Then that should be the questions asked, not some arbitrary “sex” question with only some of the possible answers as options.

It should be apparent, especially now, that those things never were never enough to determine these things anyway. There are tons of types of intersex people which are not an insignificant percentage of the population.

So, there are some things that loosely follow AGAB for the majority of people, but the assumptions made based on that, end up causing more trouble for those whose bodies don’t conform. And that’s not a small portion of the population. Basically between intersex people and trans people who have had HRT and/or surgery are at very, very conservative estimates, around 3%, but since there’s no finding and it’s now unsafe to track even in the US and UK and other western countries, it’s likely much higher in reality. These people are poorly served by the current system of AGAB only.

For me, many of my lab tests show abnormal because it should ask what is my body’s primary sex hormone or ask to select for the specific test, what range is normal for my body if they want to get it really right. And honestly, body weight is more impactful on a lot of things anyway, why aren’t we asking that of every person (rhetorical question, but essentially asking if you were born with or the doctors modified your body at birth to have something that looked closer to a penis than a vulva, should be just as uncouth)? Also, insurance won’t pay for gynecology/urology kind of stuff or mammograms or prostate cancer screenings even if you have the right body parts to need it, if your AGAB is wrong without a long and drawn out process each and every time to prove you have the right part. Heck it’s not even good for marketing if you have the wrong one listed because it has to be your AGAB rather than the gender you present as and thus the high profit products you’re most likely to use.

So it really has a low usefulness compared to asking more relevant questions whether for medical or commercial reasons.
