- rae_labels — power cut for 4 hours, fridge stayed shut, am i fine if you are worried after a bad transit, test it. that is what the testing channels are for 21:17
a few hours at room temperature is almost certainly nothing. a week is a different conversation, log it rather than guess
lyophilised is forgiving

power cut with the door shut for a few hours is fine. a full fridge holds temperature surprisingly well
a cheap logging thermometer costs less than one vial and tells you what your fridge actually does, provisionally
[edited]keep the box. the lot code and the certificate reference are on it
a cooler with two gel packs held under eight degrees for eleven hours on a drive, the pinned table has the numbers

logged my fridge, so the fridge is the easy part. the two days between the courier and you are where the uncertainty lives
i logged my fridge for six weeks and the door swung between 4.8 and nearly ten degrees. the shelf did not, 2 to 8 is the target not the law
