[QUOTE="DragonBits, post: 161550, member: 18023"] [B][USER=13851]@madman[/USER] [/B]stated [B]"Based on the new data on the distribution of free testosterone levels in healthy men the target range of free testosterone has been determined to be 164 to 314 pg/ml (mean+/−1SD)"[/B] One problem I have with Trut is that it requires me to measure shbg each time I measure total T, that is if I want to know free T. I don't often order the shbg test. I looked at those times I did measure both shbg and Free T, 5 out of 7 times the results when looking at their respective ranges were close enough. As an example, what I mean is when my free T measured by immunoassay was 24.7 (6.6-18.1 range), my calculated T by Trut was 48.64 (16-31 range). So both tests tell me I was over range, either by 36% or by 56% respectively. I didn't really need to know my exact free T, my total T of 1492 implied I would be well over. Now 2 times the TruT gave more insight, once my total T was 690, free T 20.7 (6.6-18.1) and truT 21.5 (16-31. Based on my total T, i was inclined not to believe the free T number, and thought the trut result more realistic. My DHEA at 450 30-295) was significantly over range that day, perhaps that influenced the results of the immunoassay test. BTW, the 16-31 range is NOT the really the "therapeutic target" range, its what was actually measured in "healthy men". We know there has been a generational decline in total / free testosterone, so the distribution of free T now days is lower than the distribution of free T used to be 50 years ago. So is that range really therapeutic if it was much higher 50 years ago? Just as average weight has gone up, if we take a distribution of normal, then average weight will be higher and BMI will be higher now. [/QUOTE]
