Hello everyone, I just passed the SBB this morning! Such a relief! I was kind of surprised by the type of questions. I am a relatively new tech with 3 yrs BB experience. I didn't go through a traditional program, just studied the TM as well as notes given to me from the Gulf coast last chance review. I will highly recommend these notes as there were several questions right out of here (4-5)! On my exam, I had (3) hardy questions, 5-6 coags(vWD and treatment), 2-3 % yield, several genetics on Lu, Le, En inheritance. Overall, I had less on rare blood groups than I thought, maybe 1 or 2 questions total. Hope this helps anyone.
