What this test is

What it measures
- Total estrogen — reflects the combined level of estradiol, estrone, and estriol in the blood
What the test involves
A healthcare professional collects a small sample of blood, usually from a vein in your arm, using a standard blood draw. The sample is then sent to a laboratory for analysis.
Why it is often ordered
