Interpretation of hormone testing using saliva, dried blood spot, or serum can be tricky when women are using oral, patch, or other hormonal contraception methods. The types of hormones in these contraceptives are synthetic, and although they may be close to the molecular structure of our body's own estradiol or progesterone, they are not bioidentical. While bioidentical hormones used as…
