Safety is at the forefront of everything we do, and this is the reason we have one of the safest blood supplies in the world. If someone gives blood during the window period, their blood could contain an infection that could be passed on to the people who receive their blood. This is because there is a period of time (called a window period) between getting an infection and it showing up reliably on tests. We test every blood donation but there is a small possibility that very recent infections don’t get picked up but may still be passed on through blood. The gap between getting an infection and being able to detect it The reason a delay period exists is due to a combination of two things: Increased risk of infectionĪt a behavioural level, having anal sex with new or multiple partners is associated with a higher risk of acquiring blood borne infections. This applies to all donors whose partners may be at a higher risk of blood borne infections. The 3-month wait is to reduce the risk of any very recently acquired infections not being detected on screening and further tests.
