I thought "bio-available" and "free" meant the same.
Also, units for above quantities? ng/dL and/or pg/mL ?
My recent test results show total = 630 ng/dL and free = 64.9 pg/mL. Both #s are within some nominal ranges of (250, 1100) and (35,155), respectively. I suppose that's why they aren't drawing comments from the doctor.
Thanks,
Vince
