How Does Blood Donation Work?
Blood donation is a structured process. The blood service first checks whether you can donate safely, then collects the donation using sterile equipment and provides brief post-donation care.
Medical information notice: This article provides general educational information and does not determine whether you are medically eligible to donate blood. Final donor eligibility is assessed by the blood centre or qualified medical staff.
1. Registration and health questions
You provide your details and answer questions about your health, lifestyle and other factors relevant to donor selection. e-RaktKosh describes this pre-donation information as confidential.
2. Pre-donation screening
A blood-centre employee performs a short health assessment. Depending on the service, this can include checks such as pulse, temperature, blood pressure and a haemoglobin-related test.
3. Blood collection
If you are accepted as a donor, a trained health worker cleans the donation site and uses a sterile needle and blood collection bag. WHO says the actual donation commonly takes about 10 minutes, although the total visit is longer.
4. Rest and refreshments
After donation, you normally rest for a short period and have refreshments before leaving. The blood service can give you instructions specific to your situation.
5. What happens to the donation?
Donated blood is screened before it is released for use. Blood can also be processed into components such as red cells, platelets and plasma, allowing different components to serve different clinical needs.
