How usefull is this in determining a problem and what is the percentage? My doctor told me a percentage that it should be that I cannot remember now.
My DHT seems to be lower than the T both before and after TRT. For instance when I was first on TRT, my T was very high - 1300, yet my DHT blood test (for what its worth) came back smack bang in the middle of range being 10 ref (2 - 20). While being mid range, when you compare it to how high the T was, it seems to be coming up short.
Before TRT my T was around 500 and my DHT was 2.3 (2 - 20).
Also I hear mixed advice about whether or not DHT is actually responsible for libido or not. Whats the go with this? I thought high DHT means high libido unless there is another issue going on.

Dr John Quote:
"We also now know that urine (and serum, for that matter) DHT levels are not necessarily reflective of actual intracellular 5-AR (which converts T into DHT) activity. The best biomarker for that process is the urine THF/5-allo-THF ratio. Often we see high serum (and therefore urine) DHT levels, but low ratios of metabolites from intracellular conversion. Or the other way around. For this reason, I no longer order a serum DHT level. The urinary DHT is included in the Rhein panel, so we have it to look at anyway."
I will get onto my doc over here to get that test. At the mo he is going by serum DHT.

Here are my last two serum DHT test results :
1. From last summer :
Dihydrotestosterone : 1 599 pmol/L ( Ref. range [men age 20-49] : 217 - 1650)
2. From this summer, a month ago or so :
Dihydrotestosterone : 2015 ( [male 20-49 yo] 217 - 1650) PMOL/L
I do have vertex MPB, and low to non-existent sex drive/libido whichever you choose to call it.
If high DHT is supposed to be driving libido, then something else is blocking in my case.
The above tests were done locally, well in Toronto, Canada actually, but back more than a year ago Dr. Eric Braverman measured my DHT and it came out low....so I wonder here, which is correct ?
DIHYDROTESTOSTERONE : 12.3 LO (16.0 -- 66.0)
So I'm a bit puzzled here as far as whether my DHT is high or low--but one thing remains ; terribly low sex drive.

I'm at a point where I'm in a bit of a tight spot for money, cause I'm expected to go back to school, have no insurance and have to pay out of pocket--while I can pay for these, I've had so many that I'm now wondering whether more from another lab will make any difference.

It is big difference between those tests.
If those tests are accurate enough it may signify some process going on.
Do you have plausible explanation?
I have similar history of tests but it was consistent with me either using Avodart (and Androgel) (very low DTH)
Androgel (very large application area, very high DHT, 3x over top range)
Tcream (small application area, DHT over the range, 1.5x over top range)

I'm more and more thinking the one M.D. who told me what causes my low libido is my lower than normal cortisol is probably right--this would account of the low T as well, and help with thyroid functions, although there's nothing really wrong with my thyroid at this point--so far it looks as though possible early Hashimoto's as my endo friend told me. My TPO is low btw.

I would appreciate some pointers, specially when dealing with Quest.
On my last test from Quest I got testosterone analyzed twice
once what I asked for;
Testosterone, Free, Bio/Total (LC/MS/MS)
but I got additionally the less desirable:
They did my prolactin and PSA twice
plus they did Albumin and SHGB second time unnecessarily.
I have made my doctor to write script for my test twice so I think the script was in order to the best of my abilities.
