Clinical Info |
Reflexive algorithm always includes: FVIII Activity, VWF Antigen, VWF:GPIbM Activity, and VWF Collagen III Binding. Reflex testing may include: VWF Quantitative Multimer, VWF Propeptide Antigen, VWD Type 2N Binding and/or VWD Type 2B Binding. For patients <6 months of age, the ELISA-based VWF GPIbM Activity will be performed. For patients >/=6 months of age, Turbidimetric latex-based assay VWF GPIbM Binding Activity will be performed. VWF GPIbM Activity methodology cannot be changed upon request. USA test status for ELISA method: This is a laboratory developed test (LDT). USA test status for Turbidimetric latex-based method: This is an In Vitro Diagnostic test (IVD). |
