What’s the difference between E2 sensitive by LabCorp and E2 ultrasensitive by Quest?

I am going to stop the sensitive as mine are usually about the same result! The sensitive seems to hold up my results anyway. I know you guys like it but for me it is not worth it. My last Labcorp they forgot 3 test that had been ordered so look forward to trying quest soon. I am getting my last LabCorp shortly.

So do you plan on using the non-sens E2 in the future, or doing the sensitive, just with quest?
 
For me I have just never see much of a difference between the two tests. I have also noticed it is the one that holds up the results and can be inaccurate. I am sure I will use LC some because that is who my doctor uses but will use DL with quest.

This is the ultrasensitive estradiol from Quest


This is the sensitive estradiol from Labcorp that we used to sell (they are both the same but Quest chose to call theirs ultrasensitive)

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.
