What Does PTR Stand For?

PTR stands for Platelet Transfusion Reaction

Platelet Transfusion Reaction (PTR) refers to an adverse response that occurs following the transfusion of platelet components into a patient. Symptoms may include fever, chills, hypotension, and respiratory distress, often resulting from immune-mediated mechanisms or allergic reactions. Effective management includes prompt recognition, supportive care, and, when necessary, further investigation to prevent recurrence in future transfusions.
