[QUOTE="Cataceous, post: 177032, member: 38109"] The main issue is that if you're relying on direct free T to make clinical decisions then there's a greater chance of making mistakes. If you have enough SHBG and TT data then you can generate Tru-T numbers to compare to previous direct free T values, which is basically what I did with my lab results. The bare minimum usefulness to Tru-T is to compare your numbers to the healthy target range of 16-31 ng/dL. But I've been able to take things further, using Tru-T in reverse to predict my testosterone lab results so accurately that I almost don't need to test, and that's even while using a combination of testosterone esters. You also don't touch on the the issue of consistency. You say direct free T should be 20-35. Which units? Presumably pg/mL. Which lab? Don't think for a second that LabCorp and Quest have interchangeable free T ranges. This creates another opportunity for significant misunderstandings and errors. The point is that total testosterone and SHBG are more likely to be accurate and harmonious across different labs, making Tru-T a measure that is closer to universal. [/QUOTE]
