What this test is

This test quantifies estradiol, a form of estrogen, using a method designed to detect low concentrations accurately. It is typically requested when precise measurement of small amounts is important for clinical interpretation.

What it measures

  • Estradiol — reflects the concentration of this estrogen in the blood

What the test involves

A blood sample is collected from a vein in your arm, usually at a laboratory or clinic. The sample is then processed and analyzed using a specialized assay.

Why it is often ordered

A clinician may order this test to evaluate estrogen status in situations where standard tests might lack sensitivity, such as monitoring certain treatments or investigating hormonal symptoms. It can also be used to help assess conditions related to low or high estrogen levels.

Preparation

Preparation instructions can vary depending on the laboratory and the reason for testing. Always follow the specific instructions provided by the collection lab.

How results are reported

Results are reported as a numerical value for estradiol, often in picograms per milliliter or picomoles per liter. Reference ranges differ between laboratories and are influenced by factors such as age, sex, and menstrual cycle stage, so they must be interpreted by your clinician.

Before you go

  • Whether any medications or supplements could affect the test results
  • If there are specific timing requirements related to your menstrual cycle or treatment schedule
  • The laboratory's instructions for preparation and sample collection
