Before making an appointment to donate, it is important to be aware of some of the common reasons that could lead to an 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.
