I asked the doctor to specifically test my ferritin levels, she did: %SAT, dTIBC, FE and Trans. Is FE the ferritin?? Or did she not do it? I can't seem to find the answer in my online searches. I did find out my zinc is low. So I need to up that. I want to start Rogaine soon.. I am so nervous about it. It will either work and I am worried about the big shed or it won't work and that would be awful too!
