The hazards of plasma collection

When we have a physical examination in the hospital or donate blood, our blood will be drawn. With the development of medical technology, we can now collect plasma alone. Everyone knows about blood drawing, but they don't know what it means to collect plasma alone. The so-called single plasma collection refers to the process of separating the human blood through equipment during blood collection, separating the components of the plasma, and at the same time transfusing the red blood cells to the blood collector.

The dangers of plasma collection

Under normal circumstances, single-donor plasma is harmless to the human body and has certain benefits. However, the operation of current single-donor plasma stations needs to be improved and standardized. Although the state has strengthened the management of single-donor plasma stations, and the plasma stations appear to comply with national regulations, they will some extent violate regulations for the sake of profit, increasing the chance of harm to the human body. It is recommended to inspect the plasma station before collecting plasma and communicate with other people who have donated plasma.

The procedure of plasmapheresis:

1 The blood donor arrives at the plasma collection station, and after passing the physical examination and laboratory tests, blood is collected, plasma is separated, and the red blood cells are returned to the blood donor.

2 The amount of whole blood collected for each process should not exceed 600ml (excluding anticoagulants). For double-pass plasma collection, the second pass should be performed after the red blood cells collected in the first pass have been returned to the blood donor.

3 Blood collection must use a sterile closed system and be performed in a clean environment in strict accordance with sterile procedures.

4 During the blood collection process, the anticoagulant should be mixed with the whole blood in time, and the blood should be free of clots.

5 During the plasmapheresis process, all equipment used, such as syringes and blood transfusion equipment, should be disposable and destroyed after use.

The difference between donating blood and donating plasma

Blood is composed of 55% to 60% plasma and 40% to 45% blood cells (red blood cells, white blood cells, and platelets).

Blood donation is to extract the whole blood of the donor. Plasma donation is to use a fully automatic plasma collection machine to separate the plasma part of the human blood through a centrifuge, and then return the red blood cells, white blood cells, platelets, etc. to the donor so that he can quickly recover his physical strength.
