Obsessed with Helping You Learn Blood Banking

Let’s Be Honest…

Learning blood banking/transfusion medicine is scary! When you get started, you are overwhelmed by facts, regulations, and intimidating abbreviations like “FDA” and “AABB.” It’s easy to feel like you are in over your head.

I’ve been right where you are, and found my way out. Since then, I’ve helped guide learners just like you through the intimidating stuff toward mastery of this field. My name is Joe Chaffin, and I’m a transfusion medicine physician and teacher. For over 20 years, I’ve taught blood banking essentials to tens of thousands all around the world. I would love to help you, too!

Is This Site For You?

I started BBGuy.org in 1998 primarily to teach pathology residents. Today, the site exists to help anyone who wants to learn the essentials of blood banking and transfusion medicine. My teaching includes humor, occasional irreverence, and clear communication to highlight your path to understanding complex topics.

Blood Bank Guy?

Long ago, I would overhear attendees at my lectures say things like, “What time does the blood bank guy start lecturing?” or “Who is the blood bank guy again?” In fact, many years ago, while riding in a hotel elevator, I heard one lecture attendee who did not realize I was with her ask a fellow attendee, “Why the heck are we going down to listen to the *%$#*! blood bank guy?” It just made sense to christen my new site “Blood Bank Guy.”

Dr. Chaffin’s guidance is one of the primary reasons that I pursued a career in transfusion medicine. His systematic approach to education as well as his easily digestible and animated presentations made learning the basics of blood banking an enjoyable and pain-free process.

Before training with Dr. Chaffin, I could ‘get by’ memorizing answers; however, after spending time with him, I actually understood why those answers were correct. I walked out of my CP board exam knowing I aced the transfusion medicine portion and I credit Dr. Chaffin for this 100%!

As a practicing blood banker, I still rely on the various learning resources Joe provides and listen to his online lectures. I can’t think of anywhere else you can learn the basics but also keep up on the latest developments in the field.

Today I passed my ASCP SBB exam, with no small help from your website. From your notes to your podcasts, it has all been incredibly useful. No doubt I could not have done it without this wonderful resource!

I so appreciate your web site. Your sense of humor and teaching style beats any conference I’ve ever been to! I tell all of my fellow blood bankers about you! Please continue to provide this awesome service!
