Dear colleagues, I need your opinion about one query situation; could we extend the expiry date of empty blood collection bag, in line with the separated blood component inside? In other words, would we be able to use blood component inside bag after bag expiration date of collecting bag itself (i.e. PRBC will be expired at 30/3/2014 but the expired date of bag itself - even empty - is 20/3/2014). Also, I will be so glade if you attach here any documentation about my question… Thanks a lot for your cooperation
