got my labs back today...all were in normal levels exept a couple...havent talked with the dr yet...testosterone was 1113 but free testosterone was 356 (high). estrogen was 65.8 (high). not concerned with the estrogen but wondering where my free t should be and why is it high?
 
What are the lab reference ranges for these assays?

Free would be high if SHBG is low in combination with high Total Testosterone.

Need to see your SHBG assay.

If you don't have any symptoms with your E2 that high that may be fine...but that would be way to high for me personally.
 
DHEA 2.75 (.630-4.700 ng/mL)
Estradiol Ultrasensitive 65.8
Testostrerone 1113 (300-890 ng/dL)
Free Test 356 (47-244pg/mL)
Thyroid-------didnt check, son of a *****, its always been good tho

everything else on this sheet is just stuff like my postassium, RBC, Lymph, Mono, Triglycerides, HDL's and protein total and 50 other things that i dont think you want to see..

i guess i was just wondering how the free t should compare with the total t...???
 
Marshall, your free test is at 3.2%. That's not a bad place to be in the scheme of it all. IMO, 2% to 3% is the place to aim, so again, you're just marginally over that. Actually, that's pretty close in percentage to where I'm at also. As Gene stated, it's reflective on your SHBG, and loosely with your Albumin.

So, if you know 3.2% +/- is where you sit, it makes managing your program that much easier. If 3.2% is constant, then you don't need as much serum as the guy(s) with 2% or 2.5% to achieve the same net result. If you reduced your serum, let's say down to 700ng/dl, your free test would come in at 224 pg/ml. As you can see, it's all relevant to what your total serum is at. Finding the optimum zone on your free test will enable you to achieve a better balance in other areas, like E2, which looks high based on your posted results. Would of course want to confirm that with the reference range against that lab. The body seeks homeostasis. Too much testosterone will have an impact on how the body functions in many areas, thus leaving you having to fight unwanted sides and various forms of stress.

On the thyroid, seems 1/2 the guys get told or feel their thyroid is "good", where in fact it's not. We see T3 pooling problems, T4 deiodinase conversion issues, autoimmune complications like Hashis or Graves, and sometimes circulating TSH complications due to secondary related possibilities within the pituitary gland; disrupting the negative feedback loop. If you're certain you are "good" in this department, that works, but this is the place and the opportunity to really get some excellent feedback. My TSH came in one time many years back that was over 5.3 and my GP said "it's all good". Free T3 or T4 wasn't even factored, and you can only guess that Reverse T3, antibodies, and supporting labs that effect the thyroid productivity and activity were never even thought about with this physician. Just saying ... I have found that one perception of "good" can sometimes be a "not so good" with others. Let me know if you have any thoughts.
 
thanks chris,
i dont know why he didnt check my thyroid this time...unless theres a page he didnt send???? the last two times it was in range.. i really feel fine, other than i probably will be starting Hcg in the next couple of weeks. will have a consult later this week with defy...we will see what he says but i think everything is actually pretty good:)

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
