I’m 45 years old and scheduled for my yearly physical in a couple weeks. I requested my blood test to include a view into my testosterone, free, bio, total, etc. The last time I had this done was 2017 and my doctor felt the results were “normal” – pasted below for reference. As I head in for an updated view, I’d love perspective from the group on my 2017 results. As a side, I’ve been feeling run down and had vitamin D levels checked (among other things) and my vitamin D clocked in low at 24 ng/mL (normal range: 30 - 100 ng/mL) and doc recommended supplementing with 800 IUs of Vitamin D3. From my untrained eye, my free test (62.4) and my bioavailable test (114.8) both sit at the bottom of the standard range. Does this provide reason to have a conversation and explore options?
Thanks in advance for your feedback!
