QuoteTrue, but the estrogen test is unnecessary.
It is very necessary. Too low of numbers will yield poor results and you might be years before you know. Too high of the numbers can be dangerous to your health then it is too late.
I would like to reword my statement. An estrogen test could very likely be inaccurate. I found the following from a yahoo group I used to post on and if you can disprove this, I would welcome the discourse. But, more importantly I fully trust my personal physician, and if he thinks I don't need one, then I don't. But here is something to back up what I was saying:
1) Estradiol levels taken at a certain point in time do not reflect
your average level, due to fluctuation, especially (but not solely)
in the case of injectables, oral and sublingual. Another reason why
estradiol levels are an incorrect measure of what is really going in
your body. The test may give you the false impression that your
levels are in a certain range when, in reality, they fall under and
rise above that range periodically.
2) There is the issue of estradiol (estrogen) sensitivity (i.e.
genetics) which is also important and is not measured by labs. Some
may be more sensitive than others and thus an acceptable (i.e.
effective) level for one may be too much or too little for the other.
Add to that, the fact that different tissues/areas of the body
metabolize estrogen differently (i.e. configuration of enzymes such
as 17-HSD, aromatase, sulfatase) and respond weaker or stronger to
estrogen, as a result. So that a suitable level for one area of the
body (i.e. to trigger enough changes wanted) is not suitable for
another, being too much or too little. Relying on a predetermined
level does not take into account this reality and finding the correct
balance for oneself can be better achieved by titrating doses as a
function of outcomes.
3)Serum (blood) estradiol levels are also often inaccurate and
misleading, as they often don't correlate with tissue levels, where
it counts the most. Tissues can convert estradiol to weaker
estrogens (estrone, estriol) or inactive compounds and amplify
estrogenic action through local synthesis or conversion of androgens
into estrogens.
