Amazing Facts About Blood Collection and Process
By the way, there is very little blood donation in the world, but if there is a tragedy and a call for blood donation is made, there is a line of thousands of people outside the blood banks to donate blood. Many of you have donated blood at some point. But do you know? what happens to your donated blood after donating blood? Do you think? that the person for whom you have come to donate blood will be given the same blood that you gave a while ago? So the simple answer is NO. So let us tell you what happens to the blood you donate after donating blood.
Does Donating Blood Make You Weak?
Let me dispel some of your misconceptions that people who think that giving blood will weaken them or make them sick are not right.
When the blood donor is ready to donate blood, he is tested to see if he has anemia or if he will become weak after donating blood. And when it is ensured that there is no danger to the life of the donor, blood is taken from him, and not only that, blood donors also test for malaria, hepatitis, and HIV before taking blood. To ensure that blood is taken from a healthy person.
How Much Blood You Donate:
Did you know that a blood bag has a capacity of 400 ml? Fifty milliliters of which is the only liquid that does not allow blood to coagulate, which is called ant coagulant, which means that you donate blood up to 350 milliliters after donating blood. Did you know that How much blood is in a healthy body? About 5,000 ml means five liters, 350 ml of blood, you can make it in a week or two, but you have to wait for another blood transfusion, about 12 to 16 weeks, about 12 weeks for men and about 16 weeks for women.
No one is transfused immediately after the blood is drawn, but the blood is re-checked or scanned, which includes hepatitis C and B tests, Malaria tests are required, and many other diseases are tested. Which may be due to blood transfusions and also blood grouping is done to find out which group the blood belongs to so that the patient can be tested according to this calculation. When the blood enters the bank, the blood bag is placed in a machine and centrifuged, which divides the blood into three parts.
Components of Blood:
There are three components of Blood (red blood cells, platelets, plasma) from blood these three components are separated and kept separated. Usually, when the doctor says that the patient needs blood, it usually means that he needs RBCs. RBCs are needed during surgery, at the time of childbirth, or usually in anemic conditions RBCs needed in excessive amounts.
And the platelets are kept for another patient who may be suffering from cancer. Platelets help the blood to clot. For example, if you are injured and start bleeding, These are the platelets that go to the site and fill the area to stop the blood from flowing, which stops the flow of what happens. Cancer patients and HIV patients usually need platelets.
The third part, plasma, usually contains water, contains salts, contains antibodies, and enzymes. But there is a very important thing in plasma and they are antibodies and proteins. You must have never seen a movie in a zombie movie that shows that the hero’s daughter is the only girl. a zombie who can’t eat because his blood is different from other human beings, so there that is not his blood but his plasma.It is said that her plasma is different from other people. This girl’s plasma has such antibodies that even if a zombie bites it, it does not become a zombie. Once these components of blood are separated. they are preserved and each ingredient has an expiration date and varies from country to country, but platelets usually last up to five days, RBCs up to 28 days, and plasma one year. It lasts for a year. Another important thing here is that after 28 days, the blood does not deteriorate, but it is not suitable for transplantation. This means that if someone receives a blood transfusion that is 20 days old or 28 days old, it will be correct because RBCs are usually up to 90 days old. That’s why in the United States, even 35-day-old blood is used, so RBCs and platelets are usually used in the area where they come from because they don’t have much time to make a country. To be taken to another country.
But plasma is shipped all over the world where it is needed. Another interesting thing is that when you go to donate blood to someone, the blood bank stores your blood, and which is about twenty to twenty-five days old that is transfused. And as I said before it is very normal and very good work because the shelf life of biological fluids is a very important challenge. Blood Bank always tries to be in touch with other banks Because they send their expired blood to another blood bank in advance so that they can use it. Technically, blood taken from one person may be of use to three or four people.
Another thing is that when someone needs blood, then the person is not given the same blood group? Blood is transfused only when the two bloods do not show any reaction to each other.
