AABB has issued a technical correction to the Circular of Information for the Use of Human Blood and Blood Components (August 2009) (hereinafter referred to as the Circular of Information 2009 or the 2009 version). With respect to the dosage and administration of platelet components (pages 40 and 41 of the printed brochure and pages 20 and 21 of the electronic file), the reported units for the corrected count increment (CCI) should be per mL per 10¹¹ per m². The 2002 version of the Circular of Information did not include units; however, the 2009 version includes the units “/mL.” A Letter to the Editor published in the journal Transfusion [1993;33:358-9] explores the units of the corrected count increment and provides the rationale for the use of “per mL per 10¹¹ per m².”

In order to ensure that the Circular of Information 2009 is consistent with the journal, AABB is issuing the following instructions for correcting the 2009 version.
