Hi...just wondering if anyone can tell me what a `normal' range for estradiol should be?
I know FSH is <10 and LH should be almost 1:1 or slightly lower than FSH but have no idea what the ideal range is for estradiol. I know that increased estradiol can mask a higher FSH but since I don't know what an `increased estradiol' reading would be it's not much help to me  -------------

Just found this on a fertility website:
Day 3 estradiol testing A blood estradiol level on day 3 (we do it on any day between days 2 and 4) of the menstrual cycle is a way to potentially discover some of those women with a normal day 3 FSH that may in fact have decreased egg quantity and quality. What we want on day three is a low FSH level in conjunction with a low estradiol level. If the FSH is normal but the estradiol level is elevated, the elevated estradiol will often be artificially "suppressing" the FSH level down to the normal range. The idea of using day 3 estradiol levels as an adjunct in evaluating egg quantity and quality is relatively recent. Clearly defined cutoff values for normal are not well established. We like to see the day 3 estradiol less than about 80. We repeat borderline or abnormal results in another menstrual cycle to try to get a "true" FSH. There is some evidence that an elevated day 3 estradiol indicates a problem with ovarian reserve. This is sometimes the case, but often the issue is just that the elevated estrogen level is "masking" the potential for detecting low reserve by suppressing FSH into the normal range. -------------

Given the above it would seem that is normal hun
That said, it was an american site so possibly they measure it differently. -------------
