When do you often see spherocytes?
DIC (disseminated intravascular coagulopathy), IMHA (immune mediated hemolytic anemia)
What is DIC?
Disseminated Intravascular Coagulopathy
What is IMHA?
Immune mediated hemolytic anemia
What is a diagnosis of IMHA?
Agglutination
What causes crenation?
Can be created by placing RBC’s in hypertonic solution OR by drying a blood smear to rapidly. Change in pH and longer contact with EDTA
