Here is a question I received early in January from Elpidio Pena. I apologize to Elpidio for letting this one slip through the cracks.
George: our lab performs the ristocetin cofactor (VWF activity) assay using the traditional platelet aggregation method. We are planning to change instruments and one of the instruments we are considering performs the assay by ELISA (coated beads). Any advantages/disadvantages on the ELISA method? Any particular issue to consider with this method?
Thank you, Elpidio. You don’t identify the instrument you are considering, however Instrumentation Laboratory (IL) is promoting their latex assay, which has accumulated some favorable data from several sources. Do any of our subscribers have experience to share?
