How are people testing testosterone etc?

Perhaps a silly question but how are people getting tested for their testosterone levels and evaluating results? Is this through a general practitioner or a urologist, or online home test kits?
Also, what is everyone testing? Just specifically free testosterone, or additionally things like cortisol and c-reactive protein (for inflammation)?
Since COVID finding a GP is difficult, many are filled up and stopped taking patients. My current urologist, who I now do not see very often, never mentioned testing these things, but I see that as a common thread on this forum so I am interested now.
I’m tempted to take these two tests, but need to research more if it’s just a waste of money:


Thanks for any input

In the USA you can use https://www.walkinlab.com/

I’d get the total T and direct (not calculated) free T.
