Osler Blood Bank Lecture 2014

If you are thinking of attending the Osler Institute Pathology Review Course and are wondering whether or not I will be giving the blood bank lectures, this page will give you a bit of information about my schedule for 2014.

The Osler Institute has announced the schedule for their last Pathology Review course in 2014. I plan to be present to deliver the blood bank review lecture at the October 12-18, 2014 course in Tampa, FL.

If you are interested, you can download the notes from the Spring 2014 course (Los Angeles, March 2014).

Please believe me when I tell you that I'm not arrogant enough to believe that any of you are sitting at home saying, "If that Chaffin guy ain't talking, I ain't going!", but I just wanted to give you fair warning of when I will and won't be at the individual courses, in case you care! Check back here for updates. Thank you for your understanding.
