HARMONS TESTS

Hormone blood tests can reveal an abundance of important information about a woman's health. Levels of estrogen can reveal where a woman is in her menstrual cycle, for example, which can help pinpoint the cause of fertility problems or signal the onset of menopause.
Blood tests to measure female hormone levels also can play a role in diagnosing medical conditions such as thyroid disease or diabetes, and they can help evaluate how well a medication is working.
The female hormones typically evaluated—often as part of a comprehensive hormone panel in which more than one hormone is tested—are estrogen, progesterone, follicle-stimulating hormone (FSH), testosterone/DHEA, and thyroid hormones.3 What the results of testing these hormones mean will depend on whether the levels are higher than normal or lower than normal.
