Blood Products Availability

November 23, 2022

Blood Products Availability is published biweekly on the AABB Newsfeed and in Weekly Report. This estimate is based on data from AABB's National Blood Exchange and is intended to complement the weekly Group O blood supply report. 


The demand for platelets often rises sharply the week following Thanksgiving due to donor travel. However, current availability of platelets is strong, and demand is moderate.

Red Blood Cells

A-positive and B-positive RBCs are plentiful. However, meeting all needs can take up to a week in portions of the Northeast, Southeast and Southwestern U.S due to high usage of type O and Rh-negative RBCs. This growing trend in usage may last through the holiday season into spring.  

Frozen Products

Type O plasma is readily available, but at least four days are needed to address ongoing usage for types A and B plasma. Several weeks are needed to locate single-digit quantities of AB plasma due to long-standing, limited availability. There is increasing use of single cryoprecipitate, and national availability is robust. Quantities of pooled cryoprecipitate continue to build throughout the country.

Seasonal Reminder

AABB's team of industry-trained professionals can help when inventory levels are seasonally low. AABB's National Blood Exchange is a partner benefit for all AABB institutional members in good standing.
