What is the Blood Donation Process?
Blood donation is a safe procedure and an easy process. All our blood bank staff observe strict hygiene protocols. The equipment used in blood collection (e.g., needles, swabs, gauze, tubing, etc.) are new, sterile, and discarded after one use. It takes about 45 minutes for whole blood donation and up to 90 minutes for apheresis donation. Read on to find out more about the donation process
1) Registration Your personal particulars will be recorded, and you will be asked to fill out a health assessment questionnaire.
2) Blood test Your blood haemoglobin level will be checked to ensure that you can donate.
3) Medical screening A health screener will ask you about your medical, travel and social history to confirm that you are fit to donate, after which your weight, blood pressure, pulse and body temperature will be taken.
4) Blood donation Your arm will be cleaned, after which a local painkiller will be applied to ensure that you feel minimal pain during the donation. The actual withdrawal of blood takes about 5 to 10 minutes, and about 350 – 450 ml of blood is collected.
