Estradiol - standard vs. ultrasensitive

[LeanGuy]

When testing estradiol, how much can it differ between standard & ultrasensitive? Has anyone done both at the same time? I've never done the ultra before. I'm wondering if my standard 29 might actually be high when re-tested ultra?

I found a lab online that at least has a "sensitive" estradiol test (LabCorp) suitable for men:

Online blood testing lab tests, STD testing blood tests lab test by Private MD

I wish I could find a place to order quest ultra, but I doubt it.

Estradiol, Sensitive

Description: This sensitive estradiol assay is designed for the investigation of infertility, particularly in situations where low estradiol levels can be expected. The analytic range of the assay is appropriate for the assessment of the low levels of estradiol typically observed in men, prepubertal girls, and postmenopausal women.
