Is collecting plasma harmful to health?

Will collecting plasma from patients cured in convalescence affect their health? First of all, as long as the patient recovers and reaches the discharge isolation standard, plasma can be collected. Plasma collection is a way of single plasma collection. Plasma is removed and red blood cells, white blood cells and platelets are returned. After 200 to 300 ml of this plasma is collected, the patient's plasma will completely return to its original state within a week or two, with little harm to the body. Don't worry too much. Recovery plasma can treat severe and critical patients. It is hoped that all convalescent patients will actively contribute to the treatment of severe patients and reduce the mortality rate. What's the difference between collecting plasma and donating blood? First, the object is different. Only patients who have recovered from the infection of coronavirus can be used as blood donors. Only when such patients have comprehensive antibodies in their plasma can COVID-19 infection be effectively treated. Second, only collect plasma, not whole blood. Generally, blood donation takes whole blood, including red blood cells and platelets, which are stratified. In clinical use, either plasma, platelets or red blood cells are used, which is the way of component blood transfusion. Only plasma is needed this time, and the rest is returned to the patient. Third, in addition to routine testing, COVID-19 nucleic acid testing should also be done. Routine examination should be done, such as the detection of infectious diseases such as hepatitis B and hepatitis C, to avoid cross-infection of blood transfusion. At the same time, COVID-19 antibody should be tested by qualified units, and the higher the titer of comprehensive antibody, the better the therapeutic effect, which is different. Another is to make nucleic acid. To detect viral nucleic acid, it must be negative. Of course, all the cured patients are negative, but before donating blood, they should be tested to ensure that there is no COVID-19 infection before donating blood.
