Each blood donation is important and saves lives. You can also make a difference; just dare to overcome your reticence.
Blood is a biological fluid essential to life, made up of several elements and substances, including water, red blood cells, white blood cells, and platelets. It performs a number of functions, including:
Unfortunately, researchers have not yet succeeded in creating artificial blood that could completely replace the blood of an injured or sick person, hence the importance of blood donation.
Blood also has specificities that make blood transfusions a little more complicated. There are four blood types: O, A, B and AB. The rhesus (Rh) factor determines whether the blood type is positive (+) or negative (-). The O+ blood type is found in the largest proportion of the population (39%), while the AB- blood type is found in only 0.5% of people.
Before transfusing blood to a person, it is necessary to ensure that the donor's blood is compatible with the recipient's blood. Otherwise, an immune reaction could occur: the transfused blood may be perceived as a foreign substance, which could lead to rejection and a deterioration of the health of the person receiving the transfusion.
The diversity of blood types makes it important to use donors of all groups in order to facilitate blood transfusions and to have a sufficient blood supply to meet all hospital demands.
When blood is donated, care is provided by healthcare professionals (most often nurses) and volunteers throughout the process.
The amount of blood drawn is only one-twelfth of the total amount of blood flowing through your body. This means your body will have no trouble regenerating the blood that was donated. In less than 24 hours, the plasma is completely replenished, while after about 8 weeks, all the blood components are renewed. Every eight weeks, a person can donate blood without harming their health.
Donating blood, if not done under optimal conditions, can carry some risks, including the transmission of certain diseases (e.g., HIV, hepatitis B or C infection). The Héma-Québec team works to protect both donors and recipients by ensuring that the blood collected is free of any diseases and is safe for transfusion. If a condition deemed risky is detected, blood donation will not be permitted. Additionally, a questionnaire is done on site and several laboratory tests are performed on each blood bag collected to eliminate any risk of contamination. You can visit Héma-Québec's website to learn more, and the nursing staff on site will be able to provide you with information.
Here are a few conditions to be able to give blood:
A person may need a blood transfusion for several reasons, such as cancer, a car accident or another illness. In Quebec, more than 1,000 transfusions must be performed every day to save lives. This shows that donating blood is valuable and that it is important that hundreds of people decide to become donors.
