Platelet apheresis concentrates are an invaluable blood product in the treatment of many disorders involving platelet deficiency. Congenital diseases such as Glanzmann’s thrombasthenia, Platelet type von Willebrand disease, and May-Heggelin anomaly, as well as acquired diseases such as Dengue Hemorrhagic Fever rely on platelet transfusions.

A previous article focused on the testing of platelet concentrates as they are stored in the laboratory facility. A study by Horvath, et.al., however, tested the patient’s blood for platelet function after a platelet transfusion has been done. In many cases, the effect of a platelet transfusion is quantified as an increase in the platelet count and not the platelet function.

The use of Impact-R as a diagnostic and monitoring tool for platelet function is feasible as was concluded by Horvath, et.al.
