ID:905 ADAMTS13 Assay
Search Links: General Info : Protocols : LabTestsOnline

DescriptionADAMTS13 cleaves Von Willebrands factor into smaller multimers. A deficiency of inhibition of ADAMTS13 activity leads to very large Von Willebrands multimers being released into the circulation. These activate platelets causing aggregation and the formation of micro-thrombi. The poor prognosis associated with TTP requires early, accurate diagnosis
