>> My only other thought is to do a documented study of the temperature of these outside storage boxes (they can be little hot/cold boxes depending on your location. Because, according to the inspectors, you must be able to assure temperature is within the required temps prior to receiving, including transportation. (Pre-analytical)
>> So, say you do a study of the temperatures during the hottest time of the day of the boxes for a period of time (30 days of the hottest month(s)) to give an indication of a potential problem, and document. That would be one portion of pre-analytical.

>> Then temperature during transportation (cars/vans can get quite hot/cold also needs to be addressed and documented daily just like the temperature logs in the labs. Many labs are getting cited for not providing good pre-analytical evidence. Courier services have to have temperature monitoring systems in place to provide as evidence. Some are quite savvy with alarm systems in place with monitoring. (ShipCom for example)

>>> Unless you do a well documented validation study that goes outside of these restrictions from the IFU that proves no patient harm, you honestly must go by the IFU recommendations. This would apply to all of our stains/reagents/solutions/antibodies.
