Let's say the specimen is going to expire at midnight, the red cell is still good for a couple of weeks, will you issue the product at 11:45pm knowing they will not infuse it before the outdate of the specimen? Yes, I would issue the product with 15 minutes left on the clock.
The patient requires a washed platelet. It only has a four hour outdate from the time you start washing it. It's going to outdate in 10 minutes, do you still issue it? Yes. but transfusion must be started before product expiration per Circular of Information. Close communication with nursing is important.
