Estradiol Ultrasensitive or not?
so I have heard that the only useful E2 assay is the sensitive or ultrasensitive test, not the regular one. Is this the general consensus? The regular assay from Labcorp runs $47, while the sensitive one runs $180 - pretty steep if you are paying yourself.
Would the regular test be of any value?
thanks in advance.

that is interesting - in the past I had an ultrasensitive test done and got the same very low result, while the "regular" estradiol test showed a much more realistic value of 30

so I suppose the question remains, is the standard (non-sensitive) Estradiol test of any utility for a male?

The E2 have to be ultrasensitive to have value.
On my last test I did not get all that I want, but at least I have a list that you can take a look at here, post #1:
Jan's BloodTest April13/2007
66 Estradiol 45 pg/mL ( <52 )
67 Estradiol, Bioavailable ( )
68 Estradiol, Free ( )
69 Estradiol, Ultra-sensitive 27 pg/mL ( 10-50 )
70 Estrogens, Total, Serum 60 pg/mL ( 130 or less )
71 Estrone,serum 33 pg/mL ( <or=68 )

The fractionated is interesting, it checks E1, E2, E3
and the E2's range looks like the one in ultrasenistive E2 test.

Saids that essay less then <29 are worthless because it does not tell you the range were you are at ..and mainly only used by females NOT MALES ..

Ok, here seems to be part of the issue.
if you look at the PDF manual from quest, it lists test number 30289x as having the range of 10 to 50, ultrasensitive by extraction, this is clearly the test Dr. Crisler wants to have done.
Now, If you look at quest's online test menu, same test number, it lists the Estradiol ultrasensitive test per the below.
so the problem is, I had the below test done, we waited 10 days for it and it just showed 3 as the result, for the less than 29 range. What we really want is the 10 to 50 range done, but per the online menu, the same test code is listed with different ranges.
so what are we do to? I have a blood test planned for next week and I certainly don't want to pay all that money, wait another 10 days to get another <29 test result back.

jansz that manual is copyrighted 2004 not 2007 LOL and ranges are all diffrent I swear its like the drs want us sick !!
the new reference range for dhea-s is 100-397 not 600 like before and they reduce the high free T to 155 vs 210

I had to go to separate web pages for the lattest (Free BioAvailable and Total Testosterone) test. See SHBG ranges changed big.
64 Progesterone 1.4 mg/mL ( <1.4 ) ☺☻
66 Estradiol 45 pg/mL ( <52 ) not listed
69 Estradiol, Ultra-sensitive 27 pg/mL ( 10-50 ) ☺☻ Estradiol, Serum
70 Estrogens, Total, Serum 60 pg/mL ( 130 or less ) ☺☻
71 Estrone,serum 33 pg/mL ( <or=68 ) (15-65)
78 Testosterone Total 510 ng/dL ( 260-1000 ) ☺☻ this is as part with Ft only (bad)
79 Testosterone, %Free 1.8 % ( 1.0-2.7 )
80 Testosterone, Free 89.6 pg/mL ( 50.0-210.0 ) ☺☻ this is the bad Ft test
81 SHBG 24 nmol/L ( 23-38 ) (7-50) big change
82 Albumin 4.6 g/dL ( 3.2-4.6 )
83 Dihydrotestosterone DHT 143 ng/dL ( 25-75 ) ☺☻
Tests below are not listed in EndoManual
I got ranges from
and then Reference Range See Tables 1, 2, and 3.
72 Testosterone, Free, Bio/Tot ( )
73 Testosterone Total 456 ng/dL ( 250-1100 ) ☺☻ table #1
74 Testosterone Free 91 pg/mL ( 46.0-224.0 ) ☺☻ table #1
75 Testosterone Bioavailable 179 ng/dL ( 110.0-575.0 ) ☺☻ table #1
76 SHBG 20 nmol/L ( 23-38 ) (7-50) table#3--------big change
77 Albumin, serum 4.3 g/dL ( 3.6-5.1 ) (3.7-5.1) table #3

Lots of good info.
this web site is not Quest Diagnostic
St Louis Children's hospital.
So, it is secondary information.
For example, on SHBG test the site was updated 4/06
the ranges are Males: 20-60 nmol/l
SEX HORMONE BINDING GLOBULIN (SHBG), SERUM
and it is different then one taken directly from Quest, (23-38)
There are changes going in testing, cutting edge everywhere.
They do not offer
(Free BioAvailable and Total Testosterone) test

So I just spoke to Quest re 30289 - ultrasensitve assay. I started out in baltimore and finally ended up at the lab out west that runs the test. This is the right assay for the sensitve extration method, and whatever the value is (be it 20 or 55) it will be reported, however the normal range is listed less than 29.
The tech indicated that very low values, like mine was at 3, could be due to poor handling of the sample (only stable for 48hrs room temp) or other issues with the test.
next time I run this test I'll also run the standard estradiol to compare values.
