Due to the ongoing COVID-19 pandemic, AABB has elected to delay the effective dates of the 32nd edition of Standards for Blood Banks and Transfusion Services (BBTS) and 11th edition of Standards for Immunohematology Reference Laboratories (IRL) to July 1, 2020. AABB previously scheduled both sets of Standards to take effect on April 1, 2020. AABB reserves the right to extend the effective dates past July 1, 2020, if deemed appropriate.
At this time, AABB expects each set of Standards to remain in effect for 21 months, with the next editions of each set of Standards taking effect April 1, 2022. To prepare for the July 1, 2020, effective dates, individuals can access the Standards Committee's responses to comments and significant changes online. Those with questions should contact AABB's Standards department at firstname.lastname@example.org.
