Blood Donation Process

Blood donation is a safe procedure and 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 and up to 90 minutes for apheresis donation. Read on to find out more about the donation process

You need one identity proof for registration, a contactable address and a telephone number in Singapore within the next 3 months. If you are below 18 years old, you will also need a signed parental consent form.


Dear Blood Donors,

Some of you go through most of the stations of the blood donation process only to find out that you are unable to donate due to low haemoglobin (Hb). We understand that this is not ideal for you and we have looked into this matter.

From 3 June 2019, the blood donation flow will be improved. You will go through Haemoglobin (Hb) testing before Medical Screening. This change will shorten the waiting time for donors with low Hb. You will find out earlier whether you meet the required Hb level. If your Hb level is low, you will not need to go through the Medical Screening station,  thus saving you time.

Should you have any questions, please approach any of our staff.

1) Registration
Your personal particulars will be recorded and you will be asked to fill out a health assessment questionnaire.



2) Blood test
Your weight and blood haemoglobin level will be checked to ensure that it is safe for you to donate blood.



3) Medical screening
Your blood pressure, pulse and temperature will be checked and your medical, travel and social history will be assessed to confirm that you are fit to donate blood.


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.
5) Refreshments
After the donation, you are advised to rest for 10 to 15 minutes and have some light refreshments before resuming normal activities. Here are some tips on Post-donation care.
