I’ve been having the hardest time donating blood since the pandemic. No mobile blood drives and the alternative to the Red Cross is booked for weeks.. I was also told last time I used the Red Cross my numbers were too high and I’ll be denied forever until I call a number they gave me...
I have been donating blood every 2/3 months and my ferritin levels are low (11 - range 20-345) but my total iron is high (216 - range 50-180). Other test results below:
Iron binding capacity 482 - range 250-425
% saturation 45 - range 15-60
Any comments why is that? If dangerous and how to fix it?

Understanding Your Hormones
Estradiol (E2)
A form of estrogen produced from testosterone. Important for bone health, mood, and libido.
Too high can cause side effects; too low can affect well-being.
DHT
Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth,
prostate health, and masculinization effects.
Free Testosterone
The biologically active form of testosterone not bound to proteins.
Directly available for cellular uptake and biological effects.
