ASCP RECALLS COMPREHENSIVE STUDY
QUESTIONS AND ANSWERS
◉ Cryoprecipitate used for.
Answer: Replace fibrinogen loss due to DIC
Massive bleeding
Dysfibrinogenemia with active bleeding
◉ Plateletpheresis preparation steps.
Answer: Light spin (remove RBC)
Heavy spin (spin down PLT and WBC)
Supernatant goes into bag for freezing (FFP)
Remaining plasma, platelets, and WBC = platelets
◉ Irradiated blood prevents.
Answer: GVHD
,Also used for cancer patients, or patients who are
immunocompromised
◉ Leukocyte reduced blood prevents.
Answer: Febrile nonhemolytic transfusion reactions (FNHTRs)
◉ Blood generally kept at what temperature?.
Answer: 1-10C

Answer: 20-24C
Platelets usually kept on agitator to ensure that the platelets are
continuously oxygenated
