She has previously tested for high testosterone levels in a test that was, by the words of an IOC official, "cobbled together, as I understand, overnight [during the world championships] to change the results.” The nature of the tests was unspecified, and the governing body has been banned from the Olympics over governance and corruption issues. It has been insinuated that the unspecified test at the world championships was only administered by the Russian-led IBA after Khelif defeated a Russian athlete.
Khelif was born a woman, has identified as a woman all her life, and was even banned from boxing as a child by her father because he deemed it to be ‘not for girls’. She has competed for years, has wins and losses in her belt like any other athlete.
And yes, as you say, high testosterone levels in women can occur due to a variety of reasons, including medical ones. So we should not immediately suspect foul play when a high performing female athlete has above average testosterone.
Since I’m on my phone I am not going to deeplink each claim - receipts are in the following articles:

And one more thing: a man would never be subject to this kind of demeaning scrutiny even if he seriously outperforms his peers. Michael Phelps has unusual body features that give him an almost unfair edge over competitors. He has won 20 gold medals in his career. His success is attributed to skill and hard work. Katy Ledecky has matched his medal tally, and was subjected to the same suspicions and demeaning scrutiny as Khelif is now. Hint: there is no evidence that she is anything but a woman. The gender scrutiny of high performing female athletes goes back to the 1930s, because for some reason high performing women with a perceived unusual or ‘non-feminine’ physique are immediately suspect.
