World Blood Donor Day: The Journey of Your Blood After Donation

Discover the meticulous process your blood undergoes after donation, ensuring safe and life-saving transfusions.
Every time someone donates blood, it sets off a highly coordinated and medically regulated process designed to ensure the safety of both the donor and the recipient. For World Blood Donor Day, observed annually on June 14, we explored the blood donation process in detail with Dr. Rachana Shamrao Pawar, in charge of the Blood Centre at K J Somaiya Hospital and Research Centre. This journey is governed by strict guidelines to maintain quality, sterility, and life-saving compatibility, far more complex than most people realize.
Step 1: Donor Selection Process
The donor selection process is the first and most crucial step. It involves a thorough physical examination and a deep dive into your medical history, conducted by qualified medical professionals. Governed by the Drugs and Cosmetics Act, this pre-donation process ensures that only healthy, eligible donors can give blood, safeguarding both the donor's well-being and the quality of the blood.
Step 2: Safe and Sterile Blood Collection
Once deemed eligible, blood is collected in a sterile, single-use bag by trained professionals who ensure complete sterility and donor comfort.
Step 3: Laboratory Testing and Disease Screening
The blood is grouped into its ABO and Rh type. Then, it undergoes Transfusion Transmitted Disease testing (TTD), screening for malaria, syphilis, hepatitis B and C, and HIV. These tests are essential to prevent infection transmission during transfusion.
Step 4: Crossmatching and Compatibility Checks
This step involves testing the donor’s blood with the patient’s serum to check for any antigen-antibody reaction, ensuring compatibility.
Step 5: Emergency Use of O Negative Blood
In emergencies, O negative blood is the universal donor for red blood cells, used when crossmatching isn't possible in time.
After these steps, the blood is divided into components: red blood cells, plasma, and platelets. Each component is stored under controlled conditions, with red blood cells usable for up to 35-42 days, platelets for 5-7 days, and plasma frozen for up to a year. This allows multiple patients to benefit from a single donation.
Dr. Pawar emphasizes the importance of regular donations to replenish blood components, helping meet the constant need and saving countless lives. Donating blood is a selfless act that goes far beyond the brief pinch of the needle—it’s a chain of life you become part of. If eligible, consider donating blood; it might be the most impactful thing you do today.
