An estradiol test, ultrasensitive, measures very low levels of estradiol, a form of estrogen, in the blood. It is ordered when standard estradiol tests are not sensitive enough, often to monitor hormone therapy or evaluate certain hormone-related conditions.

What it measures

  • Estradiol — The main estrogen measured; ultrasensitive methods detect very small amounts.
  • Total estradiol — The overall amount of estradiol in the blood sample.
  • Free estradiol (calculated) — The portion not bound to proteins, estimated from other results.
  • Sex hormone binding globulin (SHBG) — A protein that binds estradiol; sometimes measured to interpret free levels.
  • Testosterone (total) — Often checked alongside estradiol when hormone balance is evaluated.

Who it is for

A clinician may order this test for people receiving estrogen therapy, those with symptoms of hormone imbalance, or when monitoring certain treatments. It is also used in some fertility and gender-affirming care settings.

Preparation

No fasting is usually required. Tell your clinician about all medications, including estrogen products, as timing and dose can affect results.

Results and what they mean

Results are reported as a number with a reference range, which varies by age, sex, and lab method. A clinician interprets the result in the context of your symptoms, medications, and other tests. This is general information, not medical advice; discuss your results with a qualified healthcare professional.

Can my medications affect the result?
