Raised testosterone at age 47 with regular periods, could this be PCOS?

[Howmanychanges]

Hopefully someone can help!
I’m 47, have regular periods, had blood tests done recently and my testosterone level was 4.76, I have been referred to an endocrinologist. I know it could be a few things but am wondering if this is quite average for PCOS because most of what I’m reading just says referral at a certain level and it’s commonly raised in PCOS without specifics.

Should add it’s 4.76 nmol/l

Raised testosterone can happen with Polycystic Ovary Syndrome, but the endocrinologist referral is just to rule out anything else as well.
