Hopeful, I think you mean Estrogen (usually estradiol, E2) levels, rather than ER (estrogen receptor) levels--those only being able to be tested on the tumor itself, circulating tumor cells (blood), if any, or disseminated tumor cells (bone marrow). I suppose one could also test for estrone(another form of estrogen), but don't think that is commonly done
