Best to get a test like this.
Estradiol, Sensitive
Quest has this test to. You need to stay with the same lab my labs E2 goes down to 20 so we send my E2 to Quest.
If you had a test that said 24 and the range was <20 to 50 of something like that then your E2 was 24 the test was for a man just not a sensitive essay that goes down lower.

On my next blood test I am switching from LabCorp to Quest Diagnostic.
I do that because of the way the Quest diagnostic does the T tests (one of them).
It is going to be a new study to find out what I want from Quest Diagnostics.
If there is somebody who could help with mechanics of ordering for Quest Diagnostics,
I would really appreciate help.
Please make list for a whole, complete blood test, basic, TRT, GH, adrenals, thyroid, sugar
When I go to my doctor I have a list ready, (in proper order, abbreviations, ICD-9 codes and so on).
That way I am, hopefully, a minimal pain in the neck to him, and usually he obliges,
ask the nurse to fill up proper forms, scripts etc, he signs it, it is 1 or 2 minutes of his personal time.
He is happy to get rid of me, I am happy I got what I want.
What I want is an script plus filled order form, at least that how it worked for LabCorp.
Long time ago I stopped with a practice of letting the doctor's nurse take my blood.
Too little control, end results of poor quality, repeated blood draws, hard to get my copy of results,
when I finally get it, it is 5th generation unreadable xerox, etc, confusion, bad blood.
Not sure what I want to order at Quest Diagnostics when I want E2.
Here is a list of tests that Quest D. does

They have 3 tests for estradiol.
• Estradiol, Bioavailable
• Estradiol, Free
• Estradiol, Serum
Looks like it is going to be the last one, the
Estradiol, Serum (E2; Estradiol-17 Beta)
The range they have (10-50) look also similar.
It is all on page 64 of

===================================
But look at pages 62 & 63 upper right.
SHBG, more than 95% of circulating estrogens, including estradiol, are bounded by SHBG.
===================================
We should talk more about SHBG.
Also Estradiol-17 Beta, IIRC there are two of them, right and left.
Would we be better of if we knew how much of each one we have?
