Platelet counts are essential in transfusion practice because they help determine the need for platelet transfusions. In patients with low platelet counts, or thrombocytopenia, there is an increased risk of bleeding, and monitoring these counts allows healthcare providers to decide when a transfusion is necessary to restore adequate platelet levels.

A low platelet count can indicate the need for transfusion before, during, or after surgical procedures or in the management of conditions that affect platelet production, such as certain cancers or bone marrow disorders. By assessing the patient's platelet levels, clinicians can make informed decisions about treatment and improve outcomes for those at risk of bleeding complications.

Other options, such as increasing blood clotting time, indicating the risk of infection, or determining donor compatibility, do not reflect the primary role of platelet counts in transfusion practice, which is focused on managing and preventing bleeding through appropriate transfusion interventions.
