Testing BF and Test?

How do you all get your body fat and testosterone levels tested?

Do you measure body fat at physical theapy centers? Do you make an appointment with your doctor for this? Do they do that at gyms? What does it cost? Is there a way to do that at home?

As for testosterone, this is probably a doctor thing. Do you just ask for a testosterone blood test even if there’s no symptom of t-defiency?
