My latest bw showed serum test at >1500 on the Labcorp scale of 348-1197 with E2 at 40 on a scale of 0-70. My question is does E2 need to be lower say 20ish or does it matter given the level of test? I feel fine. No joint pain, libido is ok. Can E2 be based on a ratio to the serum test reading or does it need to be a more specific level?
