    If it’s critical, you don’t have time to take them to a weighing machine and measuring them.

    It’s also why most licenses have blood type listed.

        If it’s an emergency they’ll run O- because there isn’t time for that test, and if there’s no O- they’ll go based off info

          ah, I didn’t know about this - it does look like O- is used (and sometimes O+ if risk assessment allows when O- blood is not available).

          I’m also reading there are rapid tests used in emergencies, too.

      So what do they do for any of the millions of people without licenses?

      And what do they do in countries that don’t have this practice?

      You can insist its an important medical intervention if you want, but there must be options and process in place that do not require it. That alone means it is not essential.

        O- / O+

        But not enough people donate blood so they’re always pretty low on it, especially since not everyone who donates has those blood types.

          What does blood type have to do with weight… “take them to a weighing machine” or “give them O+/O-” makes no sense as a dichotomy.

        I don’t remember which states, but some countries do / did. El Salvador and Japan I believe are some. Finland doesn’t, but that’s because our ID can be scanned to get our medical info if needed, and we have Kela cards anyway as well even if you don’t have ID that do the same
