Graph showing transient neutropenia in one patient during hemodialysis

Sequential changes in the total neutrophil and band count in a patient after the onset of hemodialysis with a cuprophan membrane. There is a dramatic and rapid fall in the total neutrophil count (solid line) that reaches a nadir at 15 minutes and then gradually returns toward baseline. The initial phase of the recovery is due in part to a marked increase in the number of immature band forms (dashed line).
