A: Because donating blood as a healthy adult (18 to 55 years old) is a good thing for others and self-interest, most areas of medical blood are now completely ** unpaid blood donation. Blood is an important substance that saves the lives of injured and sick people, and it has not been artificially produced until now, and can only be provided by people with love.

Donation of blood components, as the name suggests, is a component of the blood. The most common component of blood donation today is platelet donation. As we all know, human blood is composed of red blood cells, white blood cells, platelets, plasma and other components.

Component transfusion is a new concept in modern blood transfusion. It is very unreasonable to give a traditional blood transfusion** to whole blood regardless of the patient's needs. Practice has proved that about 80% of patients with blood transfusions are not lacking whole blood, but only a certain component of the blood.

The component blood can be transfused to the corresponding component according to the needs of the patient, so as to achieve the purpose of making up for what is lacking, greatly improve the efficacy, save blood source, and reduce the adverse reactions caused by the input of unnecessary components.
