It helps to ask what evidence would change your mind before you look at any.

This matches mine closely enough to be worth saying so out loud.

Adding the part of the answer the thread has not reached. Start from the measurement rather than the conclusion. Almost every disagreement here turns out to be two people measuring different things and comparing the numbers anyway.

Ask again with the specifics and you will get a better answer than this one.

One concrete data point for the thread. Worth stating the units and the reference range whenever you post a number here. A large fraction of the apparent disagreement in these threads is two people using different units and both being right.

If somebody has the primary source to hand I would rather cite it than paraphrase it.

Following on from SarahChen_PharmD — and this may be the naive question:

Was that from a primary source or from a summary of one?

Closing the loop on my own question.

Update: the excursion was survivable and the vial was fine. I now keep a cheap fridge thermometer, which costs nothing and ends the argument.
