World Blood Donor Day- Celebrating 20 years of giving: Thank you, Blood Donors

Blood donation is a voluntary act that has the potential to save lives. Donated blood is used in various medical treatments, including surgeries, cancer treatments, chronic illnesses, and traumatic injuries. A single donation can provide vital components such as red cells, plasma, and platelets, benefiting multiple patients. 

Importance of blood donation:

A study published in the Global Journal of Transfusion Medicine by Bukar et al. (2020) highlights the inconspicuous health benefits of blood donation.  

  • Donating blood at least once a year reduces heart risks to the donor by improving blood flow and reducing blocked arteries. 
  • It balances the donor iron levels as too much iron in the blood can cause the arteries to harden and increase the risk of cancer. 
  • Donors receive a mini checkup, such as PCV, HIV, Hepatitis B & C, cholesterol, blood pressure, syphilis etc. This can sometimes help detect underlying health issues.  

Most importantly, it saves lives. 

Most people think blood donation is painful, can make you weak and you can even catch an infection from the process. However, it is important to debunk these myths as most of them are untrue.  Most donors feel only a slight pinch when the needle is inserted, but the entire process is painless.  

After donating blood, you may feel a bit weak and dizzy but that doesn’t last too long. Resting and staying hydrated, can help mitigate any temporary feelings of lightheadedness. Sterile, single-use needles and equipment are used to ensure that donating blood is safe and free from the risk of infection.

Blood Donation Process  

Donating blood is a simple yet impactful way to contribute to the health and well-being of others. The entire process is safe, typically taking about an hour from start to finish. Here’s a detailed breakdown of what to expect during a blood donation. 

  • Firstly, your blood is screened to identify your blood type, PCV and iron levels and any form of infection or diseases. 
  • If approved, you are required to take a lot of water before donation as this supports your overall bodily functions, ensuring you are in the best possible condition for donating blood. 
  • You will be asked to sit comfortably in a reclining chair. 
  • The skin on your arm will be cleaned with an antiseptic to prevent infection and a sterile needle will be inserted into a vein in your arm. This may cause a brief pinch. 
  • Blood is collected into a sterile bag. The process usually takes about 10 minutes. During this time, you can relax and read or listen to music. You will be monitored to ensure you are comfortable and the donation is proceeding smoothly. 
  • Once the bag is full, the needle will be removed, you may also feel a slight discomfort and a bandage will be applied to the site. 
  • You will be asked to remain seated for a few minutes to ensure you feel well. Rest for at least 15 minutes before leaving and continue to drink plenty of fluids and eat healthy meals. 
  • Avoid heavy lifting or vigorous exercise for the rest of the day avoid using the donation arm for heavy activities. 
  • If you feel lightheaded or unwell after leaving, lie down with your feet elevated until you feel better. 

Blood donation is a simple, safe, and vital act of generosity that can make a profound difference in the lives of others. By sharing the process, dispelling myths, and recognizing the importance of donating, we at Chayim Diagnostics encourage more people to participate in this life-saving practice.
