Short story is, rectal, or in the bladder are the only accurate ones for when it really matters.Strangely I find myself 73 y/o and I have never owned a thermometer for checking my temperature. I am prepping for the pandemic, and it seems like a prudent purchase.
So......what to buy and why.......???
Note: Rectal so not an option.
So I guess Under the tongue it is going to be. Thanks that was helpful information.Short story is, rectal, or in the bladder are the only accurate ones for when it really matters.
In ear, or armpit are almost useless.
Under the tongue is so-so...takes about a minute to get a decent reading.
IR temporal are okay for a quick approximation but are only approximate. This is your best bet for just general "Do I have a fever" uses.
We don't even carry one in the ambulance because unless we are going up the butt, which we don't....nothing else is accurate enough to use for medicine.
