Your request stays private, and you choose where the specimen is collected. Because individual sites vary, double-check the lab's own guidance on preparation, timing, and cost.

What it measures

  • Estradiol (E2) — The primary estrogen made by the ovaries and, in smaller amounts, by other tissues.
  • Total estradiol — The overall amount of estradiol circulating in the blood.
  • Free estradiol — The small portion not bound to proteins and available to body tissues.
  • Related hormones — Sometimes measured alongside FSH, LH, or progesterone to give context.

Preparation

Preparation depends on why the test is ordered; some providers ask for a specific day of your menstrual cycle. Fasting is usually not required unless other tests are done at the same time.

Results and what they mean

Results are reported as a number in picograms per milliliter (pg/mL) or similar units, often with a reference range that varies by age, sex, and cycle timing. A clinician interprets your result alongside your symptoms and history. This is general information, not medical advice; discuss your results with a qualified healthcare professional.
