Just curious... when you say "piss poor" are we talking plus or minus 200 range? If I measured 1200, how much could it be off by?
The direct immunoassay is inaccurate.
You can get a rough idea by using one of the calculated FT methods available online (cFTV/cFTZ).
Mind you there can be an extreme difference between the two especially in cases of altered SHBG.
As I stated earlier in Canada they mainly rely upon the older outdated linear law-of-mass action cFTV as the direct immunoassay is no longer used.
Unfortunately, the only way to know where your FT level truly sits is to have it tested using the most accurate assays such as the gold standard Equilibrium Dialysis or Ultrafiltration (next best).
Access to the most accurate assays ED or UF is only available to some.
Depending on your treating physician and where blood work is done as only certain labs would offer such testing methods.
*It is currently limited to mainly reference laboratories but serves as the standard in all investigational studies of testosterone measurement.
Either way, seeing as on your most recent labs posted in a previous thread with a very high trough TT 1300s ng/dL and SHBG 33 nmol/L (normal) you can rest assured that your trough FT will most likely be absurdly high (40-50 ng/dL).
I'm on 120mg/week enanthate sub q (2 x 60mg/week) and nothing else (other than OTC supplements). I can't believe how much my T levels increased. I met with my doctor this morning and he is adding a low dose AI to bring down the E a bit but otherwise everything looks great. And most importantly...

A FT 5-10 ng/dL would be considered low.
FT 16-31 ng/dL (high-end) is considered healthy.
Most men on trt will do well having FT in the 20-30 ng/dL range.
Your trough FT will easily be well over 30 ng/dL!
