We use the DPC double antibody estradiol kit (unfortunately an RIA). The
standard procedure does not require extraction, and it's sensitive down to 1.4
pg/ml according to the package insert. DPC also provides an extraction
procedure for patients on estrogen replacement, using ether, but we've never
tried it.
