How Many Cells are in a Leukopak?

Leukopaks may contain 5 to 20 billion white blood cells, depending on the volume of blood processed from the donor. They may also contain plasma, some platelets, and very few red blood cells.

Leukopaks typically consist of approximately 50% T cells, 20% monocytes, 10% B cells, 10% natural killer cells, 3% granulocytes, and 3% hematocrit.
