ASCP BB · Put your knowledge to work in context.
The ASCP Board of Certification (BOC) Technologist in Blood Banking credential - usually written BB(ASCP) - is a professional certification for laboratory professionals who perform immunohematology testing and transfusion service work. It is intended for technologists who already have a generalist laboratory background and want formal recognition of specialized competence in blood banking, typically people working in hospital transfusion services, donor collection centers, or reference laboratories. The ASCP BB case studies are 5 cases and about 3,295 words.
