CPT (Certified Phlebotomy Technician) Practice Exam

The purpose of a blood bank collection is primarily to gather blood for transfusions and storage. This process is crucial as it ensures that there is a sufficient supply of blood available for patients who need it during surgeries, medical emergencies, or for individuals with certain medical conditions that require blood transfusions. The collected blood is stored in various components, such as red blood cells, platelets, and plasma, each serving different medical needs. This careful collection and storage enable healthcare facilities to provide timely and safe blood transfusions to patients.

The other options, while they involve important aspects of blood handling and testing, do not capture the primary function of a blood bank collection. Testing for blood diseases is an essential practice, but it is part of the overall management of blood safety and quality rather than the collection process itself. Similarly, maintaining a complete blood count is a laboratory process that requires testing samples, but it does not pertain directly to the collection of blood for a blood bank. Finally, donating blood to research facilities could be part of specific blood donation programs, but it is not the main purpose of a blood bank collection, which focuses on transfusion readiness and patient care.
