Hormone levels/assays are dependant upon the lab drawing and
analysing the sample.
** Canadian levels are the same as International units.
*** XXY "total testosterone levels may be falsely high as
serum hormone-binding globulin [SHBG]
levels in patients with KS are elevated, and free testosterone
levels, which may be a more accurate assessment of the androgen
status in KS, are low." (Cynthia M. Smyth and William J.
Bremner, Klinefelter Syndrome)
Percentage of Free Testosterone: .3% - 5% A normal male has about
2% of free unbound testosterone
To convert from ng/dL to nmol/L, multiply the ng/dL amount by 0.0347
