Common Questions and Answers about Testosterone free

Total Testosterone will give a measure of both attached and free testosterone. And Free Testosterone is more specific and only measures free testosterone. Total T is the typical first test to get for diagnostic purposes. It's probably always the first test in hypogonadism. And normal range is usually (most labs) 300 to 800. About 1 to 2% (in most men) is free testosterone. The rest is attached. Free testosterone floats around and is biologically active.
As well, Which testosterone? Free, total? Did you have a sex binding hormone test done? All this would be part of a comprehensive androgen check.
The thing with hormones that docs seem to fail to remember from their training - is that they work in feedback loops. So if testosterone is low, other things are working overtime high to make up for it or not functioning at all - so the loop is broken. And since the androgen can come form the pit or the adrenals, they need to test you well.
my T count result is 134. and it says reference intercal is 348-1197 not sure what that means.
Of the total circulating testosterone, 60% is bound to sex hormone binding globulin (SHBG), 38% is bound to albumin, and 2% is free. Free testosterone is the biologically active form and is considered to be a better representation of the true testosterone status.
There are situations in which the total testosterone level is low but free testosterone levels are normal (your lab work shows low total serum and in range (albeit at the bottom of the range) free testosterone.
I did have a question for you on your testosterone. These ranges are different than ours over here and i wanted to know if this is testosterone FREE or TOTAL>? can you find out? The total is the important once, but free still needs to be within an acceptable range. This may also help contribute to the libido issue.
The total testosterone consists of two forms of testosterone; one is bound to SHBG and the other is free-circulating testosterone unattached to serum proteins.
In conditions such as hypothyroidism and cirrhosis, measurement of the total testosterone level may be normal but the patient may have symptoms of low testosterone. In these conditions, the SHBG is increased and this decreases the amount of testosterone that is available for use.
My testosterone level was at 304 when first diagnosed .Began treatment with testim and 32 days later level was at 104.This was confirmed by 2 different labs.My FSH IS 1.82 AND MY lh is .60 yes so low not on the chart.My primary physician consulted with a endocrinologist and she said run am cortisol,prolactin,free t4,igf-1.After these come back they are suggesting MRI of the pituitary gland. MY question is which of the last 4 tests would be the definer in if i should have an MRI or not and why.
Your doctor should also have ordered Free T3, along with the Free T4 and TSH... Free T3 is the thyroid hormone that individual cells in the body actually use, while FT4 is more or less a "storage hormone" and must be converted to Free T3 prior to use... It's possible that your body isn't doing the conversion adequately.
Your FT4 is at 58% of its range, which is higher than the recommended 50% of range... so your thyroid seems to be producing adequately.
Just wondering, how likely is it that your family doctor will tell you to see a urologist/endrocrinologist if your regular and free testosterone levels are below 300ng/dl? I know for medical costs, doctor's won't refer most people to these types of specialists unless their situations are dire, so that they can keep health care costs down.
Sidenote: I personally believe that my regular and free testosterone levels are below 100ng/dl.
Total T, Free Testosterone, SHBG and Estradiol. Yes estrogen.
If you have higher SHBG and/or higher estrogen it would be sucking all your Testosterone leaving little Free testosterone which is all your body uses and you will have low T symptoms.
Not saying it is one or the other or both. But at your age you have the total T level of about a 70 year old man! And that is NOT anything close to "normal".
Low levels of testosterone are linked to muscle and bone loss, coronary artery disease, diabetes, depression, erectile dysfunction and loss of self-esteem.
Been on the same dose of armour thyroid for about a year now. 6 months ago blood tests showed perfect thyroid levels. The ones last week showed a very elevated free t3 (over 8). Hair's falling out and I'm dropping weight. What happened? My thyroid was removed in 1994. I also recently had testosterone added to my compounded hormones.
Hello, Chap. I think your birth year coincides with mine. On to your question...
Before I get there, know that I am NOT a medical doctor. However, I do participate on testosterone forums (in fact, I belong to an excellent forum on yahoo which consists of men recovering from low testosterone. A few of the members there are medical doctors, as well.)
Libido is complicated, influenced by more than simply testosterone. That said, we should consider the actual results from your bloodwork.
