Hi Brenda Due to past experiences with blood bank and now cord blood banking........ 1.if you are using these coolers i will prefer to validate them individually. Have you given them different equipment/ consumable numbers. Work a standard PQ form and use it for them. 2. Yes i would say to the 2nd point as well, since the term long term or short term storage has not been mentioned. Hope it helps.........since we just went through with our AABB and passed the same.
