Diagnostic Approach as Localization
Diagnose VWD by localizing failed hemostatic function, not by reacting to one abnormal test
First-Line Testing
What VWF antigen, platelet-dependent activity, factor VIII, CBC, PT, and aPTT can and cannot tell you
Second-Line VWD Testing
How multimers, collagen binding, RIPA, FVIII binding, VWFpp, and genetics refine diagnosis
Interpreting VWF Labs Relationally
Why VWF results make sense only in relation to one another and to the bleeding phenotype
Interpreting Bleeding Assessment Tools
Use BATs to structure bleeding history without worshipping the score
Laboratory Pitfalls and Repeat Testing
Why VWF testing is shaped by timing, stress, pregnancy, inflammation, assay limits, and repeat testing
Diagnostic Test Atlas
Interpreting von Willebrand factor assays: a diagnostic reference guide
