[Laboratory medicine for blood transfusion and transplantation medicine].
We discussed the usefulness of routine technologies of laboratory medicine in blood transfusion and transplantation medicine. New parameters that can be measured by automated hematology analyzers have been clinically evaluated and proven to be useful so far. Based on our experience, detection systems for fragmented red cells (FRC), immature platelets (immature platelet function, IPF), and hematopoietic progenitor cells (HPC) are useful for the diagnosis of thrombotic microangiopathy, differential diagnosis of thrombocytopenia, and decision regarding the optimal timing to collect peripheral stem cells, respectively. Moreover, IPF were suggested to be an indicator of the platelet transfusion requirement. The establishment of non invasive assaying technology has been eagerly anticipated. We evaluated a hemoglobin measurement tool, and revealed that it might be applicable in predeposited, autologous blood donation. Some adverse transfusion reactions are related to neutrophil activation. Thus, we investigated the effects of serum from patients and blood donors, in the context of adverse reactions, on adhesion molecule expressions of neutrophils from volunteers using flow-cytometry. This kind of simple technology is expected to be useful in future studies to clarify the mechanisms and prevent adverse reactions.
