Thanks to all who attended our free webinar, Improving Acute Care with Coagulation Mixing Studies, Wednesday, May 13, sponsored by Precision BioLogic Inc. You can see and hear an archived copy of the entire webinar by registering on the Precision BioLogic web site by June 12. The webinar was hosted by CACMLE.
There was an interesting question at the end of the webinar that requires further discussion,. A participant asked if it was appropriate to use control plasmas as a part of the mixing study. Though it seems appropriate, it is not standard practice to include controls. For those who use controls, what is the nature of your control? Do you use an LA-positive control? A factor-deficient control? Or a plasma that contains a specific inhibitor such as anti-FVIII? Do you perform both an immediate and incubated mix on the control? Thank you in advance for your answer.
Another participant asked about the use of a saline mix, which led us to reprise a 2013 Mixing Study post by Courney Jackson.The 2013 post goes into detail on interpreting the salne mix.
