Letrozole and checking estrogen levels

I asked my oncologist when I first started the AIs back in March & he said that the bloodwork doesn’t show estrogen levels - that they are looking for cancer indicators in the bloodwork.
I would be very interested same as you, to find a way to check that specifically.

Studies cited in the Femara insert say that even at 20% dose, estradiol levels are not detectable. I don't see the usefulness of blood tests since studies showed that the meds were effective in basically eliminating the hormonal level. Maybe someone can explain why these tests would be helpful.
