Part 640 discusses quality control parameters for blood and various blood components. Note that these are minimum standards. Quality control testing from the blood supplier(s) should be obtained in order to determine platelet and cryoprecipitate therapeutic doses.
Segments are required for red cell containing components in order to facilitate compatibility testing.
Storage temperatures and transport temperatures are defined and specified in this section.
