You walk in just as the transfusion is about to begin and see that the nurse is about to spike the unit with a standard IV infusion set connected directly to her left arm. You say: No problem" "This product must be infused through a microaggregate filter" "This product must be infused through a standard blood filter" "This product must be infused through a leukocyte reduction filter" "This product must be washed before it is infused

"This product must be infused through a standard blood filter"

A "microaggregate" blood filter has an approximate filter screen size of: 170 microns 40 microns 15 microns 8 microns 2 microns
