Answer

Multimeric examination of vWF is particularly important in the diagnosis of vWD type 2. Results from this laboratory test reveal the multimeric distribution of vWF, thus allowing classification of type 2 disease based on the specific absence of large multimers (type 2B) or both intermediate and large (type 2A) multimers.
