E2 not sensitive taken - Labcorp screwup

I had my Defy follow up blood work done and the lab took the wrong test. It came back that my E2 was 20. If they did the correct test of 'sensitive' would that number generally come back higher or lower?
 
How did you verify that the wrong test was run? From the report - language on the report itself/the reference range? What is the reference range, and which lab performed the test? *Generally* speaking, the "standard" test, of no value to men, reports values higher than are actually present. Either way, it would be reasonable to say that you do NOT have elevated estradiol with that reading.
 
Estradiol 20.7 pg/mL 7.6 - 42.6 01
Roche ECLIA methodology

Just wondering if in general that my sensitive would be lower or higher given this number? I did find a website (http://www.peaktestosterone.com/Which_Estradiol_Test_Best.aspxf) suggesting that in general the standard will show numbers that are much higher than sensitive. If this is the case I might want to back off AI (currently .6 per week split in 2 dosages)

Although, I do feel great at this level.

I would leave it alone, not change anything, until the proper test is taken, but you say you're feeling great so that's all that matters, wrong test or right test.
Typically when I go in to the lab (I use Quest) they ask me to sign something verifying identity, address, etc.., I always look down and check the tests that they've entered and have had to correct them once when they entered the standard Estradiol test.

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.
