Why am I having this test?
The estrogen fractions test is used to evaluate:
Sexual maturity, menstrual problems, and fertility problems in females.
The health of a fetus and placenta in pregnant females.
The presence of female characteristics in males (feminization syndromes).
This test can also be used as a tumor marker in people with estrogen-producing tumors.
What is being tested?
This test measures the levels of estrogen in the blood. There are three major forms of estrogen:
Estriol. Estriol is the major estrogen during pregnancy. Excretion increases around the eighth week of pregnancy and continues to rise until just before delivery.
Estradiol. In women, the level of estradiol fluctuates monthly during the course of a normal menstrual …show more content…
The combination of estrone and estradiol is called total estrogen level.
What kind of sample is taken?
This test can be performed using the following samples:
Blood. This is usually collected by inserting a needle into a blood vessel.
Urine. This is collected in sterile containers over a 24-hour period.
The choice of sample often depends upon what your health care provider is looking for.
