Order Estradiol Blood Test | Measure Estradiol Hormone LevelsThe Estradiol Blood Test measures the concentration of estradiol, a primary form of estrogen, in the bloodstream. Estradiol is produced mainly by the ovaries and adrenal glands in women, and it plays a central role in reproductive health, bone density, and cardiovascular function. This test provides a direct look at circulating estradiol levels, which can be useful for evaluating hormonal balance and monitoring conditions that affect estrogen production or regulation.
About Estradiol Blood Test | Measure Estradiol Hormone Levels in Pasadena
Estradiol is one of several estrogens, but it is the most potent and predominant form during reproductive years.
In women, estradiol is largely secreted by the ovaries, with smaller amounts from the adrenal glands and peripheral tissues. Its levels fluctuate predictably across the menstrual cycle, peaking just before ovulation. Because of this natural variation, the timing of a sample can influence results, and clinicians often interpret estradiol alongside other hormones such as follicle-stimulating hormone and luteinizing hormone.
In men, estradiol is present at much lower concentrations but still serves important functions, including bone maintenance and modulation of libido. It is produced through the conversion of testosterone by an enzyme called aromatase, which is found in fat tissue and other organs. Elevated or reduced estradiol in men can signal underlying endocrine or metabolic issues.
Measuring estradiol is common in fertility assessments, menopause evaluation, and monitoring of hormone therapy. It can also help investigate symptoms such as irregular periods, unexplained weight changes, or breast tenderness. Results are typically reported in picograms per milliliter (pg/mL) or picomoles per liter (pmol/L), and reference ranges vary by age, sex, and the laboratory performing the analysis.
