i wash my hands & use hand sanitizer a lot in order to keep my hands clean for testing my sugar, my hands are always dry!
Washing with simple soap & water or even just plain water is a reasonable thing to do before checking your BG (Blood Glucose) with a meter. Using hand sanitizer, not so much.
The best case scenario is your hands are uncontaminated before the test and the hand sanitizer does not interfere with the result. But if your hands are already contaminated with something that might interfere with a BG (Blood Glucose) test, hand sanitizer is most likely to just smear it around a bit rather than remove it.
While I try to wash my hands before testing at least a few times during a day, I also don’t always bother to wash them if I believe they are already “clean enough”. For example, if I test while in bed I’m not going to get up to wash my hands before I test unless I’ve been eating fruit or handling glucose tabs before the test.
If you are in doubt about whether you hands need to be washed but you are in a position where you can’t easily do that, the best suggestion I feel I’ve seen is to wipe away the first drop of blood and use the second. Just washing with water and no soap (if it’s not available) and then using the second drop even better.

But I’d skip the hand sanitizer. The main benefit from using it most likely accrues to the company which sells it.
I once saw a post from someone who suggested a pre-test washing product which was “guaranteed” to not interfere with BG test results. When I looked at the ingredient list I found that it was a “solution of water and 0.9% Sodium Chloride”. In other words, it was salt water.
