Technical Q&A

Technical FAQs and discussions from Dr. Chaffin and colleagues (Coming soon!).

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!
