Question

Quizplus · Accepted Answer

The approved shelf-life of red blood cell components using one of the three additive solutions (AS-1, AS-3, or AS-5) is 42 days. This is because the additive solutions help to preserve the red blood cells by providing nutrients and stabilizing the pH. However, after 42 days, the cells begin to break down and may not be as effective in carrying oxygen to the body's tissues. Therefore, red blood cell components must be transfused or discarded by day 42.
