Before making an appointment to donate, it is important to be aware of some of the common reasons that could lead to a deferral or unsuccessful donation, and of how donating blood could affect your ability to carry out some activities later.
When Not To Donate In general, if you're currently undergoing treatment for a major illness or surgery, or (for women) if you're pregnant or experiencing heavy menstrual flow, you're advised to delay your blood donation for the time being.
For donors who have recently travelled overseas, there are also certain restrictions depending on the location you travelled to.
Visit the Health Sciences Authority's website to learn more about the different factors that could affect your next donation date.
How can I plan my donation schedule so that I can contribute regularly while taking care of my personal/health needs?
We encourage donors to plan their next donation by taking note of the following:
To prevent bruising and to promote healing at the needle site, you need to avoid lifting or carrying heavy items for at least 12 hours.
You will also need to avoid undertaking any strenuous or athletic activities for 24 hours to enable your body to adjust to the donation.
Continue to hydrate yourself throughout the day to help your body replenish the donated blood.
For whole-blood donations, there is a waiting period of 12 weeks before you can make your next donation. For apheresis donations, the waiting period is 4 weeks.
Holiday periods/long weekends
Blood stocks tend to dip during long weekends and holiday periods. Consider scheduling your donation during holiday periods and long weekends. This would ensure that our blood-stock levels remain at healthy levels at a time when many regular donors may not be available.
