On June 28, hemostasis researcher Dave McGlasson asked George, "what temperatures do most of us use to store centrifuged, platelet-poor plasma when testing is delayed?" We assumed most of us use –70ºC freezers, but it may be that many lab practitioners use alternative specimen storage protocols.

Dr. Ali Sadeghi-Khomami, Precision BioLogic Inc., provided these in-depth technical questions about the Nijmegen Bethesda Assay (NBA), which we use to quantitate specific factor inhibitors such as anti-factor VIII or anti-factor IX. George forwarded his questions to Connie Miller and Amanda Payne, US Centers for Disease Control and Prevention (CDC ) who have been working on NBA accuracy and precision upgrades for several years. Here are Dr. Ali's questions and answers provided by Drs. Miller and Payne; thanks to all for your support.
