Blood donation to know about
When a person volunteers to his or her blood to be drawn and offers it for transfusion to some other person (may be known or unknown). The whole process is medically termed as bio-pharmaceutical medications. Since the process involves fractionation that is whole-blood components’ separation, the donation may be of 2 types: - 1) apheresis or specific components through some direct way and 2) WB i.e. whole blood.
Who are involved in the blood donation procedure?
The entire procedure of blood collection and the next process of culturing it and implementing its transfusions are done by the blood banks.
What is the present scenario in this modern world?
In this modern world, the whole blood donation job is done voluntarily as a benevolent and philanthropic job for serving community. The blood donations has a peculiar scenario that is in the developed world blood donations are done as a voluntary job while in the poorer countries family members donate blood only when their nearer ones are in need of blood transfusions. However, in most of the cases the blood donations are considered as the act of charity. Some countries do allow the donors to be paid. The paid donors are also given incentives like paid-time-off from their service.
What is autologous donation?
When a blood donor donates his or her blood for his or her future needs, it is known as autologous donation.
How is the blood donation safe?
Blood donations are always safe, except some cases a donor may feel pain at the place of needle insertion; even some donors get fainted by seeing the blood being drawn from his or her own body.
Can any blood be always safe to be used?
No, every time blood being donated or drawn for some transfusion purpose is not safe. In most of the times blood is strictly screened for viral hepatitis or for HIV types of transmittable diseases.
Is the donor questioned for medical reason before donating blood?
Yes doctors feel it medically suitable to question the donor. The questions are mostly physical examination and family history. These are needed for both the donor’s and recipients’ wellbeing. The donor must not feel weakness and the recipient on the other hand must not fall sick by disease laced blood from a donor.
How often you can donate blood?
You can donate blood depending upon your days and months of earlier donations and the country law you are subjected to adhere to.
In USA, you cannot donate your whole blood before you wait for 56 days or 8 weeks after your last donation. But if you want to donate only “platelets autologous” you have to wait a single week or seven days.
Are the blood drawing process and the amount of blood being drawn the same in every case?
No, it varies depending upon the manual or automation methods being present or available at the time of drawing of blood. In case the automatic system is deployed, some specific portion of blood is taken away.
Self-life of the blood components:-
Most of the components in blood have a short self-life. So it must be noted that keeping the continuity of the supply of the components is always a problem. This is the reason auto transfusion is widely chosen in these days. The other notable point is a patient’s blood is continuously salvaged for reinfusion during surgeries. This factor also influences a donor to donate a “self-donated” blood for the future use. Of course, in this case the word “donation” does not get ethically accepted but it has become an idiomatically accepted term in the domain of medical ethics.
