Ultrasensitive Estradiol test

Johndoessmith, that's a good catch. I inject 1000IU HCG 3x (M, W, F). The in house lab tests were done on a Monday before I even injected. The Quest labs were done on Tuesday morning. I don't believe that this should make such a big difference on E2.

It absolutely will. HCG is absorbed pretty quickly, so if you injected monday morning, then 24 hours later tested, a significant amount has been absorbed.

You cannot compare tests done under different conditions. I see you're new so you probably didn't know this, but these test results aren't proof of anything at this point.

AI dosing I'm not super familiar with, but I think standard starting dose is .25mg twice a week. If anyone else says I'm wrong with AI dose, listen to them instead of me lol.

Thanks Vince. The 0.25mg with the injection is part of the treatment. I didn't take any extra so as to do the test. I do injections M/W/F mornings and take AI Monday evening and Friday morning. Both tests were done on a Saturday.

You state here in this thread that you're not consistent with your testing. It can only be said in so many ways that you're changing the conditions of the test, you say as much right here in this thread of yours.
 
Vince, the in house labs that you quote above were done on a Monday but I don't take thim into consideration since my Dr's office uses the standard E2 test.

The three labs I posted earlier today and did myself with Quest D (no DiscountedLabs in MA :( ) all used the ultrasensitive E2 test and ALL were done one day AFTER HCG injection. I believe it's legitimate to compare these three labs.

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.
