This is an interesting issue that we have encountered in our laboratory too. We have used a Kaolin based reagent with good success in some cases. I will be giving an oral presentation at the upcoming Mayo Testing Quality Conference about our experience using an alternative
activating reagent to perform factor assays in the presence of Lupus Anticoagulants.
