Then, a needle is inserted into a vein (usually in the arm inside of the elbow or on the back of the hand) and blood is withdrawn and collected in a vial or syringe.

First, the skin surface is cleaned with antiseptic, and an elastic band (tourniquet) is placed around the upper arm to apply pressure and cause the vein to swell with blood.

page 2 The ProcedureР”Р„ health professional will usually draw the blood from a vein.

On the day of the test, having your child wear a T-shirt or short-sleeved shirt can make things easier for your child and the technician who will be drawing the blood.

No special preparations are needed for this test. Testing estradiol levels also can be used to monitor the progression of a pregnancy, fertility treatments, or to evaluate menopause symptoms. The test may also be used in boys or girls to check for damage or disease of the testes, ovaries, or adrenal glands. This can help doctors evaluate menstrual problems, including abnormal bleeding or missing periods. High levels are associated with precocious (early) puberty, while low levels may indicate a delay in sexual development.Р”В®stradiol levels also give important information on the functioning of the ovaries. Why It's DoneР”Вoctors may order an estradiol test if a girl appears to be entering puberty earlier or later than expected. Taken together, the results can often provide a more complete picture of a person's sexual maturation status and help doctors diagnose diseases causing sex hormone imbalances. Increased estradiol production is largely responsible for breast development, genital growth, and changes in the distribution of body fat in pubescent girls.Р”В«ecause human sex hormones work so closely with one another, doctors often perform the estradiol test with tests for LH, FSH, testosterone (the male sex hormone - but teen and adult females produce some, too), and progesterone (the hormone that prepares the body for pregnancy). As puberty approaches, usually between ages 8 and 14, the pituitary gland, located just beneath the brain, secretes two hormones (luteinizing hormone, or LH and follicle-stimulating hormone, or FSH) that work together to stimulate the ovaries to make estradiol. In young girls, estradiol levels are normally low. Sexually mature males have much lower blood levels of estradiol, which are produced by the testes and adrenal glands. Estrogen is also produced by the placenta during pregnancy. In sexually mature females, it's produced mainly by the ovaries, and in smaller amounts by the adrenal glands. Estradiol plays an important role in sexual development: It's the most important form of the hormone estrogen. An estradiol test measures the level of the hormone estradiol in the bloodstream.
