Despite that fact that the reference ranges ARE different for MANY blood parameters, what about basic things like the presentation of the patient?
Young androgenous looking person presents in A&E with abdominal pain. Are we going to run every test for that patient? Are we going to do a full pelvic scan just on the off chance that this person may have ovaries and a uterus and may be having a miscarriage or a ruptured ovarian cyst or a massive uterine fibroid or worse?
Or are we just going to ask them what sex they are to instantly rule in/out those things?
Would Dr Upton just run the pelvic scan anyway, just in case? I mean, sex is nebulous right?
Or would the nurse who thinks clothes can change a person's DNA help out with the scan because the person might have grown ovaries if they sat too close to a pink pair of pants?
