance (ProCAcR Siemenes, Marburg, Germany).
Commercially available immunoenzymatic assays were used to determine vWF antigen (Asserachrom vWF:Ag, Diagnostica Stago, New York, USA) and ADAMTS-13 antigen and activity (Technozym ADAMTS13 antigen ELISA kit and Technozym ADAMTS13 activity kit; Technoclone, Vienna, Austria).

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
