BSH guidelines recommend that when the size of the FMH is >2mL, the volume should be rechecked using a different technology. The second technology used within NHSBT is Flow Cytometry (FC) for D positive red cells. An advantage of FC is that it is a reliable method for measuring large volumes of D positive red cells accurately. how is owners draw from an s corp taxed
