Blood Results, Is 500 Normal for 17 Yrs Old?

Just got back from the doc and I have Levels around 500 and I’m 17.
I’ve heard thIs is normal for me, but also normal for aging men in their 40s and not when I am in puberty.
Well which one is it? I have history of depression, hard time gaining and zero sex drive, with little facial hair
Tests also showed high calcium.
