These ranges are known to differ between cisgender men and women, but it is unclear what a “healthy” range is for trans men and women taking hormones – a situation doctors have said could put trans patients at risk of receiving the wrong dose of a medication, diseases being missed or even conditions being erroneously diagnosed.
Among those attempting to resolve the issue is Devon Buchanan, a clinical scientist with Synnovis who is running a trial based at King’s College hospital that began in April 2021 and is recruiting 240 trans and non-binary people.
“We know that those ‘normal’ ranges are affected by gender affirming hormone therapy which a lot of trans people take and is very important to them,” she said.
Many previous studies have been small and the results unclear. “We wanted to cover a wide variety of tests and also have a larger sample size so that we could be more sure about the results,” said Buchanan.
This is hugely dangerous. What they’re saying is there are male ranges and female ranges and there should be “trans ranges”. But this is false. If a female on testosterone has a measurement of a particular marker that is outside the normal female range and in the “trans man range”, they likely have pathology. They may well be “normal” for a trans man, but it’s abnormal for a female and therefore causing disease.
“Your level of X is high, which for a woman would be a big concern. But you’re not a woman! For a trans man this level is in our normal range. Nothing to worry about. Off you go.”
It’s so incredibly self defeating to ignore the reality of sex.
