Avatar m tn 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.
Avatar m tn free testosterone is the most important test for testosterone...ask doc for that. if youre curious my ;ast numbers for the 3 were total test(stupid endo didnt do free)....535 http://www.medhelp.
Avatar m tn 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.
Avatar m tn 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.

Avatar n tn Hi, As can be seen from the following link, an young adult male can have a serum testosterone (T) level in the range of 300 to 950 nanogram per deciliter of blood. : http://www.mayomedicallaboratories.com/test-catalog/Clinical+and+Interpretive/83686 This range also slightly varies among different labs. The broad range is to cover a larger population base. It is is also expected that with age the T level reduces by about 1% per year after the age of 30 years.
Avatar f tn Feeling wired, excess hair, lean body, irregular periods and excess testosterone production all seem to point to it. Get your testosterone, free testosterone, DHEA and androsteneidione tested- they vary depending on where you are on your cycle, so ask your endo when you should get them tested.
