The units of measurement which Life Extension uses are different from those from the laboratory that analyzed my blood tests. Life Extension says these are the optimal ranges for estradiol, total testosterone and free testosterone:
Estradiol: 20-30 pg/mL
Total Testosterone: 700-900 ng/dL
Free Testosterone: 20-25 pg/mLThe laboratory that analyzed my blood tests says these are the normal ranges for testosterone and estradiol:
testosterone: 6,7 - 31,9 nmol/L
(I had 5,9 on the first - and 16,0 nmol/L on the second test)estradiol: 20 - 130 pmol/L
(I had 78 pmol/L)I found this table for converting conventional units to SI units:
http://www.unc.edu/~rowlett/units/scales/clinical_data.htmlFor testosterone, the table shows how to convert from ng/dL to nmol/L and for estradiol how to convert from pg/mL to pmol/L.
I have calculated that I had 21,247 pg/mL estradiol on the blood test, which is in the low end of the Life Extension optimal range (20-30), and 170 and 461 ng/dL total testosterone, far below the Life Extension optimal range for total testosterone (700-900). That is, if the laboratory test was for total testosterone. It didn't say if it was total or free testosterone, and they only have one type of testosterone test.
This means that I need testosterone replacement therapy to come up to 700 - 900 ng/dL total testosterone, but it may be difficult to find a doctor who will prescribe testosterone gel or injections when my testosterone levels (on the second test) were normal according to the laboratory that analyzed it.
