Here's another
HCG travelling tip.
I bought a refridgerator thermometer for about $6 at Bed, Bath & Beyond. I put it in my freezer pack when I travel and in the refridgerator at my destination.
I use it to monitor the temperature of (a) my freezer pack when I arrive to make sure the freezer pack made it all the way through my journey and (b) the refrigerator at my destination. Often I find that the refrigerator at my destination is not set properly and I'm able to adjust it, accordingly. My recollection is that the old insert used to say that after reconstitution, the vial should be kept between 34 and 44 degrees. I can't find this info on the new insert. Refrigerators should generally be set for 38 to 40 degrees.
I also use the thermometer at home when I'm not travelling to set my own refridgerator.
